It really wasn't that simple. I was disconnecting one circuit at a time. The 15 volt rail goes to sc board via the a, it also goes to the ss board and to a board on multiple lines. Pin 1 and 2 on the connector goes to audio amp. You can see I cut those first and then reconnected and taped them when I moved to pin 3 to isolate short. Then disconnected flat jumper wire that runs from a board to sc board. This repair was spread over 2 days.
Thanks for taking the time to give us some insight into repair. I have a 2010 Panasonic L32C22 that would either not come on at all, or come on for 3 or 4 sec, then give a 4 flash light. Took it apart and noticed a burnt smell, looked real close at the Power board, the smell was really light. I used my nose and went over the board, everything looked like new. even tho this tv is 9 years old, its only been used for maybe a year. while looking at the soldier connections, I noticed one of the things that look like a alien and blue, one of the soldier connections seemed a little off color, just slightly. so I re flowed it prayed and put everything back together again. Perfect picture Lesson learned....use your nose.
+1. Very nice. .. Always a pleasure of watching a gifted/skilled professional. .. Drilling down the defect cause is an ole sckool practice given today's "swap out" contemporary circuit architecture. .. Thanks, M/S
Brilliant! I love the minimalist approach to most things you do. I'm so used seeing people go straight for a bench PS with current limiting and hitting the board with freeze spray, etc. Had going for a minute with the fusible resistor that morphed into current sensing resistor.
Nope current sensing. Very low ohms. Like a fuse resistor. Once I blew up the schematic I could see the current sensing loop which fires a transistor that feeds back to the power supply micro that shuts everything down.
@Martin P. I am serious when I say I know little about plasma TV. I did take a course in 2002 but that was board replacement only. I just use common sense troubleshooting. Isolate and conquer. Everything I know about plasma TV I learned myself. I pass this on in the hope that others will get something out of it. At least people are interested in fixing plasma sets because you can't buy them anymore. They are also the most complex of all the TVs. LCD and oled are pretty much non serviceable as much of the signal processing is in the panel itself.
Hi 12 volt vids... I have the exact same problem with a Panasonic TH-P50U20Z. I can't find the service manual anywhere. Is it possible for you to email me the service manual for the 46 inch? The boards and the layout appear to be the same. Cheers V3FMRADIO@OUTLOOK.COM
Seriously, someone would give this a thumbs down? I get such pleasure when the repaired tv comes back to life. I can’t believe there is someone who would do that. It is a joy to watch his troubleshooting as he zeros in on the problem. As the commercial says, “Are you not entertained?!?!” Please explain yourself or forever be labeled a pure ass!
same here im currently watchin this on a 47 in vizio i repaired videos likes this helpd me out when it finally comes on after looking for the problem that feeling kinda feels like elation lol
Trolls will be trolls. Could be someone that runs a shop. I am sure that are professional techs lurking here looking for information to boost their business. Come here to see what goes wrong and then thumb down the work because they cant stand someone informing their customers what goes wrong so they cant charge an arm and leg. Same goes when I showed how to snake a clogged drain using an 18.00 rental auger snake. Plumbers will be pissed off because for everyone that now knows how to do it, that is 1 less customer willing to pay them 200+ to come out and do the same thing.
Good grief, ceramic cap. Just knew it was gonna be the IC chips needed heat sinked back down. Always learning something from you. Thanks for the vid. I knew this was time consuming.
I am researching why my Panasonic plasma will not power up, (a TC-P42S60 that was given to me, saved from the dumpster, 3 blink code). thanks for the video and glad to see you got yours fixed......and what a COOL KITTY you have! :-)
Thank you for the detailed video. It worked for me. Advise for others... Be gentle during removal, I damaged some solder pads. But repaired them and the TV is fine. BTW, the HDMI plugs must be grounded. If you are testing the TV with the back off, jumper the HDMI plugs to chassis ground.
Very well done tutorial video! Thank you. Now it's my turn to diagnose my Panasonic TH-42PX60U Plasma with what must be a bad cap on the power supply board, with a Cold TV I activate a start button and get the Click/Power Light on/off cycling for 10 min then it works for hours with no issue.
I'm glad I found your channel. Its not only interesting but its informative. I never repaired anything in my life. But its good to watch just in case I get a hold of something I actually want to @t a S-VHS VCR or a Minidisk deck ( which I already have,Still working) . You have a subscriber for life.
Good job! You say you have limited experience with Plasma but a solid foundation of electronic diagnosis and repair you can figure it out with a schematic.
Plasma TVs just have to be saved. They were the last sets that had some good engineering in them, especially Panasonic sets. I now have 5 functional Panasonic and 1 to fix.
I've been watching lots of your videos, have to say your awesome. I dont have a RU-vid channel but covered some repairs on my Facebook. I only wished could get back in work doing this. Keep up the good work.
Well i am trying to limit how much i work on these days. Pretty much sticking to vintage audio and some video. I look at the stats and audio brings in the views, thus money, camcorders, tv and VCR not so much. So if there is little fibiancial gain for the video then i question why bother and that affects my decision to make a video, or to put a huge amount of effort into it. Vintage audio on the other hand views take off so that is what I put more effort into.
Love my plasma sets. I have 1 led set, a 4k and seldom turn it on. I think I use the old crt set more than the led. Use it only for checking 4k content before I upload.
That's a good one. Well I have an LED set, I use at my shop. I like it. Once I saw the plasma, holly crap, its like a crt hi def plus. Really bright and brilliant colours. Any info on the Philipps? I think its 52".
@@markanderson350 LED/LCD are light sources with an LCD "shutter" to restrict the light. Plasma (and OLED) are tiny points of light generated by the panel. OLED uses organic LEDs and plasma each pixel is essentially a tiny fluorescent lamp.
I love your cat... we have six... we call them our kids with paws. :) He's focused on you as you work... maybe someday he'll be able to assist in your repairs ;)
A nice tv for the price of a ceramic capacitor, sorted! Worth the time spent investigating. A new board would have went in to quite a few methinks! I hate the way we throw everything away these days!
Well done my friend: I have a Panasonic plasma TV have same prob 15 volt is missing have 10 blink red light.I did not check main board yet. hope can fix the TV by checking main board may be the regulator: Thank you for your professional skill and sharing:
So if the two lights on the boards do not light up as you show in the beginning, what does that indicate? Sorry for the newbie question hopefully you can help.
Great video. Last night i brought home a 55" Panasonic plasma that doesn't turn on. Hopefully I can repair it. I have repaired 3 LCD TVs, this is my first plasma.
I just went the dummy route on the A board of my cheap 58" Panasonic plasma. I wish it was just a shorted cap on mine. I have read that the eeproms on the bigger sets can become corrupted and cause the dreaded 10 blink code. I paid $50 for the set and $60 for a used A board. Unbelievable picture on the set. It's a keeper. I saw one on Craigslist going for $600, so I believe that people are actually starting to appreciate the quality of construction and the picture on these sets. It's the fifth plasma that I have saved from the scrap heap. They can keep those throw away LCD's.
I have 5 spare plasma sets. A 42 lg. The rest are Panasonic. 42 thx certified. 46 and 50, plus a 50 monitor with separate signal box. Those are spare sets. I currently use a 42 Panasonic on my edit suite and have samsung 63 in my media room. My bedroom 50 samsung is all burned in from the local tv station logo during the morning snews.
Recently I had to do a similar repair on an old Vizio TV that had lost the back light. Two of those SMD capacitors shorted and caused the fuse to blow. Those capacitors left a huge carbon hole in the circuit board but removing them and replacing the fuse fixed it. That TV probably shouldn't have been saved since it was a 22 inch 720p with a scratched up lg panel much older than the TV from the factory but it was still an interesting repair. Those older plasma TVs were great though. I have an old Sharp from 2006 that's still going that just has a washed out vertical line that comes and goes in the middle of the screen. I wouldn't consider fixing that until the TV completely gave out though. I'm pretty sure it's a bad solder connection on one of the BGA chips as the TV lost half of it's picture for a while then just started working again, leading me to get a new TV for daily use.
technical question for you! Never come across this type of resistor color black at end. so orange being the first colour, then white, silver then gold but then there is a black band after the gold is it some kind of another tolerance band?? any clue??
Too many. Had this been a paid repair I would have probably charged 150 to fix this. The video runs only what 25 minutes, but it actually took me about 4 hours to find the problem, but as I showed in the video, only 1 part was changed. I showed all the steps in servicing, but spent much time studying the schematic on the computer, and I tell you this is a bloody complex circuit.
@@timka880057 Well I look to see if it can be fixed. When I was in the business everything was component level repair. No boards available, except for zenith. They used modules but we preferred to repair those too. I certainly don't miss those days.
@@12voltvids When I was a kid I loved watching an old tv repair guy replace compnents under the chasis of an old RCA color TV my brother had. It was very interesting in those days to see it come back to life again just for a few components replaced. I remember it was some old carbon resistors that was open or changed value... or a shorted capacitor and a few old tubes replaced. I miss that!
I have almost the same TV from the following year, even the same size. I also don't want to get rid of mine. Gonna keep this video handy in case anything happens to it.
Hi 12volsvids, great work as usual, I think it a little unfair for RU-vid to mind when you are repairing a TV to have a problem just showing it works, what if you didn't have your own stuff to show, I think it's a little wrong, truly awesome repair great work as usual. from Jim. 👍👍👍
Finding a silicon short can be a bear... I have used the alcohol trick in the past to find the hot spot where all the current is going to. That may have been challenging on this one given the low on time. Good thing is was just a crappy SMD cap. One failure mode on those is the cap actually physically cracking due to strain from the PCB heating or flexing; a problem in the larger caps. All in all a good find! Cheap at the cost of some time and one cap. Cheers, - Eddy
To find a short like that, you give it power from an external current limited supply. Then you look for hot spots. Alcohol works, or freeze spray, or IR camera.
i repaired a few TV's in my time. recently repaired a 24inch LED HDTV that had a diode short replaced them all as they were in parallel. ive also had a 42inch for repair that had bad mosfets, everything is made so cheap nowadays but its nice to keep something out of the landfill and fun fixing stuff. ive got a motherboard that has bad caps so will also replace them.
Well there certainly isn't any money in fixing stuff these days. I actually like the older stuff better myself. I like plasma tvs just because the science behind what makes them light up is so complex, it is actually cool. LCD is boring. Plot an X-Y coordinate and apply a voltage to stimulate liquid crystals to change polarity. Yawn. Now plasma you are talking science. Prechare the panel, select the line and apply a firing voltage to create an electric discharge. When you fire that discharge in the timing cycle determines the brightness. Then extinguish and charge to prepare for next sub frame. Do that 600 times a second.
My 50” died 3 days ago after 14 years of service. My wife is happy as I said I would buy a new smaller set. I am a retired electronic technician that worked on pc boards at the component level with and without schematics. Where did you find the manuals for your project? I might try to fix the beast and put it in my shop if I can repair it! Thanks for the video.
One thing with the Panasonic set is removing the screws that hold the set's back in place a 18 Volt battery drill with a adjustable clutch goes a long way to remove and replace the screws. Great also for removing the screws for the boards in the set as well. I used my drill every day and it realy saved your wrist and hands.
You poor little thing, having such weak little wrists and hands must be so handicapping. You realise that holding a drill to unscrew results in exactly the same amount of force being transferred to your hand? Then you must add the weight of the drill, which is adding extra work for your arms, wrist and hands!
I love Panasonic plasma TVs I have a 65 inch plasma TV from Panasonic and 46 inch Panasonic plasma TV. I love them both the movies or TV shows whatever you watch will be so enjoyable and the surroundsound that’s equipped on all these TVs. It seems like the sound is coming through the TV screen, very cool what Panasonic did everything the Panasonic makes is pure delight of enjoyment I will never get rid of them. I don’t know how long a plasma panel will last how how many hours does this lost my 65 inch Panasonic plasma I purchased 2009 and the other one 2012 so I really don’t know how long you could watch a plasma screen before it decides to burn out
Love the Viera TV's. I just had to order a new A board and luckily I found a new one for 100 bucks. Ran that TV hard for 10 years. They suck a lot of power but the picture is unequaled.
Ah, a late model Panasonic plasma - should be well worth hanging on to (substantial power consumption aside). They finally started using shielded panels in '09, so these should no longer be crapping all over the AM bands like the older ones did. Plasmas were a real plague - they would be directly radiating through the front of the panel, wreaking havoc on mediumwave and lower shortwave for quite a distance. My parents used to have an '06 Panasonic 42" 720p - great picture (these tend to have superb contrast), but it sabotaged my shortwave reception about 8 meters away pretty good. That one was reasonably power-hungry as-is, the 1080ps tended to be around 500 W if memory serves. Oh, and of course ceramic caps don't short _for no good reason_ ;) - usually it's the formation of microcracks caused by large temperature gradients within the part (easily generated e.g. during hand soldering), followed by silver migration through these propelled by applied voltage. I would tend to stick with automotive grade parts (which are of different construction and, in general, a good bit larger) or even traditional through-hole disc caps.
I kind of wish Plasma TV's stuck around longer...seems like such a promising technology, though probably bigger and has more componets then a modren LCD panel.
How did you obtain the manual and schematics for that TV I also have a Panasonic plasma that is currently still functioning but just wanted to know should I ever have an issue thanks and fantastic video keep up the good work
We actually used to have a 37" Panasonic 720p set with DVB-T Freeview built in. I didn't know that size was uncommon! The sound on it was fantastic, also :)
37 was the smallest of the plasma sets and wasn't as popular as larger ones. Same with the 46. 42 was very popular as was the 50. The reason was there wasn't much of a price difference between the 37 and 42, just like there wasn't much difference between 46 and 50, so the larger one was more popular.
@@12voltvids Indeed, I think we initially chose it because of the reduced day-to-day power consumption over the larger models. Also, like a lot of British homes, our lounge is quite small, so it seemed to make more sense considering ten years ago HD content was not as prevalent as it is these days. Replacing a CRT before it made it ideal for what was (for us) mostly standard-def viewing back then, anyway. Oh if only it had been a full HD plasma like your one, we probably still be watching it! ;)
@@Oldgamingfart There are some pretty small pads here too. With the high cost of land here micro homes under 300 sq feet are springing up in lane ways. My place would have been considered pretty small a few years ago and it is 2500 sq feet.
@@Oldgamingfart I have a standard definition plasma in the work shop. Not worth anything so I just watch it from time to time in the workshop. I have a 720 that I use for the news in the morning. It is burning quite nicely from the stationary graphics. My 63 is relatively power hungry. I do like the picture and some will argue that, but they have never seen my TV room. One of the chairs is at quite an angle and an LCD looks like crap off angle. An oled would look great but that is an expense I dont need right now. Want to get a 65" 4k oled some day but as long as my 63 plasma keeps going I am keeping it.
@@12voltvids Yes it's a mixed bag here as well, and the new builds are not particularly affordable for young people which is a modern day travesty if you ask me. My parents' home is a semi-detached Edwardian house, pretty typical of the era - large rooms, but not much in the way of garden/ outdoor space. Mine and my brother's house (we're neighbours), are both mid-1930's built, and the exact opposite - smaller rooms, but huge gardens!
Having problem with Panasonic TX-42AS520B Red Standby light continues flashing like 2 seconds gap. Had this issue first time like 2 weeks ago when it was not responding to remote and then tried from the power button on TV and first few times it did not worked. It tried to turn on green light flashing then green steady light and then red flashing light again but after few tries it did came on and was working fine untill now it happened again doing same thing. If I press power button on TV it does cone on, sounds is there screen flashing white colour 3 times with 1 or 2 sec gap and after 3rd flash it cutts off continues red flashing light. I have done all the basic like turning off from mains from mintues to hours even over night but still the same. I dont understand why it would start with flashing light when powers been off and when you turn on it should be standby atleast then but no so something its reading faulty even after restarting without trying to turn on. I am very technical minded and gets my hands on anything and not scared of opening and fixing anything and did few TVs as well in the past. Just needs right direction. Is it the power board I am looking or main board. I will be happy if I can fix the current ones if not changing board should fix it. I have got VOLT Meter if it needs checking voltages and Soldering Iron as well some where. Sorry for long message I like writing in details. Any help will be highly appropriated.
I have this TV but it is a 50" Model TC-P50U2 with 10 blinks. I have replaced the A Board and Power Supply Board but still get the 10 blinks and still don't get the 2 LED lights when powering on. Do you have any suggestions please?? Or does anybody have a suggestion?
I have a S1 series 58" plasma that had a one blink code. I took the A board off and found shorted capacitors similar to the ones that you found. I removed the shorted caps and re installed the board and on power up I now have 10 blinks. Voltages all come up for a second and then the set enters shutdown.
Hi great job you did very good I have a 50 inched Panasonic plasma that was given to me with the same problem as yours I plan on fixing it and keeping it my name is Roger Anthony Ash great job.
Lp was never a recognized speed. Only sp and ep. Lp typically used the narrow ep heads and there are gaps between the tracks. Even a slight alignment error will cause auto tracking to have issues.
12voltvids thanks! Do you think that replacing the AC head solves the problem. The drum is completely cleared. I'll watch a video in your channel about vcr alignment
Amazing tutorial. Thanks a bunch. You give so much value. I have the same issue. But a tv rep guy didn't diagnose that board properly. Since the conclusion was: There's something about the main board. What do you set the multimeter to? And does the tv has to be on for the device to beep?
I have a pioneer kuro 50" still working quite well. There's a buzz probably coming from the power supply but it's barely noticeable. Picture quality is better the any LCDs.
Pioneer had the best plasma sets. No question there and the were also the most expensive sets compared to other brands. When they shut down in 2008 Panasonic bought the technology from pioneer, and incorporated it into the high end Panasonic models. I have one and it is beautiful. Power hungry you bet, cooling fans, check. Perfect picture, yup. Perfect blacks, absolutely.
Not sure if I missed an explanation (so if I did, my apologies) but what was the purpose of the capacitor that shorted since you were able to get the TV working w/o replacing it?
@@12voltvids Ah..... I see... that makes sense now. Reminds me when I was building a circuit for a project and the schematics called for two ceramic caps to connect from a +5v and -5v to GND and the stated purpose was noise filtration. Also, just remembered that they do that a lot on RC & slot car motor leads to mainly reduce interference on TV broadcast (mainly analog broadcast I believe).
I think I watched another video of you where the ground screws where loose on a Panasonic set. I was kinda surprised you didn't check them on this one.
No I do very little. Water change every few months. I have a bucket of fresh water with a pump and float control to top up the water as it evaporates. I fill the bucket about once a week. Feed them every day and check / clean protein skimmer. Once established they are no more work than fresh water other than mixing salt for water change.
Hey 12voltvids! Awesome clip! I have a simialr fault right now - it seems! 10 blink red LED. I have NO idea about electronics - just following your steps! Now, I have only a cheap Craftsman multimeter without a beeper. My ceramic cap shows about 1800 ohms one direction and about 520 in the other (on the board) - does this anything?? IF I need to change that cap - is there any specific size?? My TV is a Panasonic TC-P42C2 version, the A-board looks identical, the power-board slightly different but the 15V points are all there - pulling the 15V pins one by one from the plug that supplies the A-board, with the 3rd pin pulled the 15V holds a second and then reducse on the P-board upper corner 15V point... So - I would like to know what this ceramic cap would read on ohms when in working order - what would it read if it is faulty? My ohm values don't seem to be high at all.... Appreciate if you had a tip or two for me!!
Thanks for the great video. I’m working my Pana 50 plasma with 10 blinks. When turned on neither voltage lights go on on the sustain boards. No voltage at the D351 spot. No 15V at P11 pin. Replaced P board and no luck same situation. replaced the A board. Same situation. I i found too if I unplug the left sustain board, the green light comes on the right sus board and the set clicks off to 2 blinks. You mentioned that because you had both green lights it meant that your P board was good. Any suggestions appreciated. Thanks much.
Dave. I’ve seen several videos on another site where shorted SMD caps simply aren’t replaced and the device works fine. Also open resistors are replaced with a piece of wire. If these fixes work , and they obviously do, what’s the purpose of the original, now defective, components?
The SMD cap is not required. It is just to filter ripple, and is more to help stop the TV radiating and causing interference to AM radio. The SMD resistors you see jumped are 0 ohm jumper chips and they can be safely removed and a wire placed in. If it were a real resistor, 10k 22k ect and you put in a piece of wire you would be asking for trouble.
Yes I have a 50 as well. In my panasonic collection I have a 42SD, a 42 full HD, a 42 THX certified 1080p, this one, and a 2012 50" 1080 set. I also have a 50" panasonic that has a seperate tuner box but that one is not fixed yet. Other plasma sets I have are an 720p 42 LG, 720 50" samsung, and 1080 FHD 63 samsung. I have 3 more samsung plasma sets that have panel problems (vert line or 2 in the screen)
@@petenamlook18 A back vertical bar approximately 1" wide is usually caused by a connection between one of the FPC tabs and the C board along the bottom. It could be caused by a bad drive IC on the FPC as well which is non repairable. A single vertical line line (black, red, green or blue) is a failure of the drive IC on the FPC that corresponds to that area of the screen, or the panel itself. Single line failure requires replacing of the panel to fix. 1" wide might just need one of the connectors restated. If it is a horizontal line it could be the a connection between one upper or lower buffer and FPC on the left side of the screen looking from the back. Or it could be one of the buffer chips on the buffer board. If it is on the top half it would be the upper board, and lower half the lower board. I have a total of 11 working plasma screens. 2 of them have single vertical line failures which is the panel. They are used for gaming, and an advertising display, and one has a small crack in the glass, but the set still works and I watch that one daily on the news channel so it is getting a real nice permanent burn it from the TV station logos and news ticker. Out of all those TVs I watch 3 regularly. The 2 with bad screens are used for gaming and digital signage, and the rest are sitting at the back of a closet awaiting the day when I need to put one in service when one of the others breaks beyond repair. I got all except the first 2 for free. I have had many more, but I do sell my spares for those people that want a plasma. There are people out there that seek out plasma TVs now that they can't buy them anymore.
I have 4 Panasonic plasmas... 50in.. I wont purchase any other TV but a Panasonic.... Their plasma line are true work horses... I had one 55-inch that stayed on for 3 months straight without being turned off.... The only thing that ever happened to it is the asshole Comcast guy reconnected the television straight into the wall saying that it would be a better picture... 2 days later an electrical storm fried my HDMI 1 and everything that was plugged in there after.... Laptop... Passport external hard drive... And a crappy MP3.... All because of Mr. Xfinity... Of course they would accept no responsibility..
Damn, I have 50inch. that has the same error code and problems, I'll follow your troubleshoot solutions, hope I find it! Otherwise, I'll just replace that board...
A Panasonic plasma that didn't have shorted IGBT's on the SC board? Whoa. Nice find on that shorted SMD cap. I think you should treat yourself to a second soldering iron for plucking SMD parts off. Me & my buddy have saved about half dozzen of these Panisonic's from the land fill. But first time I've seen a short on the main thumbs up!
@@12voltvids Yes it's strange the screws are always loose. You have a knock off hakko T12 station now right? Those things are up to temp in like 12 seconds. I have two with a bunch of different tips. Love em.
@@jeffescortlx Yes that was a problem. Panasonic came up with a service kit for the 2012 models that included new screws with lock washers. This set the screws are set with loctite, so these ones won't be a coming loose.
Dave, Thanks for the lesson. I see that your set consumes up to 331 watts of electricity. Do you watch it enough to notice a difference in your electricity bill? I've also heard that these plasma sets can put out a lot of heat as well. Is all that heat a problem or is it a problem that is over exaggerated? Regards, Tom
@@12voltvids Thank you for the quick reply. What I always wondered is, if you're watching a plasma set as your main TV set, would raise your power bill substantially?
At a rate of 0.12 per KWH running this TV for 3 hours would consume just under 1KWh which would cost .12 so about .04 per hour to operate. Our electricity here is .08 for the first 1360 KWH in billing cycle and then just over .13 for the rest of the billing cycle so no they don't cost that much to operate. All the wall warts, phone chargers, modem, cable boxes and all other electronics in standby 24 hours a day uses more.
@@12voltvids Dave, Thanks a lot for the detailed answer. One thing I've always appreciated is that you've always taken the time to answer my questions completely and thoroughly.
I have the Panasonic TC-P50GT30. First it had the 7 blinking lights. Got the TNPA5335 repaired and installed it 9/29/2020. Now the TV is blinking 8 lights. Any suggestions?
@@JohnSmith-wj4sh Pretty much. Check your connections on the boards, but plasma are complicated beasts. I have fixed a number of them, but even now I am leaning away from any and all TV repairs. The price has fallen so fast on TV that they are just not worth spending any time or effort on. I don't know that I would buy an OLED set though, due to the burn in issues. The SS board is a common point of failure for the 8 blink code. Here is one I had. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zYoxAqaKoBw.html This is my set, and it still works after I rebuilt the SS board.
I agree. Sure the old plasma sets use a little more energy, but the picture quality is worth it. When OLED becomes affordable that will be the next option, but right nw only LG makes the panels. Even the sony set uses an LG panel. There is a new type of LED that uses direct LED diodes not organic diodes. The trouble with the organic types is they are prone to burn in as they still rely on phosphor.
I had a customer that had a 50" Viera, fixed that POS 2 times in 2-3 years, first problem power supply module Panasonic must have had so many failures with that board and needed them so badly for rebuild I had to send the old board to them within a certain time period or I would be charged an additional $100.00 dollars core charge. I usually try component level repairs but not with that nightmare designed PCB. The second time it was a short on the tuner/signal board that I could not find I just swapped it, and advised customer to get rid of it. I asked him if he ever noticed the power consumption of that tv , he asked why, I told him it was almost 700watts about twice what an old all tube color TV took, he then knew why his electric bill was so high.
Panasonic initially had the module swap program because they felt that most independent service shops did not have the ability to repair them. When I took the plasma course that Sony had we were only permitted to repair the power supply, analog signal boards and audio amp board. They wouldn't allow us to repair the sc, buffer boards or ss, or the c boards. Back then the Sony sets were made by nec. Any failure of any of the panel drive board was serviced with a kit that contained all the boards and a new panel. Panasonic allowed only board replacement initially with the cores going back to Japan for analysis to determine why they failed. Early sets were power hungry but not the layer plasma sets. Also that peek power consumption is on a full white screen. Average power consumption is about 1/4 of that. My 63" shows 550 watts max. I have a killawatt meyer on it. On average 200 is all it draws. Yes it varies with screen brightness. If I was watching a hockey game naturally that is going to draw more but the average is 200 and when watching movies and such with plenty of dark scenes it is lower than that.
17:00 I can tell they had a Wii. Yeah, I remember a school I attended having similar model TVs for 2 dedicated Wii areas (but with only Wii Sports) they had in the hallway.
