What's inside a TV, i cover what are the correct volts you should be reading on your volt meter, a troubleshooting repair service guide to help check / read voltages using a volt meter, this is a Samsung Plasma 50 inch TV. power board stby pin should read 5v on the multimeter 5v going to main board whether TV is on or off even if TV doesn't turn on you should read about 5v on your meter, if not replace power board, for "TV repair" parts or "TV boards" at shopjimmy.com or electropartsonline.com use discount code - tampatecfriend
Common repair for Samsung TVs is no power check for swollen bad capacitors on power board and sustain boards. if TV has black bars it can be bad IC on buffer board.

@philipschlabs1929 4 года назад

Hey Tampatec. Yours are my favorite instructional tv repair videos. I have a question on plasmas though...I tried troubleshooting my 60inch lg plasma. It just clicked on and off, then on and off. When I took the back off, the board with the HDMI inputs had a red light that flashed whenever the clicks happened. Other videos suggest unplugging each board and cycle power to rule out the bad board. It clicked the same whether it was connected to one, some, all or none of the boards. I did my best to check voltages. No wonky caps. Seems like this is power board, yeah?

@jefft.4554 7 лет назад

I'm troubleshooting a Pioneer 503cmx plasma. The set does a Power Down (protection ckt shutting down the PS) shortly after the relays click on . It will stay on if I disconnect X & Y sustain boards from the PS. Looking at PS, all the low voltage supplies are exactly where they should be. VSUS is 224V, but any test points marked "0V" on the PS board are reading -52V (to chassis gnd). No obvious signs of burnt parts and no bulged caps. Ideas on where to look first? Also, would this failure be confined to the PS or would it be likely that it damaged other boards/circuits as well? Thanks so much for any input you may offer!

@QuentinCarter1975 4 года назад

@patrickgreen2714 6 лет назад

Thanks for all the informative videos. It's great that you want to help others. Are plasmas really going the way of the Dodo ? I have one thats seven years old and it just lost the picture . I don't know if it's worth fixing or to buy an LCD. What's your opinion ? Anyways, keep up the good work. Thanks for your help.

@TampaTec 6 лет назад

patrick green the problem with plasma TVs is you can fix one and it may last another five years or one month. from my experience fixing LCD TVs you fix one and they tend to last way longer.

@SporkSchivago 5 лет назад

Is there a reason you didn't adjust Va voltage? Also, do you know what acceptable tolerances are for the various voltages printed on the sticker on the panel? Va, Ve, VScan, etc? Is 5% of the printed value acceptable, or 10%? Thanks!

@vnosthas 6 лет назад

Hi Tampatec, I have a LG plasma tv model 50pj350 with sound but no image. I checked the power board and it is working, changed damaged mosfets on YSUS, caps read ok, so do resistors and diodes. Though the VY and VSC testing points shoud read -198V and 135V and I have no more than 60 volts on each. Any sugestion? I’ve tried to get the board diagram with no success. Thanks.

@danielsangels5753 7 лет назад

Hello Sir! very nice informative video! What if the 12V pin going towards the main board is not 12V but 11.8V? the TV is on. do you think the main board is at fault? I have 5V standby voltage both on and off state.

Hey Paul, I have this exact same tv . When I got it, It would not turn on and had a fast flashing red stby. light on the front.. I replaced 4 bad caps on the power supply and it did turn on and stay on with no picture or sound so I ordered 2 buffer boards. 2 weeks later I installed the buffer boards and when I plugged it in the stby. light was solid, tried to turn it on and all it did was the relays clicking on and off 5 times and goes into shut down mode. Unplugged both the Y and X boards, same click pattern. I am showing 10 volts on the stby. and 25 volts on the 12volt pins, also 10 volts on the vs_on. Is that still indicative of a bad main board?

@pm240sx1 6 лет назад

I have a Samsung Plasma pn51f5300afxza and the power board is shot. I see on the power board there are 4 different verisons of the same board. (P51ff_DSM, P60QF_DSM, P51FN_DSM, P60QN_DSM) My verison is the P51FF_DSM. My question is can i replace the board with any of these verisons?

Hi currently working on a 50 inch plasma. Standby light on. Power up standby light blinks goes off for a few seconds comes back on. Logic board? green led will blink 3-4 times then goes out. 120vac into full wave bridge rectifier but only 79vdc output. Seems low to me as expected 150-180vdc but I have no schematic. Any thoughts? Thanks

@Ziffel22 7 лет назад

I've only had plasma tvs since flat screens came out. My first one was a Samsung EDTV (Enhanced Definition) on 480P cable and 720p on DVD. Now I have a Panasonic TC-P50ST60 which cnet gave it's highest ever rating to for a television. Plasma TVs are the superior format but everyone is going towards LCDs. Too bad but I hope that my television will last the rest of my life.

@VideoAmazed 2 года назад

The video was very informative, but it doesn't address the particular symptoms that we are experiencing with our Samsung 42" HPS 4253X/XAA. This Plasma TV has been installed on a TrippLite HT-1000UPS to eliminate power brown outs and surges and has given us very reliable service. The symptoms ONLY appear at start up in the morning. The entire screen is dimmed but the channel chosen is still visible but is grainy and the entire screen slightly pulsates for about 5 minutes and then the screen cleans up and then appears normal. I presume it to be a power supply related issue ? Possibly an electrolytic weakened with use ? The TV works great otherwise and I hate to discard it without trying a simple fix. Your feedback would be greatly appreciated. I'm a Ham Radio Operator since 1966 and have experience with soldering and circuit repair, but not much experience with flat screen repair ?

@jessecastaneda7982 3 года назад

On my plasma tv im good readings on the va and the vs but low reading only 3 volts on the 5 volt does this mean ps board is bad

@patrickmorrissey2271 7 лет назад

High end plasmas had amazing picture. I seem to recall some states/jurisdictions were talking about banning them, because they suck power like crazy. So I think big screen TV makers kind of just said yeah okay, let's start moving towards LED/LCD type of big screens.... That's a good video. You can find these plasmas for nothing these days.... Can you still get parts?? Is shopjimmy supporting these at all???

@vernonperez9482 3 года назад

Hey TamaTec, it's Vern in Clearwater. I have a Samsung Plasma PN64D8000FFXZA that has no problem at all with the picture image/quality. The picture does however shut/click off on its own but the power seems to still be on because the green light in back blinks with a solid slow intermittent blink that seems normal and the red standby light is not illuminated as if it was still on. At this point I can not get the TV to respond to any command (The standby red light does flicker when I push the remotes buttons) accept it will turn off if I hold the remotes power button down for 3 or 4 seconds. At with point the standby light does illuminate red indicating it has power. It will not turn right back on. After letting it sit for half an hour or so, it turns back on and works completely normal for 5 to 20 minutes. I tried bypassing the APC UPS and using just a DVD, but it will still cut out. I have looked up the cost of the power board and main board and found them for around $40 each so I was thinking about first the power board, then maybe the main. What do you think?

Hi! I have a samsung plasma tv PS64F8505ST (the last plasma of their high end tv models/ 2013 European model) I would apreciatie the help from you about my issue. Last year i replaced the Y-susboard due to no picture. This time my tv turns of about after 30-90 minutes. Everything just shuts of, even the led light. Cant turn on the tv with my remote even after i replugg the cord to the outlet. I thought the problem sat at the X-sus board. I tried switching to another x-sus board but the tv wont even turn on or show any picture. The power board starts to "clicking" instead so i unplugged the x-sus board from the powersupply and the "clicking" sound went away. When i switched back the old x-sus board it worked fine without any clicking sound from the powersupply but the tv starts to turn of again after 30-90 minutes. I had the powersupply get a light inspection (just looking after any visible faults) but the guy said that he didnt se any problem with the board. What do you reccomend me to do next? Best regards

@hansawr 5 лет назад

Hello! First thank you for all your videos. I don’t know if you will read this but I will give it a try, I also noticed that the video is 2 years old but I’ll take my chances. A neighbor recently gave me a faulty 60-inch plasma TV, the exact model is PN60E5300AFXZA, when you plug the power cord the stand by red led comes on, and when trying to power on the tv it will blink a few times and nothing else happens, no sound, no nothing on the screen. I took the back cover off to check if I was able to find any visible indicator of a bad capacitor or any signs of a damaged component. Nothing visibly damaged. I tried troubleshooting it by unplugging the cable that goes from the power board to the X Board (Right side of the tv) and to my surprise when you try to power on the TV this time you hear the power on tune, a sound! but no image and the TV goes back to standby mode.Voltage in the PS-on is correct and also in the Standby pin. I just want to know which board would be the culprit in order to find a replacement… Can you give me any other ideas on what to test to pin point the faulty board? The Y board gets power from the X board, so I unplugged just the Y board and no sound no picture. When the X board is unplugged, power on sound, no picture, and goes back to standby. Do you have any advice on what should I test next in order to find the faulty board? Thank you very much in advance.

Possibly x or y sustain boards. Sounds like x but possibly both. Get tv boards at shopjimmy.com or electropartsonline.com use code tampatecfriend for discount.

Thank you for your message. And what would be the proper way to test the power board? Do I need to short the ps-on and 5v sb together? or just the ps-on to a ground pin? Thank you again.

Hi Tampatec I am having a real problem plasma tv it is a LG 42PT353K. Now the power supply is fine for voltage with no boards connected to it. When i connect the main board the standby voltage is low it should be 5v and it is 3.45v.When i connect the x board tv clicks on then clicks straight off, so i changed the x board and it`s the same problem. Now i need some help with the logic board. I have been told to check the main board i need to solder a wire to it to test if the tv comes on.Any help would be grate for this trouble shoot. Cheers man.

Jim Dailey I have a Sony 65 inch projection tv which keeps blink ing the picture on and off. What's wrong with it? Thank You.

@mchammer256 7 лет назад

Hi Jim Dailey. I would just check no wires are not loose in side and out side of it ,and check the voltages are what they should be going around the board. But as i have never seen inside a projection TV it is hard to say. If it is using a bulb i would just take it out and reinsert it , if possible to do that. Good luck with it .

I wish I had kept mine. They don't have the common issues that a lot of led tvs have.

Pitbull, I think you're right. Bought an LED, beautiful picture LG HDTV for another room. It lasted right after the warranty - 2 fugging years. Life's Not Good (LNG)
