Just want to let you know that I love your videos, and I let the ads play through. I learned that from one of your other videos. I learn so much from you!
I have a question about my Panasonic TC-P42C2 LCD. I notice that on dark shapes or outlines, there is a faint horizontal line protruding form the outline. It is really noticeable against solid colors like blue or green. I think it might be a banding issue, but I'm not sure. I have pictures to help reiterate my point if need be.
I saw you have a German tv station (SWR BW) running on it. Thats cool ;-) I also like your repair videos a lot and you already helped me to change a bad belt of the old VHS vcr from my parents. Cheers.
+Manuel Dibarbora I have hundreds of live performences playing on a media player. They all were downloaded from youtube. Currently I have about 425 full length concerts, Rock, Blues and Jazz from some of the greatest jazz fests in the world. They play out in random order from a Raspberry Pi running OSMC and into an MTS Stereo modulator and then out onto my house cable.
That's a dam shame as the rest of the tv works fine. . I was thinking about a heat gun or similar to see if it can be reflowed, but that depends on your interest/time and if its a compatable method. If it was a common screen i would put the set to one side with a parcel label stating the screen type needed, but i bet its an oddball job. Thankyou for making excellent electronic repair videos :-D, most people are not as good as you are, ive not found many real repairers like you, you make any repair interesting ;-D
Funny how people think you can repair anything ! That's certainly the case with me. I had a similar thing a few weeks back, it was obvious to me that it came under "I'm good but not THAT good" LOL. That item, too, went to the dump. Both my tellies are old CRT types, one's a 90's Toshiba, the other an oldie from Sony, a KV1330 Trinitron. Don't want LCD ones thanks !
+River Huntingdon Well this one I was hoping that it was just the broken power supply board, but no, the panel was damaged, so I gutted it for the boards and sent the glass off to the recycle center. I don't have much patience for LCD Tv. I will spend time on a Plasma because I think they are cool, and of course CRT sets. I have an old 9 B/W CRT based monitor that I use as a clock. That's right. I have an app running on a Raspberry Pi that generates a flip clock, and outputs it as a standard video signal.It is old as the hills, and I am just going to run it and see how long it goes. The tube has some nice burn in from back when it was a security camera monitor. I look at it as a badge of honour to burn in a CRT. One of these days I will dig out my old Tektronix broadcast monitors and overhaul it.That will be a good one to show off Jitter, and VITS and Macrovision ect, as you can actually see it on the screen when in pulse cross mode.
For someone who doesn't have a screen, that broken one was sure more functional than nothing. I would have loved to have had it as is for use as a monitor for a Raspberry Pi. I would just make a window smaller than the screen and drag it to the good part. Question: could a panel like that one be cut in half? I noticed it had two tabs. Could it possibly have been made into two smaller working panels or even one smaller working panel? Just curious.
Never worked on a LCD set before. But I remember my old teacher's warnings on very high voltage when tinkering with ancient CRT tvs. And I think LCDs are much lower voltages, but subconsciously I am getting the creeps you touching a live device. LOL. Guess teacher's warnings fully ingrained in me.
+alfblack2 Well first and foremost, my bench is isolated from mains voltages. Secondly I have safety training. I know where the hazardous voltage are. I work on tube gear too, and those operate at very high voltage. My favorite equipment to work on is hifi audio components, Dat tape decks, vcr, cry TV, an plasma TV. I don't like Lcd TV or cameras. I just rebuilt a Panasonic sv3500, Dat recorder. What fun that was. The video will be done soon.
Hi...How are you Sir!!!! Have a SAMSUNG LA26RT1B LCD with T-CON 260W3C4LV0.0 (Panel : LTA260W2-L13 Samsung), the problem is thick white bar about 3/4th from bottom, only signals TP on T-con Board is CPV1, CPV2, STV (not finding the CKV TP points), can you kindly help me with guidance for trouble shooting...Many thanks in advance!
I wish a manufacturer would produce some way to make those driver IC's replaceable. Early plasma panels were like that. Later they made buffer boards replacement easy in plasma for some manufacturers
That won't happen. Early plasma were 852 x 480. So 852 conductors on 1 plane and 480 on the other. On a large panel it was possible to have edge connector with that many pins. LCD now 3840 on one plane and 2160 on the other. Not gonna happen. And early plasma did not have replacement ic. When I took the plasma course in 2001 there were no buffer boards. Back then all the buffer chips were part of the panel.
I’m in hopes they will follow the commercial market on that as it’s out there just not in the hands of the public yet. It’s being done on some displays UHD type on aircraft. The connectors snap together tabs but require a microscope to align the ribbons. And the LVDS signals are the same as Used on TV TCON boards. Xtron Corporation has a test jig to drive the TCON we test with and I often drive TV panels with it for test.
If the IC is hot-bonded, is there a chance that you could warm the connection to re-bond the IC? I just used a heat and stick technique to fix my select number bed remote. It involved heating it up and pressing on a thin ribbon a few time. My whole display is not w back.
+Tech Gorilla Possible, perhaps. I give up much easier than that. Besides the guy that owned it is a pain in the ass. I would never hear the end of it when something else broke. I sold him a used TV a few months ago, and am regretting it now. It is one thing after another.
+12voltvids Understood. If that was the case with me, I would do it for the learning before scrapping the carcass. I have a couple of Sony pieces I just picked up for free. I have an SLV D380P and I have a CDP-311. You think there is still a market for these?
I was thinking the whole time: put the magical heatgun on it :) I see a few commenters think alike. I hate the fact that anytime you reduce the problem down to some hotbar attachment it's basicallly game over for a home gamer. At least you went through a great deal of effort to save this set, do you let the owners know you've made a video about the repair? If so, are they interested? Thanks for the video, as always!
+Koffi Banan The owner saw it. He keeps bugging me for TVs. I tell him all I have is plasma. He doesn't want plasma because LCD have a "superior" picture in his eyes. Really? I never saw an LCD that I could watch.
+Chi Chu This was more of a tear down. I wasn't expecting to fix it, Most LCD failures are lost causes. Plasma are very serviceable, but LCD nope. Throw it away and send more money to the PRC.
