i have a Philips Plasma tv model 42PF9630A/37 with top half of the screen black...i suspect it will be the upper y-sustain buffer....but could the main also be bad??? if the bottom half is still running ok, would you suspect the y-sus main is still good or no??? is there anyway to test this??? i dont want to have to replace the main if it doesnt need it...thank you very much

Re: philips plasma half screen
This TV seems to use the LJ92-01200A / LJ92-01202A / LJ92-01203A set of boards. It is almost unheard of for a Y buffer to fail without taking out the Y- Sustain (Y-Main). Maybe you got lucky. The question is: If you spend $70 and the the other two boards fail, taking the new one with them, is it going to be worth it?

Re: philips plasma half screen
I have a non-working Magnavox 42MF230A/37 with these boards that apparently needs the buffers and sustain repaired. Replaced the power supply and have all voltages up to par but no picture or sound. I'm unclear as to what Coppell TV is offering when they repair the sustain/test the buffers? Do you know if they also repair the buffers or would they have to be replaced? Do you do any component repair?
The cost of new buffers would make it not worth it...TV is a 2006 model.
Is there any way to test the plasma panel to make sure it works?Comment

My Panasonic Plasma model P55VT50 has started displaying "interference" on just the left half of the screen only (left when facing the screen). Sometimes it's concentrated in about the first 30 seconds after startup, then disappears. Other times it's fine at startup and then randomly does it later on. When it flashes the interference it's very quick and doesn't stay on the screen unless it flashes repeatedly in a row.
This image is a screen shot from a video I took. This is an example of the interference at its worst. Often the interference is much smaller...10-14-2022, 04:54 PM -
Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same... -
Hello guys.
I recently got a TV that has the following problems:- Sometimes it has to be turned on and off a few times, to boot up. Sometimes it starts from the first try
- When it is running normally, the right side of the screen flickers. Sometimes it is just a square of transparent white maybe a 1/3 of the right half (top right)
- The flicker is also sometimes a square that is filled with lines
- I noticed that when the TV brightness is set to max, it flickers less. I think the Standard setting is the worst where it comes more frequent
- When it runs a few minutes it gets better,

Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen... -
The 55" LG has been in the basement for a few months without being used. Turned it on yesterday, set came on as it should and showed a complete screen for about 5 seconds (was on a broadcast channel but no antenna was connected), then the screen went mostly dark with about 1/3 of the screen on the right lighting up with brighter lines in that lit part (sorry, no pictures of that). Power LED was cycling too, preventing the TV from fully powering up.
Pulled the back off, all boards looked OK. Pulled the LED connector, turned the set on to see if it would power up but I don't belive it...
