Replacing the Y Sustain board on a 50inch plasma tv Movie.wmv

A word of warning: A television has high voltage and can kill you if you touch the wrong part.
My two and a half year old 50 inch plasma is broken already. The Y main or sustain board needs to be replaced. The tv has no active cooling and I'm not surprised it overheated with the tremendous heat generated. Out of warranty repair will cost several hundred dollars. It's a shame they can make such poor quality products. All they needed was a few strategically placed fans to cool the tv. Don't attempt the repair if you are not qualified to do so. The residual electricity from the capacitors, even when the plug is disconnected, can kill you or give you a nasty shock. This video is best viewed on a PC showing the annotations which serve to clarify the locations of different boards and the connections.

Hi, Thanks for the video. I suspect my Y Main Sustain board is gone as well. Can you tell me what was the problem with your tv before you made the repair?

Thanks

@rakcochrane I had very fine vertical stripes of green and other colors on my plasma screen. Watch the beginning on my video. My older video on "Heat related problems with my plasm tv" also showed a similar picture. Maybe you can descrbe what your screen looks like and what your tv problem is.

@wtam69 Hi, Thanks for your reply. My screen is totally black. Doesn't even prime. TV seems to power on with the welcomemusic, but that's it. I've seen other videos where people also have this problem and it's also the Ymain or Y buffer boards.

@rakcochrane It could well be the Y main, buffer boards and possible the X board.

If u can check my profile I uploaded a video so u can maybe get a better understanding of wuts going on

@TheChill789 I saw your video. If the y board was your only problem, the picture should not be dark like that. You might have other problems like the buffer boards. A bad y board can bring down the upper and lower buffer

boards. This can be frustrating as you don't know exactly which other board is the problem.

[rakcochrane]

@rakcochrane Ooops, sorry. I see now what was you symptoms.

Thanks

@TheChill789 The image shouldn't be dark. There might be something else wrong like your upper buffer board. If the picture is just slightly off with some artifacts, then you might need to adjust the voltage. Better to find someone who knows how to do that since the tv has high voltage and can give you a fatal shock.

I changed the y main board like the video but now image is dark and when I turn on tv it has black spots that fade away as tv turns on
