SOURCE: Toshiba 42hp83 plasma power supply problem?

I had the same problem. It turned out that one of the cooling fans get dusty and does not work. I opened the back of the Toshiba plasma TV and cleaned the failed fan, and it worked like a champ.

SOURCE: I have a Phillips 42

I wanted to share my solution to this problem. Not only is it an easy fix (aside from taking the tv apart) but it also explains some of the strange methods I've read that have worked, such as taking out padding from behind the boards or putting a magazine under one side and even tapping on the tv for a temporary fix.

Granted its only been a few days of it working but I tell you this....It's not done the half black screen once! And trust me when I say it was doing it constantly.

Ok so first off the problem definitely lies in the upper/lower buffer boards. On the model mentioned by the OP (same model I have) it's located on the same side as the power button (right side when you are looking at the tv).

Ok so you've got the tv openned face down on a non static surface. Btw I was shocked at how many youtube videos I found of ppl working on their tvs while its laid flat on their sofas!

When you are looking into it you will see on one side there are two vertical boards hooked up to another board more towards the center. These two boards are your upper and lower boards that provide the upper and lower picture. The problem I was having was in the lower section of the tv going black so obviously that corresponded to the lower board. (They are labelled upper and lower if you look closely)
So here is what I did:

I noticed the lower board was not sitting flush so I unscrewed the one screw on the bottom and noticed how much of a gap was in the screw hole. The problem was it was screwed down in such a way that one of the connections going to the main board was not making it's proper connection. So I just gave it a little push towards the center, held it, and screwed it back down.

That's it! It's fixed now. No need for replacing anything. Just poorly drilled holes and a few things not lining up correctly!

So hopefully anyone else that's having this same problem might have some luck in using this fix. Good Luck!

I have this same problem with my 52 inch toshiba regza , The repair shop has said the cost of repair is as much as it is to replace the TV. I am past the one year warranty, but less than 2 year ownership, so Toshiba won't fix the known issue. Solution is don't buy a Toshiba

Picture is fine for about an hour then goes fuzzy


Hello Townsend, It sounds like a problem called blooming, or you are having a problem with focus control which are signs of a problem in the horizontal and high voltage section of the tv in the case of plasma TV this would be the excitation circuit. I would suggest that you take the set to a TV repair shop to effect repairs.

Ps 27123 have sound, tuning etc only small horizontal color band


Hello bdedrick708,

If what you are trying to say is that you have a 1/4 inch horizontal line across your screen, this means that something in your vertical deflection circuit has failed. This could be the vertical oscillator, the vertical output processor, the vertical coupling capacitor, or the vertical section of the yoke transformer.

If what you are talking about is a vertical line from top to bottom then you are possibly talking about a failed horizontal section of the yoke transformer.

Why so little about the horizontal section of the yoke? That is because if the horizontal section fails completely then you would lose high voltage and no line would be present because you would not have raster (screen light).

In any even check the yoke transformer first. Then work back from there.

I hope this helps,

Thank you,
