My Toshiba (model;50HP66 plasma TV) picture and sound went out, but still seems to be on. It still has RED standby power light and will try to turn on with remote, GREEN power on light. The screen is black except for the edges arround the border of the screen and they are dark grey. If I push the MENU button, I can read the writing from the menu screen in the boarder areas of the screen. I have replaced the main board & power supply. Any ideas?
TV Technician: Michael Hannigan, Technician replied 2 years ago

Based on that, it sounds like the main board. BUT, it could also be a Y Buffer failure, which can cause YSus failure, which can damage the main board. So it may be something that started with the Y Buffer - when you changed the main board, did the symptoms change at all? Was the replacement main board new?

I got it from TVPARTSGUY. Used, But tested.
Customer reply replied 2 years ago
no, changing of the boards made no difference.
Customer reply replied 2 years ago
what are you thinking Michael?
TV Technician: Michael Hannigan, Technician replied 2 years ago

There's always a chance that a used part is not working... it happens frequently.

Have you tested the voltages with each of the sustain boards detached?

Ask Your Own TV Question
Customer reply replied 2 years ago
No, what should the voltage be?
TV Technician: Michael Hannigan, Technician replied 2 years ago

As you would have been instructed to do before.. test all of the power supply outputs (5, 15 vdc, Vs and Va) when powering up. They should each ramp up when you power up. If all of them are not, then it is probably still the main board.

If they ramp up but don't stay there, you should also do the same thing with each of the sustain boards disconnected.

This is something that you should have done even prior to replacing the main board. Did you carry out these steps before replacing the main board?

Customer reply replied 2 years ago
No. My new meter should be here tomorrow. I was hoping this would be as simple as swapping out a board. Not so lucky. Thanks, ***** ***** up later.
TV Technician: Michael Hannigan, Technician replied 2 years ago

Ok. It will be - once you find out what board.

I would appreciate a moment of you time to rate my level of service at your convenience. It will not affect our ability to communicate.
