Panasonic tc-p50vt25 problem, help!

[Ncdude]

Hi all,


My TV has started some strange behavior that I need some help troubleshooting. I turn it on and start to watch tv and then with no warning you can hear the tv click and the screen goes off but the red led on the front stays on and never blinks. Sometimes the tv recovers and has an error message "error occurred and was recovered" or words to that effect. Other times the screen comes back on and if you push the volume button on the remote it goes off or it recovers and sits for 20 seconds and goes off. No matter the behavior the red led on the front never blinks. I hope this is enough info for someone to make a suggestion. Very frustrating for sure.


Thanks for the support,

Scott

Yeah, sounds like mainboard(A-board) however this being a VT also has a D -board. I've heard of this before and also I picked up a 2010 U series with the same issue and it was the A-board I suspect heat and broken BGA solders.

If you did not have the D board I would say 100% A but I still think it's A but there's that chance I may be wrong. D failure I've read of 1 blink or coloured vertical blue and red bars across the screen.

Maybe drop PTS a line , they've probably seen it before and I doubt you'll find an A-board for less than $95 but I'd be as descriptive of the issue as you can especially if it's intermittant.

Thank you for the reply, I was leaning towards the A board myself and you are correct in saying intermittent. I definitely don't have any lines on the screen, it just stays black or gray until it recovers. I felt it was a loose connection or broken solder but seeing those are rather tough. I will start the hunt for an A board. If you think of anything else I will be happy to listen.
