Re: Panasonic TC-P50X3 Totally DEAD

So is the general consensus the A board is bad? Anything else I can do to verify it's bad?

And does anyone know where I can find one of these? I've looked all over and everyone is either out of stock or wanting more for the board than I paid for the TV.

According to the manual the part number is TXN/A1PMUUS.

Thanks,
Rob

Re: Panasonic TC-P50X3 Totally DEAD

Thanks for all the suggestions. Sorry for the delay in responding but I had a pretty big callmanager upgrade at work I had to attend to. I have finally been able to determine I am getting +5V to the A board on STB5 (A6 - pin 6). I have not been able to detect anything going back to the power supply on pin 1 (PANEL_MAIN_ON).

I was not quite able to follow the Tom66 thread about the AC detect. Is this MC Module on the A board or the P board?

I guess it is looking like the A board is toast but I have not for the life...

Well I dug out my trusty DVM and here's what I've found.

I am getting 120VAC to the board and across the fuses.

I get nothing out of the power supply board on any connectors (P11, P2).

Checked P6 from the A board (A6). Nothing on P1 (PANEL_MAIN_ON), P2 (P_S1), or P3 (P_S0).

Not sure if I got a bad replacement power supply or what at this point.

If pictures would be helpful I can take some, just not sure what specifically you want to see.

Thanks,
R...

Now that I think about it, you are spot on. It came in through the cable which explains why it took out the TV, Cable modem and DVR....

Awesome. The service manual will be a big help. I'll do some reading and research and get back. Thanks for such a quick response....

I have a 2 year old Panny TC-P50X3. After a nasty storm went through our neighborhood, and I believe the house may have been hit by lightning, the TV no longer powers on. At the same time, my cable modem fried and my DirecTV DVR. The Panny was on a surge protector and nothing else on that protector took a beating.

I get no blinking lights. I get no lights at all. I hear no sounds or clicks. So I figured perhaps it was the main power supply board. I have replaced that board but still I get nothing when I plug it in and try to turn it on.

I am relatively electronic...

Hello from Peoria Illinois. Just trying to fix a 50" Panny that won't turn on after a nasty thunderstorm rolled through. This forum looks like my best chance.
