This roadside find was screaming "help me, the garbage man is coming tomorrow!"
So, I picked up this Panasonic Plasma 50 inch. It was full of dust but no smoke soot.
It has a 1 blink code which I understand from the downloaded manual, is an "A" board problem. Relays click and then, unclick.
Anybody have any experience with these? Thanks.

The mains are known problem children, and finding a working used one may just put you in the same boat in a few months.

IIRC, the problem was usually a bad/corrupted dram.

I stopped taking those in years ago.

UPDATE! Found a thread on Badcaps that discusses the 1 Blink problem . It was determined to be corrupted data from IC9304 which is an EEPROM. One poster did a swap from another board into a dead board and it worked!
IC9304 is available from a number of sources:

I have the same TV I picked up from a local comoputer store that also does electronics recycling, that it has a power supply issue it seems, mine is blinking about 3 or 4 times when you attempt to power it up.

Yep, 3 or 4 blinks is a power supply issue. There are fuses on the schematic that I couldn't find on the circuit board.
Here's the link to the manual:

Thanks, I'll definitely be taking a look at that manual, and see if I can get my TV going as its in pretty decent shape yet and doesn't seem to be a high hours set.

I heard that you can hold the button down for 10 seconds and it will show you another code, if you have one.
If your diodes check OK, I'd check the MOSFETs, or anything that looks like a MOSFET, for short.
I think the EEPROMs are all the same on those "A" boards for most of those boards of that design.
