Interchangeability of Panasonic Plasma TV A Boards

I have a Panasonic TH-50PX80U with a defective A board (mainboard). The s ervice manual lists it as part # TNPH0716ABS, but the board itself has a "2 A" instead of ABS suffix. I've looked around for a replacement, but can onl y find boards with the A, AG, or AGS suffix (the -ABS are all out of stock) , listed as fitting the similar model TH-42PX80U. So my question is, are any of these boards interchangeable? Will a mainbo ard from the 42" version work on the 50", and does the suffix or lack of it on the part number make a difference? Thanks for any advice.

If you look it up on shopjimmy it usually gives some interchange informatio n. In most cases when dealing with different suffixes if you can SEE the di fference it may work, if you cannot see the differences it usually won't. W hat I mean is that if all the workling plugs are the same but you see somet hing different like a plug for another side input, external speakers or som ething like that but everything else looks the same, the chances are good. If the board looks identical it is more likely to be a change that you can' t deal with.

Doesn't sound right , but...

A bit of further research shows that each of these boards has a different f irmware version, so I guess they are not interchangeable. Anyone have a good -ABS board they want to sell?

The firmware could be anything, how the TV information is displayed on the screen.

What you need to ask yourself is, "are you ready to scrap this tv set?"

ONce the answer is yes, then it's really about how much you're willing to spend. Since the tv set is scrap, any attempt at getting it to work is icing on the cake. You can't hurt it since you've already decided it willb e scrap. That gives you an edge, a willingness to take chances that you won't if you still see hope for the set. The only other issue then is how much you're willing to spend on a gamble.

Of course, in the internet age, it all becomes about "folk knowledge". "Anyone" can change a board, it takes more skill and experience to at least figure out what's wrong with the tv set. When someone can do that, they have a better edge on replacing the board, or may be able to fix the board itself.

But if you can only deal with plug-in solutions, then there's a very narrow window for doing much. Get information from others, and hope it works.
