Panasonic TC-P42S30: AB vs AD SN boards

[Capt.Blackadder]

I have a Panasonic TC-P42S30 plasma TV that went TU a few days ago. After following diagnostic procedures that I found, I've determined that the SN board has shorted out. Replacement boards are apparently in short supply, but I've seen a couple of used ones on eBay.

Before grabbing one of those, I thought I'd ask: Is there a significant difference between those marked TNPA5349-AB and those marked TNPA5349-AD? Mine is the AD flavor, and the eBay boards are AB. I saw in a sticky thread that "sustain boards are usually specific to a particular screen size", which leads me to believe that an AB board would work OK... but if anyone could confirm that, I'd be grateful.

They are but if they're fitted to the same size then generally the differences are very minor.

I would just get the AB, both were fitted to P42S30 and according to Shopjimmy data, the panel part number is the same.

Some reasons these boards get hard to find are, it's a weakness and plenty fail this board, most pull the old board out, put a new one in and discard the old one which is repairable and quite a few have successfully repaired these at a fraction of the replacement.

Point being is that Panasonic won't carry or manufacture boards forever. My 2010 FHD model, that board I have been informed is no longer available here from Panasonic.

So if you're unable to repair the board yourself, it never hurts to plonk it on the Ebay or ?? and sell it as a core for repair.

Thanks very much, appreciate the quick reply. An AB board it is, then, and hopefully that's all it will take to get that TV working again.
