So, I’ve pulled the Y-Sus board from the Vision PTS-4241 Plasma TV – this is the presumed faulty board (the symptoms are apparently quite common: Sudden loss of vision with functional sound).
Apart from the FMSD102A module (which may, or may not, be dead – and for which I’ve found a variety of companies in China who’ll ship me 10, 20, 80 or more, and for whom a minimum order of $250 seems not uncommon. I’m hoping to find a source for *one*) there are some capacitors on the board that look highly suspicious (at least to me – for whom a vision of bulging capacitors is a vision of death) – and there’s a few of the same brand on other boards that look similarly unhealthy. So I’m thinking they need to be switched out.
It certainly looks like the FMSD102A has got quite warm at some point, although how to test it I’ve no idea. Also, the report I’ve read suggested that four of the surface mount resistors tend to go ‘phut’ at the same time – and they *look* okay. I’ve not attempted any kind of measurement of resistance because they’re teeny tiny surface mount gidgets and my voltmeter is, well, vague at the best of times.
I’m thinking I might been needing the expertise of John for them, but it all hinges on getting this FMSD102A module. So here’s hoping, otherwise I guess I’ll try and get a replacement board, but then things get pricey, and I’ve no idea if the thing works…
Anyway these are the offending caps:
