My Panasonic Viera TX-P42S21B 42" 1080p HD Plasma developed a fault a few days ago.
It looks like it's going to come on, makes that click sound but then goes off. Doesn't turn on via remote.
So, obviously it's likely one or more of the components/boards. I don’t see any results for my model or a service manual anywhere, but I’ve briefly looked into it with similar models and apparently it is the SC and or SM board(s.)
How accurate are the fault blink codes? I don’t see any glaringly obvious damage on the SC/SM boards but the power supply has some markings. See images. Could the PSU be the original issue, causing this instantly happen again if I replace the SC/SM? Or am I correct in saying when an SC/SM goes bad it can take out the PSU too? How do I correctly diagnose everything?
I briefly spoke to a couple of part sellers, since they advise asking questions before buying.
Answers:
I asked the same slimmed-down question as this thread to two sellers. The first on a listed power supply and the second on a listed Y-SUS.
A) Hi, I have been advised that is a Y sus issue i am afraid. Many thanks, […]
A) […]Hi, yes this board will do but the fault can also indicate a problem with the X-SUS board and or the Buffer board too.Thanks[…]
They never brought up the marking on the PSU.
I don’t have a multimeter to hand and I’m a novice anyway. But I have ordered one for Sat. I will be looking more into it over the week until it arrives but any info/help would be greatly appreciated.
