sw2056 (key3) is a momentary integrated on the A board

Ah guess since this is a cost-down version of other sets they omitted the main power on/off.
It was always a bit useless, it essentially only turned off the LED and reduced power consumption by maybe 10% in standby (0.35W vs 0.4W)

Anyway, since modus have a big sale on, $50-60 (after 30% off) for A board repair

P board on Ebay for $55 N0AE5JK00006

Re: Panasonic 42' Plasma TC-P42x3

Even though the chart is not 100% for this, I'd say if the 3.2v is there then P board since the A is trying to start the PSU, if missing A board.

Could always try isolating the SN and SS but I'm not confident it's them especially if it was working then not after a spike.

Wouldn't it throw an SOS code though?

Well you'd hope but you know with dead shorts on the PSu funny things happen like for example locked solid LED or 14 blinks .

The other thing is are we assuming S0,S1 are highs and not gnd which are switched? I know recently i made an assumption the K board LED was a high but turned out to be a low.

gut feeling this will be A board, just with 5v stby and relay clicks I wonder.

have a look at the 2011 chart, slide 33, does give the scenario of relay clicks, then expect A or P we can ignore K due to this setup.

best i can come up with

Re: Panasonic 42' Plasma TC-P42x3

So what I'm getting is that it's a crap shoot at this point? Anything else I can do on this end to narrow it down?

That's fine. If you don't want to play the game. I did ask for some info, I'll move on and help the next person and not waste my time here.

Re: Panasonic 42' Plasma TC-P42x3

I'm confused and did not mean to insult anyone. I thought that you ruled out the 3.2v check from your dialogue with tom66 and that there was no certain method to isolate the fault to the A or P board, hence mentioning a toss up or crap shoot.

4 mV on pin 1 when plugged in.

Re: Panasonic 42' Plasma TC-P42x3

best guess is A board and get it in to Modus whilst the sale is on if you want to continue down that path. If it turns out to be the P board, so be it. I've already provided some info on what's available and cost
