Re: panasonice tx42s31b 8 blinks

8 blinks -- SS board or SC board. Do you get an LED glow on SC? See training manual.



(for 3D model - maybe 2D model manual available elsewhere - should still be usable.)

Re: panasonice tx42s31b 8 blinks

The led looks like d583

Re: panasonice tx42s31b 8 blinks

I can't see any LED. There is a repair kit available which involves replacing all 7 surface mount FETs, maybe try checking them for shorts.

Re: panasonice tx42s31b 8 blinks

Where do I get one of them from ?

Re: panasonice tx42s31b 8 blinks

Perhaps try searching for TNPA##### (with ##### replaced by the numbers after TNPA printed on SC) board repair kit.

Re: panasonice tx42s31b 8 blinks

No green light after it goes off? Any panel glow?

[adamp91gvm]

Re: panasonice tx42s31b 8 blinks

Nothing like urs been turned off

[adamp91gvm]

Re: panasonice tx42s31b 8 blinks

Its*

[tom66]

Re: panasonice tx42s31b 8 blinks

So the green light does still light, no red flashes? I'd be hedging a bet on the A board. Maybe tw2005 has a better idea.

Re: panasonice tx42s31b 8 blinks

disconnect sn2, restart and see if that produces a blink.

[adamp91gvm]

Re: panasonice tx42s31b 8 blinks

Yes 7 blinks

Re: panasonice tx42s31b 8 blinks

Yes 7 blinks

Dead short on SN board I would say, most likely Vsus, sn2
