Panasonic tc-p50x3 won't turn on

Re: Panasonic tc-p50x3 won't turn on

With Everything except the white ribbons unplugged I get a 7 blink code.

sounds like you don't need the remote and was locked so I'd get a meter and resistance check across sn2 and ss11 for short cct. if you took those 3 white ribbons off it most likely would have turned on with no error code. avoid reconnecting those leads after a power cycle especially p35 for 5mins or so or check there is no residual voltage.

Re: Panasonic tc-p50x3 won't turn on

After plugging everything back in it does the same ole stuck in standby. As far as checking the sn and ss boards how would I go about doing that. And what should the resistance be?

Re: Panasonic tc-p50x3 won't turn on

at this stage you want to find what is shorted. so you need a multimeter to measure resistance which I expect will be a short or 0 ohms , something low but you'll know because it will be low.

At the S2n connector for example?

Sn2*

Re: Panasonic tc-p50x3 won't turn on

star there with the lead removed and measure across the 2 pins on the sn board sn2. you should also check the ss across ss11 just in case also isolating the cable and I would download the manual as that will give you pinouts

Ok that's tomorrow's project. I'll check back tomorrow with some updates hopefully some positive news

I also have a tc-p50x5 with a cracked screen. Wii remote got it. Will any parts interchange between the x3 and x5?

Doubt it unless someone here has experimented fitting them. usually cracked screens short out the boards anyway if they're on when they get hit so the SN or SC from the X5 maybe toast.

Remote woud work LOL.

Should be here tomorrow. I'm pretty impatient haha

Re: Panasonic tc-p50x3 won't turn on

Kind of off topic but I have a vizio that's giving me problems. It's a e321vl and it works perfectly until you go to shit it off and turn it back on shortly after. One time it shut itself off and wouldn't turn backing also

So I got the remote today and it has the same result as pushing the power button on the TV set. It can turn the standby light off and turn it on. Still makes the same relay click sounds but still no screen prime or anything. Is it possible the screen went and just won't turn on?!? About out of moves here haha

On the SC board, locate transistor Q661.
--Its on bottom heatsink.

Check to see if its short.--If so, there'll be a whole load more short on that board.....

How so? Most likely you have a shorted SN board but without getting a multimeter and checking for shorted Vsus lines on the SN and SS boards you're not going to progress.

Or , just purchase a SN and SS, replace both and it'll probably start working again
