Re: Panasonic TC-P42X2

The low 165V also seems really suspicious to me. Maybe the TV was hit by a surge.

Re: Panasonic TC-P42X2

I checked v at all the optos all have 5v on the secondary side but ! has 11v
I will take good pics of the PS

Had to use flash, But everything is visible, Let me know if you want to see the foil side.

Optical closest to the center was 10v on the upper right leg.

Re: Panasonic TC-P42X2

So, if you CAREFULLY tweak the Vsus adjust pot, does Vsus change?

I had a plasma TV which would display a faint image down to 130V on the Vsus, so I think sometimes else is up, but there is the possibility if it is designed for a high ~210V it might not show anything on 165V. Here's where you may need to use that scope .

Re: Panasonic TC-P42X2

see that is the thing, the PS treats the SN as a dead short when it is not. with SN plugged in and for the brief moment that the vsus powers up I measure about 1v then the psu shuts down the vsus relay.

Re: Panasonic TC-P42X2

Ah, that's where it gets tricky, because this set doesn't have removable buffers. But you can still tweak Vsus with them disconnected.

Re: Panasonic TC-P42X2

Wish I had the means to load test this ps first, and vsus info on the panel would be great too

Re: Panasonic TC-P42X2

A 120V, 100W light bulb would be a good load. It might not last very long on 165V, but it could do a temporary job. Are those illegal in Canada yet?

Re: Panasonic TC-P42X2

lol nope not outlawed yet, But I suspect soon. I will try it, not sure if I have jumpers I would trust at that power though.

Re: Panasonic TC-P42X2

Solder to the light bulb and insert wires into one of the connector ends, the end which would normally plug into the SN. Tape all the wires up so you can't easily electrocute yourself.

Measure the cold resistance of the bulb first; it needs to be at least ~165 ohms to ensure it doesn't load it down too much.

The set will still shut down without working SN or SS due to 6/7/8 blinks error but it will run usually for about 1.5-2 seconds.

Just added a TCP42S2 to my collection.

Re: Panasonic TC-P42X2

Man you are lucky if you can't get the X2 working you should be able to get the S2 working right? Was it free? I only once got a crappy 42 inch LCD for free. Everything else I paid for.

[IamCanadian]

Re: Panasonic TC-P42X2

yup free! Hope to get one of them working.

[tom66]

Re: Panasonic TC-P42X2

I'm sure you can get both working, open a new thread on the S2 when you're ready, I'll try and find a manual for you.

[IamCanadian]

Re: Panasonic TC-P42X2

I have the training manual for it. but I will for sure.

[tom66]

Re: Panasonic TC-P42X2

Do you need the service manual? I'll find and upload that tomorrow when I get a chance. Late now...

SM would be good, no rush Thanks again for all your help!
