You can try that, limit temperature to about 90C.

It seems like heating up C7011 causes it to work. I am using a small nozzle just aiming at that cap.

Re: Panasonic TC-32LX85 Dead

thats the cap you have changed a couple of times? i wonder if the track has a break in the circuit? as you already have replaced that cap unless its something else really close to that capacitor?

Re: Panasonic TC-32LX85 Dead

Im waiting for it to cool down again then try to heat it from the side to make sure, but I suppose it can be anything close that is heating up too.

Re: Panasonic TC-32LX85 Dead

can you post a picture of the area? are there parts on both sides of the board in that area?

Re: Panasonic TC-32LX85 Dead

Pics... C7011 is directly right of transformer.

Re: Panasonic TC-32LX85 Dead

Im trying to use freeze spray and heat to isolate the area, but I can't seem to get it stay 'off' with the freeze, but the heat definitely works to get it on. I think it's something on the bottom.

The last time I got it stay off I blew heat down the 2 small holes from the top, which are right above Q7000 and it came on instantly. Ill have to keep experimenting..

Re: Panasonic TC-32LX85 Dead

I think this is fixed, replaced IC7000, Q7000, and PC7000 and it seems to be working consistently. I suspected Q7000 but I replaced all 3 at the same time just to be sure.

Thanks for posting the follow-up, hopefully it will stay working.

Re: Panasonic TC-32LX85 Dead

As of now still working after several cold starts. So thank you Bud and Tom for the help. FYI the VCC at IC7000 is about 15.2V now as opposed to around 14.5V before which still seems low but it's working.

Re: Panasonic TC-32LX85 Dead

Hello, new here, i was looking on the web info on the same tv .
Mine does power on and shut off after a few minutes, then it blinks every 4 seconds not 3 as in the Inverter SOS.
I see no swollen caps i re heat the 3 items kevinm34232 said.
and this time flickered a bit.
And left it alone.
I will appreciate any help.
