Test for a short on the SC across where the brown and white wires would go, with the connector unplugged from the SC.

Note buffers may get power thru those screws, seen it a few times!

thanks tom will get pawnshop to bring it back over an give it a test! with the loop enabled an all other boards disconnected it still flashed error! been reading service manual on it! of course they say it not repairable!

Re: panasonic TC-P50S30 50 inch

Surprising for Panasonic to say that, but I have heard of the plasma panel going short circuit between lines. Unplug buffers to confirm.

Re: panasonic TC-P50S30 50 inch

everything runs through main board! if you disconnect it! nothing works.

Re: panasonic TC-P50S30 50 inch

Re: panasonic TC-P50S30 50 inch

they ordered an installed an sc board an still same flashes! except this time when i isolate it from the su/sd boards i don't get blinking led! so last sc board was bad! so any way to test an isolate what is wrong on the sd/su boards or easier to just replace?

an they was no short at that point tom, will ask for old board so i can test it too!

Re: panasonic TC-P50S30 50 inch

You can run it with one SU or SD, then jump SC50, for half a picture.

First post!

Got the same TV and found the SC board was shorted. I replaced and TV powers up but picture is funky. I'm sure I'm not the first, so should be easy for you guys to point me to what now needs replacing. I have attached a picture. Basically pinkish blue on both sides with a dark ghost image in the middle. Thanks in advance.

have you found the problem finally? I have the same issue after replacing the upper buffer board. Initial problem was the 7 blink
