Panasonic TH-50PZ80U 7 Blinks

Re: Panasonic TH-50PZ80U 7 Blinks

if the buffers have been isolated and the tv powers up normal and the green led is on I would say that's a SC pass and so the buffers or panel would be causing SOS7.

Re: Panasonic TH-50PZ80U 7 Blinks

So, I isolated the boards, I Disconnected SD board from SC board and SU board (2 connectors SD-SC, Ribbon Cable SD-SU) and ran a jumper from L801 to the VF_Ground screw on the SD board, still 7 blinks. I did the same for the SU Board, (1 connector SU-SC, Ribbon Cable SD-SU) and ran the jumper to the ground screw on SU board. Still got 7 blinks, does this mean it has to be the SC board, even though the green light on SC is lit??? I also unplugged all the ribbon cables (at a seperate time) from the SD and SU board collectively to make sure that the Panel wasnt bad (I read that isolates the panel), with all the ribbon cables unhooked i also got 7 blinks, which means the panel should be fine i believe

so both buffers or panel is bad for me. no errors with SC on it's own and a replacement Sc did not fix it.

The only way to make it stop the 7 red blinks and stay on is to unplug the sc board though...so doesnt that mean it is bad?

Ok, i've misunderstood post 40, thought you were saying that after you jumpered the SC it powered on and the SC led was on.

My bad. In that case if the Sc was jumpered and SOS7 then you'd presume bad SC.

I have not tried this out myself but I have on the newer models which have a SC50 2 pin jumper for this exact same test and the Sc will power up normally if good with the buffers disconnected.

you might want to check out the resistances at the buffer board connectors too just in case they took the Sc out.

Not sure if there's a document for that as a guide.
