Re: 55 inch Plasma Viera (VIERA TC-P55GT30) not turning on. 7 blinking red lights.
I am sending the SC board to ModusLink, it will be a repair and return as they don't have the boards in stock. When I get the SC board back, shouldn't I be able to connect the ribbon, and power connector. Leave the SD/SU disconnected, and not grounded and jump SC50 again? If the 7 blinks do not happen, then the assumption is it was the SC correct?
Is there anyway type of troubleshooting I can perform to isolate if the issue is with the SD/SU board?
If...

Re: 55 inch Plasma Viera (VIERA TC-P55GT30) not turning on. 7 blinking red lights.
I didn't have a jumper, or alligator clips small enough, so I used some speaker wire, split the two sides, and stuck them in the socket for SC50 over the two pins. The buffer connectors between the SC, and SD/SU board were disconnected, and so were the ground screws for the SD/SU board. The SC board was completely screwed down. The light still blinks 7 times, so that is the SC board correct?

Re: 55 inch Plasma Viera (VIERA TC-P55GT30) not turning on. 7 blinking red lights.
Ok So disconnect SU/SD boards from SC board.
Take out 4 bigger screws on SU/SD boards
Alligator clip, or something that will go across the two Pins of sc50
If no Blinks it's the SU/Sd boards. If it still blinks then it's the SC board.
I'll be doing this today. Thanks....

Re: 55 inch Plasma Viera (VIERA TC-P55GT30) not turning on. 7 blinking red lights.
I had all 3 unscrewed. So I need to have the Sc board completely screwed down?
As far as the SU/SD are the bolts that ground those boards the bigger of the srews? I believe there are 4 bigger one's that go along the front, and then 3 smaller one's that are at each end, and in the middle.
Where can I get a 2 pin jumper? Or can I just hold a piece of wire across the two to short them together? What outcome's are possible and what do they tell me?...

Re: 55 inch Plasma Viera (VIERA TC-P55GT30) not turning on. 7 blinking red lights.
Ok disregard my last message. I lifted up on the SC board and then realized that the connector with the tabs came out, not the pins separated. That was my first thought earlier, that's what it seemed like, but I got no movement out of the connectors.
Here is where I am at. I disconnected the SU, and SD board from the SC board. I still received the 7 blinks. Then I disconnected SC20, and Sc2 (the ribbon and power connector from the SC board), and now I'm receiving 8 blinks instead of...Last edited by Havasu; 01-03-2015, 08:44 PM.

Re: 55 inch Plasma Viera (VIERA TC-P55GT30) not turning on. 7 blinking red lights.
I'm just not getting it yet. In what direction do these fingers come out? Do they go straight back? Does the SU/SD board go up while SC board stay in place?
I am depressing the tabs, and pulling back from the SC board side? What am I missing. It really looks like those metal fingers go all the way through from The sc board through the connectors all the way back to almost the tabs, and I just don't see how they come out....

Great. Thanks. I really appreciate it. I may have some more questions along the way here. I just want to see if I can narrow down which board it is. I'm following a flow chart posted much earlier in this thread....

The connectors that have small flexible metal fingers on one side that are into a connector with the spring tabs you were talking about. I pushed in the tabs, and started to pull, but they felt like they were hung up. I didn't want to damage them, so you're saying press the tabs and pull firmly? It just seemed with the other two still connected I might damage the others pulling back too far....

Also, I can't find the Panasonic parts store that people have referred to. I have searched for it, and just can't find it. I have been having trouble just finding the SC and SU/SD board parts. I really just want to order them all and return what I don't use, to speed up the process.

Re: 55 inch Plasma Viera (VIERA TC-P55GT30) not turning on. 7 blinking red lights.
I'm having a moment where I feel really dumb. I have a TC-P55GT30 and yes I have the 7 blinking lights of death. I've researching and reading this thread. I'm in the middle of trying to follow a flow chart that was posted on how to tell if the issue is the SC board are the SU/SD board.
In the first step I'm supposed to disconnect the SU/SD board from the SC board, leave the SC board connected and see what happens with the lights. All connectors are easy to disconnect except for the...
