Panasonic TC-P65VT30: Set 7 blinks times, replaced boards, still dead

Looking for some help. I have a Panasonic TC-P65VT30 plasma set. Went dark 9 months ago: seven blinks of death.

Did my research: replaced SU, SC and SD boards.

Still does not turn on. Still dead. Still 7 blinks of death.

Pretty sure I have everything hooked up correctly.

Any ideas? I have an SS board, I could replace. But what I’ve seen indicates the SU, SD or SC boards.

Thank you in advance.

@maharry the 7 blink code is a common issue with is with one, both, or all of SC board, SD board, and SU board. The most common failure is the SC board. Check for arcing evidence on the mounting screws for the SD board. You also want to post lots of images of your boards and their location with your question. That way we can see what you see Adding images to an existing question

As you see it is the SC board that reports it but can be the Vsus board as well. You can do some basic checks with a multimeter but we’ll need to see your boards to point it out.

Dear old,

Thank you very much for your reply. I’m very interested in learning more, in supporting the Fix It movement, and in getting my tv going!

I’ve uploaded photos of the tv back, and closeups of all boards.

Thank you in advance. Please let me know if you need any further photos. I do have a multimeter, so there’s that. Thank you!!!!!!
