The menus are definitely there and switching though, as I can hear when I change inputs. So does this point to a main board issue? Logic board? Panel? Anything else?

Hey all, my name is Peter. I have a plasma TV I'm trying to resurrect and have been unable to find anyone with a similar issue. Just found this board though and it sounds looks like the most technically savvy group out there.
