Charlie, 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. It was such a big issue that Panasonic even offered a warranty extension because of this. Not sure if that would still apply to your TV, I'd call them at 877-95-VIERA and see if that still works for you. Otherwise you will have to replace the boards. 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. This way we are having a common reference for further issues.
