8 blink error code on my panasonic plasma

8 blink error code on my panasonic plasma

I have a tv that we are trying so hard to fix. We refuse to let it go unless we really have to. We have a panasonic tc-p65st30 and from one day to another the tv has a 8blink error. We have replaced the SS board and the Main board.( I think thats what they are called). Even replacing both boards we still keep getting the 8 blink error code. Can anyone help us please? We would really greatly appreciate it.
