So we have a 50" Panasonic that made a move about 1200 miles across the country. When we went to hook it up at the new place, it just starts flickering and has a black bar in the center horizontally. However the menu is overlaying it. Some googling showed it might be the C board cable or cboard but then more googling shows that if the menu overlays it then apparently not.

Any suggestions on what I might try? I'm not afraid to break this TV open as my primary job is in depth computer hardware repair. I couldn't find much on horizontal bars other than the "Why are there horizontal bars around my movie" lol.





EDIT:

So on TV it flickers that black bar. All other inputs are just grey or black but I can't get anything to input.












When plugging up something into component I get a solid green screen, that's it.

Probably something knocked loose or unseated in the shipping process. Tom669 a forum poster may be helpful here.

SOLVED:

The logic board, or the board that piggy backs onto the main board (board with video components built in) must have had a bad connection. Unplugged it, plugged it back in.
