Panasonic TX-50CX680B picture upside down after replacing main board
Our Panasonic TV (TX-50CX680B) wouldn't power on (after a lightning strike took out our phone line, router and TV via the ethernet cable) I diagnosed that the main board had blown so got one online and replaced it (TNPH1120 2A). TV now powers up and functions fine other than the fact the picture is upside down (rotated 180 degrees... i.e you can still read the menus etc if you were doing a hand stand!).
I tried accessing the service menu and discovered that pressing vol- on the TV and pressing red 3 times brought up "CS Maintenance Menu" but nothing there looks helpful. Is there a different button combination for accessing the actual service menu? Saw online some TV's have an "invert image" setting in the hidden service menu.
Any advice is appreciated.
