TV going yellow

[Mahaon]

All of the sudden, my 60" Hitatchi LCD is getting a yellow tint to the picture. First the whites stopped looking white, now it almost has a yellow tone overall.

Any idea what might cause this? DCR, other experts?

maybe it's a lemon:teehee:

is there a reset or an auto config button anywhere?
