My LCD tv model LN46A650A1FXZA picture turns green after about being on for 5 minutes. Then is gets fuzzy and green


I have the same issue. TV is ~ 2 yrs old. Ruled-out cable-box & HDMI cables (green present in menu mode with no cables attached).

Screen turns mostly green, with a crappy picture. After a few days, a normal picture just appeared. Today I powered-on, the green screen stuff came up, then a minute later a good picture for about 20 minutes, back to green-stuff for 10 seconds, then good picture.
