I have a blue hue over my entire screen (was green until I messed with it in the service menu). Yellows look flourescent, dark skin looks bluish and light skin looks colorless. Something similar happened shortly after I got the tv in 2003. A service tech came and fixed it. It happened once again and I found "service tech only" instructions online somewhere that helped me fix the problem in the service menu.
Unfortunately, I lost those instructions. Now, 5 years later, I am experiencing the problem again... I bought a service manual which was not helpful. Can anyone point me in the direction of the detailed instructions to fix this problem?
