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.

There are two possibilities, the T-CON board or the main board itself. You can try using cold spray for electronics troubleshooting on the T-CON board to see if the problem goes away, T-CON board is mounted under a metal shield.

I have a 2 year old LG LCD TV (model 42LG60) and I am having problems with the screen. I turn it on and everything is fine for a few minutes and then the screen goes to red or green lines that are fuzzy....


Not really a solution, sorry, but I've got the very same problem. I haven't noticed the time before tv faults, but nontheless, it greenscreens or like in your case, redscreens as well. I've been told to open the back, which I did to check the status of the capicitors, which I've done. But, the capacitors "seem" fine. No bulging or popped tops. So, I'm at a stand still...not sure what to do at this point. If someone gives you solution, I sure would appreciate your forwarding it on to me. Thanks. Robert
