The screen on my 60 inch projection Zenith tv is slighlty blue on the sides. When I turn the tv on it suggests replacing the lamp, although I am not sure that this is related to the blue screen.

You need to replace the convergence IC's

I would check with LG/Zenith on this, there was a update sent out to add a collection cup in case this would happen. If leaked on the board it would be to costly on repair with the board is still available.

there is a posibility that there is a magnet near... see if there are big speakers around others that aren't the one that has built in..

the other posibility is that it has loss configuration... try to check the manual for proper configuration or send it to a authorized sony repair guy so he might flash firmware.

hope that helped

i just bought one of these with the same problem and had a repair man come over. said it has a h.v. power supply problem even though the red light is on and some little board cant read the handwrighting on estimate but will follow up. must replace the whole board the power supply sits on, it is the big board that the power cord connects to in the back of the tv... other board it is located behind the little panel in between the speekers on the front it is the little one in the left hand top corner. parts/labor mainly parts +/-$500. is it worth it? ihave not seen this tv working so if there are any comments about the picture quality i woul like to hear/read them. hope this helps.

I just found the solution on another model of Zenith TV. Hold the enter button down on the TV and the MUTE button on the remote. In approx. 5-7 seconds a screen will pop up asking if you want to reset the lamp timer. Hit the bullseye button in the middle of the arrows and it will reset. Worked perfectly.
