DLP Twon't turn on, blinking green lamp light then shuts dow

by Newfieace - 6/16/10 6:21 PM

50" DLP TV. When I turn on the TV I hear the chime as if the TV is going to turn on. I get the flashing green "Lamp" indicator on the power button on the TV which is normal. However the TV never comes on. No picture or sound. It just sits there flashing the green "Lamp" indicator for about 1.5 minutes. While this is happening I hear the fan running as normal and I can see that the Lamp is on by looking at the back of the TV. After about 1.5 minutes the lamp indicator stops flashing and then there are no indicators at all. After about another minute I hear the fan stop running, the LAMP goes off, I can see this by looking at the back of the TV, and the Red Standby light turns on. Basically the TV shuts down.

Can anybody give me any ideas on what to look for as I troubleshoot or what you think may be the issue. Here are my thoughts:

Doesn't look look the Lamp is the problem since it comes on ok as seen from the back of the TV.
Could it be the color wheel, not sure why this would cause no sound and if the TV detected a bad color wheel it should have indicated that with flashing lights as indicated in the manual.
Could it be part of the safety circuit?

I'd really appreciate any advice or tips anyone could give me.
