SOURCE: I have had a panasonic
This is an old posting, but will reply anyways.
I am not sure if this is the same problem that I had , but sounds similar.
I found that there were power surges, or lack of power. I could see my power bar blinking at the time this happened.
So after trying everything under the sun, I plugged it into another outlet with the power bar, and have never had a problem since. It seemed that for some reason I had surges in that line, and have no idea why.
Not sure if this is what is happening to you, but maybe might be of some help to someone else.

If this is a DLP (digital light projection) ? If so, the lamp is probably out. DLP's are infamous for lamp failures. You can replace that yourself if you can find someone to order it from. Look it up online or check with a local repair shop. The only thing to be careful with is when you self diagnose a TV and maybe something else in the TV is causing the lamp to go out, you may find a new bulb goes out shortly after you put it in. So... it's best to have a certified technician diagnose the TV to make sure it's not "just" the bulb.
Hope this helps!
