Question about Panasonic PT-50LC13 50" Rear Projection HDTV

1 Answer

Have sound, no picture

Bought this TV about 4 years ago and am on the 4th bulb, which was recently replaced. Last night while trying to view a Comcast "On Demand" show, it went blank. This has happened a few times before, but I have always been able to get it working again (but not sure how). I have hit every button on the remote with no luck. I don't think the lamp is bad, as I can hear the sound, and see glimpses of a picure when hitting some buttons. Any suggestions?

After fooling around with all of the buttons, and disconnecting the power to the TV, it occured to me that it may be the Comcast digital cable box. I unplugged the cable box for a few minutes, plugged it back in and the TV works just fine!

Bulbs keep blowing


You may be touching the bulb (ampule) and leaving a fingerprint on it which creats a hot spot and blows the bulbs up prematurely.

If you have not changed the lamp in the 4 years you have had the tv you will need one soon if not now. is sound from tv or receiver, when the lamp dies usually no sound from tv. If you have sound from the tv try unpluging power from wall to reset and try again
