Question about Panasonic PT-40LC12 40" Rear Projection HDTV
In response to your question about my set, picture lasts for 30 sec and goes off. The red light blinks 4 times stops and then repeats. Thermistor checks out and the bulb appears to be good for at least 30 sec. All fans are turning. Please be specific. Thanks Ken
Problem is the bulb.
I had this exact same problem. Even though the bulb appears to be good, it is drawing too much current to run properly, and the ballast is shutting it down.

My set had the exact same problem. Read mikeygstl and changed the bulb and sure enough the set works perfectly again. Even though the old bulb did come on, it had a 'foggy' appearance in the lens once I took it out - so something was wrong with it.

It is one of three things...the bulb, the ballist, or the fan filter is clogged.
