I turn my tv on the picture and sound all work and after about 20min the picture goes to a black screen and I still have my sound. I turned the tv off wait about 5 min turn it back on the picture come on then turns to a black screen again. The longest it stays on is when I first turn it on, after that it only last about less than a min.

If you have electronics experience - check the power supply and make sure you are getting the correct voltage to your inverter boards and main av board - also do you see any movement on the screen take a flashlight and shine on the screen - if you can see a dark image on the screen check inverter boards and power first.

My tv is doing the same thing, on about 30mins then goes black. I still have sound. I turn it off then immediately turn back on and lasts about 5 mins. Have you ever found out what the fix is?

I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
