I've had this same problem ongoing for a couple weeks. Finally, tonight it would shut off every 20-30 seconds, stay off for another 20-30 seconds then come back on. It turned out to be my bulb. I blew the TV out with compressed air, removed the bulb and disassembled it. Taking the bulb out of the plastic cage I then remove one of the metal screens at the top of the bulb, it just has little clips holding it in. I took a bottle of rubbing alcohol, some Q-tips and proceeded to clean the inside of the bulb through the screen hole. After cleaning the inside I put the screen back in, cleaned the outside of the bulb with a rag and alcohol, then reassembled everything. The TV is much brighter, I had to turn down the brightness setting and has been running the last few hours without an issue. You can avoid all this by buying a new bulb but I don't have the money right now to replace it and I'm cheap so I'll milk this bulb for everything it has. Heat kills bulbs so if you clean the screens and blow out the TV once every couple months you'll get a lot of life out of it..... I'm almost to 4 years on my original bulb and my TV is on constantly!! Good luck to all!!

You need a lamp. This is a common symptom. I hope this helps. I have a tutorial on the function and failure of lamps, check it out if you like. It explains why your TV is doing this. I hope this was helpful.
