I have a 3 1/2 year old Sony 50" Grand Wega rear projection TV. The TV powers up for about 3 seconds, then will have a picture and sound 2 or 3 times for about 3 seconds each and then go black. After about 5 minutes the screen goes completely dark and the red light blinks 3 times for about 2 minutes and then it shuts down. I have removed the bulb and the bulb cover piece. I did not replace the bulb yet because it does not look blown, and because the screen actually comes on in full color once or twice, as well as the sound. I have tried to use the cable box, DVD player, and a memory card, yet I get the same result. Any suggestions?
