i had this same problem with my dlp. there could be a number of problems so i will tell you how i fixed mine. i had my dlp for 4yrs before it actually started to turn of by itself every 30-60mins like clockwork while the standby and lamp led's were flashing at the same time. luckily my dlp was still in warranty under best buy at the time. but the only thing they did was replace the bulb. of course they sent in an incompetant service man but that's a different story. so now the bulb was replaced, tv was now working fine. that is until we had to move, which means we had to travel with this tv on a truck and move it in to the house. then this problem started occuring again, shutting off with standby and lamp led flashing. i thought "this can't be happening, the bulb was replaced only 3 months ago". i knew it wasn't the bulb because it was new. so i came to this web site for help. i read the troubleshooting guide available on this website. from what i gathered in this vague guide, the door to the bulb was loose. also available on this site is a how to video on how to replace your bulb, which will be helpful if this is your first time doing this. so i opened the door to the bulb, with power unplugged of course, and found out that the screw used to hold the bulb in place was not on tight, which was replaced by the best buy service man and of course did not do a good job. so i tightened the screw, cleaned up the dust, screwed on the door and the problem hasn't occured in a whole week. i hope this was helpful.
