Re: sony rear projection tv keeps shuttin off
If you have correctly seated the lamp door, then check the door itslf near the screw that tightens it down. There is a little tip that sticks through a hole to engage a safety switch. Either the tip has broken off or the safety switch has gotten damaged.
