I have an older mitsubishi rear projection tv, about a 50 inch. I can turn it on in the morning and the green light comes on and after about 10 minutes it will make like a double clicking noise and the green light will go off. I can beat on the side of the tv and it will come back on and usually stay on until the next day. Anyone got any suggestions? I hate to take it somewhere because of the cost, i could probably go get another one for what somebody would charge me.
