Television and Home Theater

I have a Samsung HCN4727W that is in our basement and has not been used very much. Last week we started having problems turning the TV on, it would power on have no picture then shut off. I was able to get the TV to stay on by pushing the TV/Video button a couple of times(it seemed)? We also noticed after the picture would stay on it was raised up about 3 inches. Now tonight after getting it to stay on it appeared to be a green and red double visoin picture and the picture was still raised up but seemed bowed at the bottom.

Trying to help friend with this TV. I've done my part by buying new bulb but alas that not help.

TV: Mitsubishi WD-62528

Turn TV on and the  Lamp indicator light blinks green for a minute. Status light blinks yellow continuously.

Replaced the bulb, cleaned the air filter. No go.

Suggestions?
