My projector is just out of warrenty and has not been used much. After several months of not using my projector I tried to hook it up to my tv and the green light came on then a few seconds later a solid red light appeared for the lamp and temp display. The lamp will not come on. I used an air canister to blow out the dust with no success. I do not hear the fan running and not even sure if it is supposed to without the lamp on. Can someone please give me some tips that I could use to repair my unit?
