Won't turn on the TV

I have Mitsubishi 65" Diamond series rear projector HD TV with model # MS65711, It won't turn on the TV, I checked the power supply and remote control and they are working, I did reset the system on which the green light will blink for 1 minute and when the green light went off the TV should be should be on, but it won't. I spoke a cable installer and he said the lamp/bulb was busted. So, I took his advice, but I have been looking for many months their is no bulb/lamb that I could find until accidentally I went into your site tonight. I read some of the articles and they are very interesting. I need help on my TV. Is their anyone who can resolve my problem? My email is   [email protected]
