Samsung HL-R5067W DLP Picture Won't Turn On

Hi all. My DLP has decided today to not start. When I click the power button, the green 'timer' light on the TV flashes for a few seconds then the 'lamp' light starts flashing. Does that for about a minute and a half. During this, the lamp does turn on and the screen gets that soft glow from the light. After about 2 minutes, I hear a click, the lamp turns off and the green indicators on my TV shut off. I do hear a faint fan like sound from the TV. Can't tell if it's the color wheel or maybe a fan. But it's very quiet. Color wheel is less than 8 months old and the lamp about a year old. Anyone have any ideas? Thanks.
