Hi the first time i turned the projector on it shot optoma onto the wall and started searching for a source but i had none hooked up to it so nothin was displayed but suddenly the image shut off and the projector was still on. I tried to unplug the system and repower it back up. The lamp will turn on for about 5 seconds but no image ever appears even while the lamp is on for 5 seconds, but the little bit of light it produces will turn off in 5 seconds and the fan and power light is still on. What the heck is wrong with this thing? thanks!!
