Why Does The Lamp Fail To Light?
I have a NEC vt480 projector. I started having this problem a few years ago occasionally but now it fails to light. The red light flashes 6 times. I have tried several times and the projector will start the process and just as it starts to shut down the bulb will flash on but only for a moment. The fans come on and run and sound normal.
