Re: Lamp

Red light indicates lamp is expired. even though you get temporary light, the lamp is shot. Try BULBMAN.COM for a new lamp.

In the manual there is a chart which will indicate the nature of the failure depending on the number of times the red led flashes before a pause.

Most common is the projector's lamp timer has exceeded the operational lamp time limit.

While the projector's red led is flashing, press the volume up and down buttons on the projector simultaneously and hold them both in for 10 seconds.
This will reset the lamp inhibit protocol.

However if the lamp has thousands of hours of use you need to replace it before it actually fails.

No light come on from the projector

Thats the projector telling you that you need to replace the lamp. Lamps usually lasts for about 2000 hours so if you had it for a while you may need to replace it. and enter your make and model or go to and find a few retailers in the US that sells lamps.

good luck

Won't turn on, only flashes red light

Probably the filter is blocked. Unplug the power lead at the back and leave for about 30 seconds. Plug back in and it should work. The first opportunity you get, buy some compressed air and give it a good clean.
