SOURCE: Toshiba Projector won't turn on!!!

I had the same. Try to press the "input" and "menue" buttons and plug in the power cable. No control light should be active after that. Press the "power" button and it should work.

SOURCE: Reset Lamp Hours Timer

This works on a couple different Toshiba models -- might work on yours...

Make sure the main power switch is OFF. Hold the "ON", "MENU", and "INPUT" buttons at the same time and turn the main power switch on. Keep them held until the yellow power standby light comes on, then let go. It is done.

Why is the light strobing ?


Lamps will sometimes flicker when they are near the end of their life. Look through the menus and check the lamp hours, if it is over 1000 hours I would try another lamp. This could also be caused by the lamp ballast, which is the power supply for the lamp. If the ballast is bad, repairs will cost almost as much as a new projector.

I've had the same problem with my projector three times (usually whenever there's a sports championship). You just need to call optoma, get an RMA number, and ship it to them. Theoretically they'll fix it under warranty and send it back free.
