Dell 1209S Projector, tries to turn on, and the fan comes on for 30 seconds and then goes off again. It tries this several times and then the light bulb icon comes off and it doesn't do antything else


Lamp is burned out or makes a popping sound.
When the lamp reaches its end of life, it may burn out and may make a loud popping sound.
If this occurs, the projector does not turn back on. To replace the lamp, see on page 38.
LAMP light is solid amber If the LAMP light is solid amber, replace the lamp.
LAMP light is blinking amber If the LAMP light and the Power light are blinking amber, the lamp driver has failed and the projector will automatically shut down.
If the LAMP light is blinking amber and Power light is solid blue, the color wheel has
failed and the projector will automatically shut down.
Unplug the power cord after 3minutes then turn the display on again. If this problem
persists, contact Dell™.
TEMP light is solid amber The projector has overheated. The display automatically shuts down. Turn the display on again after the projector cools down. If the problem persists, contact Dell™.

Projector screen turns off after 10-20 seconds


Is the projector receiving a source signal? if not it will power itself down after whatever time you have it set to do so when no signal is present.
Just an idea?

Light flashing red, projector will not come on. Turned off and when turned back on the light is green and then flashes red a few seconds later.


do you hear a high-pitched whir when you turn it on? if not, you have a bad colorwheel that needs replacing. the lamp won't turn on if the colorwheel is not spinning. also check the fans. you can get the part from an infocus service center or send it in to them for repair. either way, try av solutions in ny. they're really good. www.avsolutionsny.com

Sanyo Pro xtra projector - warning light


We have a similar situation with our Sanyo Pro Xtrax. It will be on for about a hour and then the "warning temp" light would come flashing red, and the project would turn off on its own.

When u switch it on a timer comes on for 30 seconds then the projector turns off can any one help please


Had the exact same problem, after my projector was powered off upruptly.
Turnedout all I had to do was push down slightly on the tempreturesensor/fuse (is opens the power circut if the projector gets too hot,and thus doesnt allow any current)
Here is the full repair/service schematic for the projector. It should help you locate the sensor.
Good luck
