A few months ago, the lamp 'popped' and the projector shut down. I assumed the lamp was gone, but it came back on (after sitting for a while). When I noticed how hot one side of the projector was, I thought maybe a fan had burned out. So we set up a little fan to blow air across the unit, which solved the problem for a number of months. This summer, the external fan solution has failed, and the machine again shuts itself down (without warning), but now it turns off after only a few minutes of play time. The lamp currently has 507 hours. I have adjusted various settings to reduce the brightness of the lamp, to no avail. Is this how lamps fail? Is it a temperature sensor? And/or the cooling fan? Are their repair options other than sending it to Optoma?

Re: Optoma MovieTime: The Lamp that Won't stay on
Its definitly a cooling issue.the temp sensor is working because it shuts the unit down.when a lamp goes it goes just like a light bulb.you can open up the unit and locate the fan take it out and go to a radio shack a match it up to a universal fan.

This is listed in Projection TVs but I am assuming this is for a projector by your statement. This is a common thing to happen when the lamp needs to be replaced. After you replace the lamp you will have to reset the hour counter back to zero in the settings menu.
Secure the lamp cover and the air filter cover of the
projector body if the projector does not power on. Ensure that the power
cable is firmly connected to the projector and an active power plug. If
the projector was turned off and then on quickly--let it sit for 90
seconds before trying to turn it on.
Replace the projection lamp if the projector will not power
on or if the lamp indicator is flashing. Turn off the projector and let
it sit for at least 30 minutes. Locate the lamp cover and remove or
loosen the lamp cover with a screwdriver. Carefully remove the
projection lamp from the projector housing using the handle, if
Place the new projection lamp into the projector housing and
secure it to the projector. Replace the lamp cover and reset the lamp
timer. Power on the projector to ensure the new lamp is working
Remove the projector from the enclosed area to allow air
circulation if it constantly overheats. Place the projector into an open
area and make sure there is no blockage for the ventilation holes.
Unplug the projector for at least 45 minutes to allow it to soft reset.
Clean the air filter to allow the projector better air
circulation. Turn off the projector and unplug it from the outlet.
Remove the air filter cover and use a vacuum to remove dust from the
area. If the filter is unable to be cleaned correctly or is damaged,
then replace it. Pull the air filter from the projector and place the
new one in the now empty slot. Close and secure the air filter cover.

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.

carefully take the lamp cover off, and see if there is any glass pieces inside. if all looks Ok, then unscrew the lamp housing and remove the lamp. check for any damage. be careful not to damage the lamp or bump it. These lamps generally contain mercury vapour, so try not to inhale anything if it's broken.
