Optoma MovieTime: The Lamp that Won't stay on

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?

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.

Why won't my Optoma DV10 projector won't turn on?

On an Optoma DV10 if its not the lamp timer, then it might be a cooling fan that needs replacing. Take out the old one, and look-up its part number online. If you don't feel confident taking it apart, have a qualified person do this.
