My bulb was replaced Friday on my projector. Today, I start it up and it runs for about 15 minutes then the system shuts down. I can turn it off for 5 seconds and restart it. The projector will come on again, and then if will last for about 15 minutes. The bulb will go out and the projector will shut down. Any suggestions?

SOURCE: unit powers up, fan shuts down no light.

The unit could be able to sense fan operation and prevent the lamp from lighting since this could cause heat damage or even a fire if allowed to light without any cooling.
If you can see the fan, try pushing gently on the blades, left, then right, to see if the fan shaft wobbles.

i believe your problem is heat the bulb is getting hot and the air or fan is not working properly so when it hits temp it automatically shuts off check your fan air flow filters etc

reset the lamp and filter timers. turn the projector off then back on.

try looking for your thermistor usually located near the wind path its a small block the size of two match heads usually mounted off the main board with two wires this is your 'heat switch' so to say, also check your fans are clean and running there is normally more than one.
