It sounds like you have an overheating issue, Look through the vent slots and see if you can see a build up of dust. If you can then you will need to open the projector to clean it properly. You could try blowing it out with a compressor but be sure to use one with a water trap to stop moisture getting into the projector. You can buy cans of compressed air from electronics stores if a compressor is not available. Some models of toshiba also have issues with the temperature sensors, They are attached to the metal heatsink and the plugs that attach them to the circuit board can loosen which makes the projector think it has overheated. Hope this helps
canned air from the outside is good, but a lot of the dust collects on surfaces and bakes on. for best results, remove the top cover and blothe dust out of every nook and cranny, wipe it off of the fan blades, and make sure all of the fans spin well. you may need to replace the temp sensors if it happens too frequently. also, during the winter when the heat is on full blast, it tends to get very hot on the ceilings. is there enough air flow in the room? lastly, make sure they turn them off at the end of the school day. this will lenghten the life of the power supply and the lamp.
Check that the power cable is plugged in and that the power button on the projector cabinet or the remote control is on. • Ensure that the lamp cover or lamp housing is installed correctly. • Check to see if the projector has overheated or the lamp has reached the end of its usable life. If there is insufficient ventilation around the projector or if the room where you’re presenting is particularly warm, move the projector to a cooler location.
It sounds like it is overheating. Are the fans all working? If so, try opening the casing and blowing all the dust out with a can of air from Staples/Office Depot. If the fans aren't working you may need to replace them.
