This link allows you to download the manual. if you need it; http://www.usa.canon.com/app/pdf/projector/lv7215_7210_5210_manual.pdf page 41 especially worth a look page 43 gives all details for lamp replacement if you still think is the problem. Almost certainly the problem is to do with overheating - which is either a bulb problem or a malfunctioning fan. See if the fan runs when you turn it on and check it is clear. Hope this helps :)

Sounds like you have an overheating problem. Maybe a bad fan? Also you may have a bad connection to the "bulb".

Possible cause is overheating.
Do you hear the fan working?
What happens when you use the lowest level light output?
Does it run longer?

Also possible cause is a faulty temp sensor.
AC wire connection may not be firmly pressed in socket.

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.
