If it is a single line, one element burned out on the LCD. If it is a wide band, the LCD or the element driver is defective.

Hi Ron usually power down issues are caused by faulty power supplies especially if the projector looses power completely however the logic board could be protecting itself if it detects a fault such as a fan not working either way it is not recommended that you try to fix it yourself unless you know what you are doing, but it may be worth removing the cover and checking that the fans are working and connected properly, occasionally the lamp can be at fault especially if it has been used for many hours if the projector tries to power up and you see light through the lens and then it looses power its probably the psu at fault, if it powers up then goes into standby of fault then its most likely a logic issue. I hope this helps Regards Ant

Does your projector take lot of time to shut down? May be because it take a lot of time to cool down.
The main culprit would be dust, blocking the air vents/air filters. Use a 1/4 inch paint brush to clean them.
