NEC projector turns itself off after 10 mins

[tl82]

I have a NEC projector that turns itself off after 10 mins of being connected to the laptop. However, if it is not connected to any input, it stays on and shows the NEC logo on the screen. The lamp has only used half of its lamp hours and I am not getting any warnings on the screen about the filter or overheating. I can't check if the projector is hot to the touch or if the fans are noisy as it mounted on a 13ft high false ceiling in the school hall and none of the ladders can reach it. When walking underneath the projector a while after it had switched itself off, I noticed that a red light was flashing.

 

Does anyone have any ideas of what could be the problem or am I better off replacing the projector? (it's about 5-6 years old).

5 or 6 years old - with a red lamp shoeing, it sounds like it's decided to give up the ghost. If you Google the model you should find a manual which will explain the warning lamps.

 

We recently had two new Hitacchi units pop bulbs on very low hours. Hopefully that was a case that the bulbs they came with were a bad batch and will all expire whilst the warranty is still active. We have an onsite warranty visit for the second one booked this week and the T&Cs are a bit grinding. Droning on about only being worked on up to a certain height ( understandable I suppose) and that it will be billable at a ton plus if it isn't the fault we reported.

Is it a DLP projector? If so a faulty colour wheel will do this - as we have found out on our old Sahara projectors

I can't even find out what the model it is as the security cage blocks the view!
