Sanyo Projector Problems

[ICTNUT]

I am having issues with the following Sanyo Projectors:

SE10
SU32

Lamps are Ok and everything seems fine however if you turn them on and do not have anything connected to them they stay on for as long as you want then if you connect a source i.e. a pc and select that source the projector will show for about 2-3 mins and then turn off.

Anyone experienced this at all...?

not sure what the suggest, i take you have check the normal bits.

I would check cabling,
the filters are clear,
and the screen resolution is within the projectors range,

Anything else im not sure about...

Hi i would suggest it is an overheating problem, with no image they show a blue screen, they run much cooler with this (thats why its blue) if you put an image on and it then shuts down it may be overheating try opening the menu see if it does the same, or display a blue image from your computer see if it stays up?
What is the lamp age (in hrs) is it possible either have ever been turned off with out cooling first?
