After putting a new lamp in the projector in my PT-AE1000U, it turns off on it's own after 5 to 8 minutes of use. I was told it could be a BIOS setting that counts the hours of use that needs to be zero's...

Generally speaking a lamp timer is just a warning indication and won't shut the unit down. There should be indications of why the unit is shutting down. For example, is the power LED blinking or any other light blinking? My primary suspicion would be either an air flow problem or heat. Check to be sure that the fans are running properly.

Please update this with any additional detals.

Power indicator /red/ and warning led/red/ are lighting after ea 15 sec. a lamp never start and fans goes in OFF mode. I checked power supply lines S5V,S-5V,S16V on the Main Board . I checked unit lamp...

If power indicator light red and warning indicator red flashing than according to user manual :-
The projector has been cooled down enough and the temperature returns to normal. When turning ON the projector the WARNING indicator stops flashing. CHECK AND CLEAN THE AIR FILTER.
Experience:- 1. if the temperature is very low than temperature sensor maybe misbehave.
2. If anyone fan not working
so please you check fans.
(If lamp or lamp ballast unit faulty than after a time period the lamp indicator light ON not a warning indicator. I experience many times if any fan in projector are broken or jamed the temperature light if present otherwise warning light ON or flashing)

My infocus X3 projector won't come on, I get a green light at first and then it turns red. What is the problem?

Well the single re blink of the LED indicates Lamp failure. Though most likely there can be a few other causes for your lamp not lighting. here's the most likely problem if the lamp has not failed.
It could be the lamp power supply (ballast) has failed.
Or if you don't hear the fans running either there is a possibility the "over-temp" sensor has failed.
If the fans are running I would try replacing the lamp.

Take Care!

How to connect to external monitor?

You need to determine the fault first.
Can you determine exactly where the boom came from (the adapter or laptop)?
When you turn on your laptop does the LED lights indicating that there is power to the laptop and you can hear the hard drive spinning as well as the fan?
Do you know the power adapter is OK (you can test it with a multimeter)?
If the laptop is dead then the external monitor is of no use.

The laptop normally has a blue video output connector, usually on the back edge of the laptop where you can connect an external monitor or a data projector. When a monitor or projector is powered up first and then the laptop the display goes to the external video first. You can switch between the laptop screen and external video by clicking the blue Fn + F4 function keys.

LP 240 stopped working. No lights, no fans, nothing.

Please describe the status of the LED indicator. No LED would indicate a failure of the power supply. I can help you with that.
Flashing red would indicate a fan/lamp problem. Some lamps fail prematurely before the lamp hours are up.
If it is the power supply, no lights at all, I can get you running again. These units have fragile power supplies that can burn out with the slightest power surge. A UPS goes a long way to save future headaches.

LED won't come on and only faint hum is heard.

Hi there

You are most probably looking at a faulty Ballast Board wich is the lamp's power supply.

If the Projector makes a really hard humming noise it could be your Colourwheel that is faulty.

The unfortunate thing about a Colourwheel is that you can't fix it , you have to replace it. The fortunate thing is that it is a very cheap part to replace.
