Projector starts up and shows DELL logo, but then goes to a blue screen and says "No Signal - Check Video Cable". I have tried replacing the cable with a new one and also tried connecting it to different PCs. Is there anything else I can try other than a repair shop?
I think I had a similar problem- are you connecting to the right socket.? The VGA on the 3100MP socket is `VGA out` you might need to connect to the `DVI monitor in` socket ,possibly needing a male DVI connector that connects to a male VGA lead.(Maplins , if you are in UK ,sell one for about £10)

Re: Dell 3100MP Projector - No Signal Check Cable
Make sure you have the right input source selected. It may be looking for a signal from some input other than the one you're connected to. Beyond that, if it truly isn't seeing the input then you'll need to have the projector serviced.

In most cases this problem is cured by enabling the external VGA (or monitor) ouput on the laptop. The quickest way is to reboot the laptop with the projector turned on and connected. Usually the laptop will detect an external display is attached and enable the port.
It is also possible to manually enable the external display port. It varies from laptop to laptop but look for the "Fn" key at the bottom left of the keyboard, usually coloured green or blue. You should see a row of icons on the top row of "F" keys which is in the same colour. Look for the one which is either a monitor, or possibly says LCD or CRT.
Hold down the Fn key and press the key you located in the last step. There is usually a delay of a few seconds and then you'll find something may happen. Usually the external output will be turned on alongside the local (laptop) display. Repeatedly following the last step cycles through all available configuration options, including both on, local on, local off, external on, and external off.
This should fix it. Make sure that the correct input is selected on the projector whilst doing this. It will be labelled on the projector and it should display the same input message on screen.
check that you have a signal going out of the monitor socket on your lalptop.
On Dell with projector connected and switched on, press the blue fn button bottom left usually, and while holding, press one marked CRT/LCD, (maybe f8) this will cycle to the following.
laptop only, laptop and monitor, monitor only, while holding Fn button press until you have desired outcome.
check the heating of your laptop. it more heat chek your fan or cfu fan, if work properly.. shuting down is a lot of cause. over heating, fan not work properly case over heating... processor.. or board..
the lamp is not at problem, but the dlp engine is at fault, u may have to replace it.since u bought it 2nd hand,it is not worth changing the same as it will cost u more than ur buying price.when u plan to buy ur next projector, make sure u buy a new one as it will come with a fresh lamp & manufaturers warranty on the unit & at 4000 / 5000 hours of projector usage is guaranteed!
One problem may be that you must tell the PC to send the signal to the external monitor. Usually, if you hold down the function button and hit the F5 key you will see several options on the screen. (Other laptops use different function keys. Look for the one that shows two tv screens. You want the option which shows the laptop and the external monitor.) To advance between options, you hit the F5 button again and it moves over to the next option.
My computer needs me to lower the resolution on the laptop in order to send the signal to the projector. If you also need to do that, you can do it in Control Panel, Display, and Settings, and lower the resolution on screen number 1.
Doing both of these things should work.
Also, confirm that it is finding signals by hooking it to a DVD or video and see if it finds the signal through one of the other ports.
