3100MP DELL Shuts off after minutes of use

My Dell projector 3100mp shuts off after minutes of use. When I turn it back on, it shuts off even quicker than the first time. The symptoms seem to indicate thermal shut off issue. The bulb works ever time, it's just the unit that turns off. Is there a simple fix of changing a board? Or is the bulb near the end of its life and is it overheating causing the unit to shut down? The shutting off started doing this after I connected my new blu-ray system and started using the composite 1080i connections (also, there is green around my boarders that i don't know why ... maybe you can tell me what that is too? It may be due to the keystone adjustments as it is only in the keystone slivers on the sides). Someone said I may be overheating it since the blu-ray is a 1080p and it is not compatible with the 1080i on the Dell unit (not sure I believe this).

Sounds like you have an overheating problem. Maybe a bad fan? Also you may have a bad connection to the "bulb".

We have had two and they both did the same thing. We sent the first one back because it was still under warrenty, they sent us another one, it does the same thing.

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.

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)

SOURCE: Hi, is Dell 3100MP Projector

Hi,
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.

Bad SMT connector on main board


mmm. a very small tipped soldering iron
while working under a mantis pcb magnifier.
you'll need a steady hand.....
don't however try to remove the sm connector, this will probably only wreck the pcb. try to use small wires to make the connections and bypass rather than try to rescue the connector.
