When I switch on the projector and connect it up to the laptop, the bulb comes on and gives me a short display of changing colours but nothing else. I don't get a menu or input from the laptop. The connecting leads seem ok.
It seems, so the main LCD has been crashed, or not get power, or something else. The changing colours means, i think, the lcd get one picture, but then nothing. So, see the cables, inside the projector too, and see the lcd, perhaps you will find some problems.
i hope, that help you..

1st of all you need to connect the projector with your laptop turned off. One the laptop has finished booting and loading windows. Hit the Fn+f4 or f7 key to switch between the displays then you will get the display.
But if this also does not give display then you can check with the projector with Video INPUTS (Eg. Input 1 / Input 2 etc.,)
you might need to turn off your computer .
then connect the data projector
and turn on data projector
then turn on computer
hopefully it detects the data projector is connected and switches windows to duplicate projection
On my P.C. F4 key in windows Switches the display manually to duplicate, alternate screen or pc screen only or projector screen only.
As I am not familiar with Apple this support article below might explain the switching of display outputs available on Apple Mac.
By nothing do you mean it does not power on? Is your laptop on? Does it have an image on the screen?
Most of the time, this is easily fixed by holding down your function key and pressing one of the F keys. Different laptops use a different key, but you are looking for the CRT/LCD key.
So, press and hold function + CRT/LCD and you should notice a change. Be patient as it sometimes takes a moment. There are 3 settings here. One will give you a display on your laptop but not the projector. One will give you a display on the projector but not the laptop, and one will give you a display on both. So if the first time you press function + CRT/LCD you get a change but it's not what you need, try it again and cycle through until you find what you want.
The light bulb must be seated in perfectly, otherwise it won't see a connection and won't come on. take the bulb out, and make sure the connections don't have any dirt on it. Anything that can obstruct a connection. Give that a try.
The projector should have a cable similar to the monitor cable that would normally be hooked into the computer. The cables work the same and the one coming from the projector will use the same port as the normal monitor cable. Make sure that there is a good connection on both ends -sometimes one or the other get moved and the connection is lost.
Once the cables are hooked up, the projector should be turned on. Normally the projector will soon begin a startup routine and will cause an image to be shown on the screen. You can focus the image during that time.
After the image goes away you should be able to display whatever you want from your computer's software.
Normal problems in doing this are: leaving the lens cap on the projector, having a burned out bulb - once the power is turned on for the projector, it should cause the bulb to come on. Some models have a power on switch and a display on switch that must both be pushed to make the bulb light up.
I discovered that my laptop supports two monitors and the projector was acting as monitor #2. By changing the priority of the monitors I have got the information I need on the screen, but now not on the laptop. However, I can work the two from the screen and that will suffice for the moment, until I can find a way of getting the information on both!
I had one 3300MP and removed/replaced the bulb to dust off as it was overheating. There is a small metal like switch that resets the bulb replacement (physical switch - take a good look) -- This helped to reset the first time I did this, but doesn't reset the hours on the chip.
However, since this bulb was problematic for me, I have done this a couple of times and since has stopped powering the bulb now. So, thinking it was the bulb, I replaced the bulb, -- No good... So, thinking it was the projector, I bought a new/refurbished one on ebay -- tested the NEW bulb - NO GOOD. now I have TWO PROJECTORS, THREE BULBS and NOTHING THAT WORKS...
