Be sure you have the right input selected. You might try Auto Search. Then toggle the laptop using the F8 or proper function key to display the output to the projector or in both places.

This is probably a voltage issue with the power supply especially if it is an LP70 type projector. If not it is still a power supply problem that will have to be fixed.

I had the same problem with my LP815 projector, it wouldn't power on the LED lights did do anything. I open up the projector and replaced the fuse, and now it works! Just replace the fuse and that should do it.

Have you tried cleaning the fliters on the back of the unit? It's easy to do. Pull them out, and blow them clean. Also, is the projector well ventilated - mine overheats sometimes and shuts off. Otherwise, sounds like he bulb to me.

the greenish tint is likely the light tunnel being out of adjustment or partially collasped. The image being out of focus is likely the misalignment of the focus tube to the base of the focus tube that screws into the front of the light engine. A technician will have to fix either problem.

without knowing the model you are speaking of, I would have to say try brand new cables.

The light tunnel is collasped or it out ouf adjustment or the mirror inside the lens assy has been jarred out of adjustment. All of these need to be repaired by a technician.

Possible that the noise you seen( Video noise) is ccoming from the DVD player.
Most often the connecctingg RCA cabbles can be have poor shield orr damaged wires. So connect them tight with the ground tight. If the noise appears reverse the plug of the DVD after switching off.
If the fault wont clear, try to use another device on this port to confirm( another DVD player will be good.)
If the fault disappears then the noise is coming from the power supply of your player --possible failure of filter capacitorrs in the power supply,producing transcient voltage.
However if the other DVD also gives this noise, try to ground the projector, if there is no result then it is possible that the Video input socket has a ground failure in the board.( hope there is no issue with the PC)
If there is fault with all connections to the projector then it is possible that the board are not grounded or there is failure in power filtering. Check on power supply.
Hope these tips help you to make the tests.

try peeling what you can off and then go to an electronics store like radio shack and get some aerosol board cleaner like BIO-ACT E37M which is a cleaner good at dissolving or breaking down plastic or FLUXOFF board cleaner and work at cleaning it off with a non abrasive cloth and scraping off with something plastic like a credit card and keep working at it until it is mostly clean and maybe a little hazy looking and then get a new cloth and start cleaning the left over residue off the lens with alcohol until it is clean.

Try to hit the function key that switches between laptop LCD and external monitor. Fn + F8 on Dell, Fn + F3 on Neo and Fn + F7 on other laptop.

make sure nothing is stuck in the fan if you can. it would be helpful to know which fan is not working. the easiest thing to do is to make sure all are plugged into the main board. the next thing is determine which fan is not working, usually it is the lamp blower. at any rate, it will have to be repaired by a technician.

bad power supply

To advance slides in a PowerPoint presentation using an optional remote control, plug the USB cable into the USB mouse connector on your computer
and the USB connector on the projector.

Have you tried the keystone correction. You must have the projector squared/lineup to the area you are projecting.

Hi,
It depends on model of multimedia projector and its performance. If dark picture is only issue then yes, its worth to replace lamp/ bulb.
And if projector is like 5-6 years old model then lamp replacement would be waste of money.
Thanks.
