Electrical Problem? Projector works, but buttons don't.
The projector works and displays an image (ie: the bulb is good), but the problem is none of the buttons on the projector work at all. As soon as the power cord is plugged in, the projector turns itself on and is stuck on Input 3. Nothing else works.
Menu, Keystone, Blackout, Input, even the Off button do not work. Using the remote does not work either. The only way to power down the projector is to unplug the power cord.

Many projectors shut down if they cannot find anything attached to them.
Make sure you have a computer attached and sending an image out to it before you hit the projector reset button again.
It's a bit like the chicken and the egg since some laptops won't send an image out the cable unless it senses a projector, and the projector shuts down if it does not detect an incoming signal fast enough.
Your bulb is going out. replace the bulb and you should be fine. Just remember to set back to defualt settings before your change the bulb out and make sure your give the bulb time to pre-heat before you turn the project all the way on.
1.Press the MENU button to display the menu screen, and
then press the F or G button to select the OPTION menu. 2. Press the ENTER button, and then press the F or G button
to select LAMP RUNTIME. 3. Press and hold the ENTER button for approximately
3 seconds. The confirmation screen, “LAMP RUNTIME
RESET.” is displayed and select OK. 4. Turn off the power.
This will reset the cumulative usage time for the lamp
unit to zero.
***Here you go and best of luck!***
If you replace the lamp but do not reset the lamp hours then the projector will not ignite the lamp to stop it blowing up the lamp and causing further problems. You can reset the hours without the image, on the x2 version you turned on for 1 minute then held down the volume up and down buttons for 10 seconds but all versions vary. The infocus website can usually tell you how though you may have to look for it a bit. Failing that try a firmware update available from the infocus website that should erase its brain so you can start again, hopefully you have kept the original leads it was shipped with to do this otherwise it will cost you another £20
1) Press the RESET button on projector for 3 seconds or remote control TIMER button for 3 seconds and display the total lamp used time. 2) Press the RESET button on projector or remote control MENU ON button during displaying the lamp used time. 3) Select the ?0? on the screen using the MENU ( ) button or DISK PAD.
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 have changed the bulb on my LG projector recently. I found the rotating colour wheel to be full of dust. Upon opening the cavity where the light is redirected and reflected onto the imager, I saw all mirrors also had a layer of dust. I don't think it was so dirty that it affected the brightness of the image, but I cleaned it anyway using an earbud. I cleaned both sides of the color wheel as well. You need to be careful in working with the optics of the projector!
