The projector turns on and off but none of the other buttons work. I have tried using the remote and the buttons on the projector but these are not working. So there is no way to choose a source or view the menu items.
This is apparently a common fault and the unit must be returned to a service centre. Theyll put in a new motherboard for it and unless its under warranty this might actually be more expensive than buying a new unit.

Put the projector on. While holding down the Menu key on the projector, press and hold down the Menu button on the remote. Keep both buttons pressed for a count of at least 5 seconds.
When the Service Menu pops up, release the Menu button on the remote control first and then the one on the projector after.
Now you're in to the service menu, you need to find out which button on the remote brings up the Lamp Timer Reset function. This is where you're going to have to do a bit of trial and error. With the TVs, the remote button was the Mute key. There isn't a Mute key on the projector remote, so try the Lamp key first. If that doesn't work then try some other buttons. Here's the method.
While holding down the Enter/OK on the projector, press and hold the Lamp key for five second. If this works then the lamp timer reset box should appear. Release the remote button first, followed by the unit button.
Press Enter/OK on the remote to reset the lamp timer. If there's an On Screen Prompt to confirm, press Enter again.
Press Exit on the remote to come out of the menus.
Warning: Don't reset or change any other functions. The service menu isn't the place to be tinkering around with stuff you don't understand.
Use the remote control and press the MENU button and select the OPTION with the UP and DOWN arrow buttons. Press ENTER button and then press UP and DOWN arrow button to select CONTROL PANEL use LEFT and RIGHT arrow button to VALID the control panel buttons
If you have a loss of the remote control while the control panel is invalidated.
Press and hold the MENU button for 2 seconds with pressing the ENTER button to enter the MENU and VALID the control panel.
If you are connecting to a laptop then you may need to hold the function button down and press F1, F2, F3 etc. there should be a sign with the latop on there and a sign with an external device (monitor,PROJECOR)
