Hi there

This could possibly be your Ballast ( lamp's powersupply ) that is faulty.

It will either need repair or replacement.

The lamp may be out. Projectors need high voltage/wattage lamps. They tend to only last 2000 hours or so, which is about a year or two with normal use.

unfortunately, lg won't tell anyone outside of their service center how to do this. they even recommend that you send it to them. it's their way of ensuring return business. sorry.

Hi there

This is definitelly not your bulb.

Check if there is any damage to the colourdrum , if not then this is a faulty Mainboard.

Must warn you that LG's Mainboards are very expensive.

Hi, Normally your connection should work straight out. Pls verify that your dvi output is enabled/activated by checking your display properties. In a Windows based OS machine, right click on any clear area of your desktop, click on Properties. Click on the settings tab, Advanced button. Check on the different abs such as Monitor, display and others. There should be an indicator for dual view or enabling/activating your secondary display unit (which is your projector). Hope this be of some idea/help. Post back how things turn up or should you need further information. It may also be of help if you can provide info on your PC. Good luck and kind regards.
