Half inch crystal/ solid white vertical line on screen

The best that you can look out for is to look for GROUNDING problems, loose connectors or faulty cables.
Start by checking out all cables . connectors and see if the power supply ground is well fitted to the chassis. The video or the PC connectors also must be well grounded to the main board , Look for some crack or dry solderr joints in these connectors that could bring these picture noise lines.
Howeverr if you are not able to see or get across these simple problems, i would liike to advice you to try for a exchange which will save you a great deal. Be careful not to damage the WARRANTY SEALS as the dealer may not be helpful.
I hope my advice helps you to decide. Good day

lamp fault i say..

if the gray lines are equal and perfect, I would say this is the graybar resolution setting and would change the screen ration to a different setting to correct.

the resolution doesn't match. reset the projector settings to factory default and make sure the settings are correct, and if the projector can handle the digital signal. you can also try swapping the cables.

Hi Ronnel

This is a common Mainboard failure on a Projector.

The unfortunate thing is that the Mainboard will either have to be repaired or replaced.

Hi there

This is most probably a Ballast ( lamp's powersupply ) problem.

Make 100% sure that this unit is out of warranty because InFocus Projectors come out standard with a 2 year warranty.

Try using a different cable.

If the response is the same on a different cable , then the Mainboard might be at fault - this machine should still be under warranty and the warranty will cover repairs.

Get the Mainbaord replaced

I had a smililar problem after taking it apart i realised that i had screwed my mount skrews into the video main board and cracked it along with a few soldered wires, if you havent done any physical dammage to it try a firmware upgrade
