Half inch crystal/ solid white vertical line on screen
I have an InFocus IN72 Projector, when it projects on the screen a half inch vertical crystal line appears on the left side of the screen. Some times this line become solid white, and it nevers goes away. I'm not sure if there is something wrong with the projector or I need a new lamp.

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
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.
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
