Have Infocus X2 projector. When on a dark shadow line appears down the left side of screen. Could it be a bad lamp?


no it is not lamp problem. it must be light tunnel problem.
after lamp there is tunnel for light travel, made from 4 pieces of mirror.
this tunnel is glued. glue tend to break in time so the tunnel is no longer doing its purpose.
open this part of projector, there should be 2 little screws holding it. repair it by reposition mirrors and glue them from outside by little drop of temperature resistant and elastic glue. that's it !

I only get a blue scree on my Infocus 340 so therefor I cannot see the images well.


give more details , when you get blue picture ?
blue screen is indication that no signal is coming to projector so check your cable and try different connection, there is svhs and dvi input, try both.

I have the same issue minus the clicking


check the lamp for bulges, black spots, or fogging. if that's ok, check the colorwheel. if that doesn't spin, the lamp won't light. if they are ok, replace the ballast.

Hey scottydogg, not much inormation there, have you tried to download software from the actual compnay itself, and then install it to your pc, and then go from there, nearly all of the big companies, do allow you to download software in relation to a product you have purchased???

maybe put a little more inforamtion in your post.

Hope you get it sorted :-)
