mine does the same thing but i can see the whole screen it's just half height full width, above solution about zooming to 1X is what i've been doing to fix it for the last 6 months, needs to be done every time I turn the power back on. Anybody know of a more perminate fix?
Now my power supply has gone have the projector in pieces, found a failed on transistor but because it's over heated can't read of it what type it was....
Already replaced two blown diodes in the main H-bridge
Looks like one coil will need rewinding.
If anybody has one in pieces I would be great if you can help me work out what the blown transistor was.

I don't think it's the bulb. Sounds like an LCD panel issue. Maybe one or more of the 3 LCD panels is either not working right or the unit has been dropped/jarred and the panels have moved (All three have to line up right optically to give the right colours). You need to take the projector to a qualified service centre.
I hope that solves your Problem, If so kindly accept it.
Thank You, Arjun.

The normal cause of lines across the LCD of a laptop is a damaged video
cable. The unusual cause would be the video card itself.
To determine which item is at fault, you need only attach an external monitor to your laptop's video-out, and then swap your monitor view to 'both' or mirrored (usually just the function key (FN), plus one of the Fkeys...look for an off-blue picture of a monitor on the Fkeys).
If the lines across the screen also appear on an external monitor, then the video card is damaged.
If the lines only appear on the laptop's LCD, but not the external monitor, then just the laptop's internal video cable is damaged.
Hope this helps.
