Once lines start appearing on the LCD its because the screen is starting to go bad on it, the pixels are starting to become defective. Only solution is to replace the screen or replace the monitor which would be cheaper.

I also am having the same problem. at first it only showed up after the projector was on for about 15 minutes. Now I get a purple vertical bar on the right of the screen. I also get vertical green bars spread across the screen.
Does anyone have a diagram of how this machine is assembled?

Current LCD display technology can reproduce about 300 different levels of brightness. Brightly lit scenes or light sources may exceed this brightness range, causing a temporary disruption (artifacts) in the live display. Artifacts are part of the display, but they are not part of your recorded image. If you take a picture while you see artifacts on the screen and then display the picture on the LCD, you will no longer see the artifacts.
