A student tripped and unplugged the projector. Now


The projectors usually keep a fan running for a cool down time after the switch is turned off. It's possible that there is that there is a burn mark on the bulb or other part due the sudden power drop. At least have good look at the bulb and immediate area to see if there is any sign of visible damage.

What causes white vertical lines on dlp projector?


Possible fault on the mother board as there are noise on the LCD display. You might need help to sort this out if the fault does not clear even after the lamp works for some times.

Lp70+ display shows a solid black vertical line


the light tunnel is either collapsing and blocking the light going through it (and needs replacement) or the vertical/hoizontal adjustment of the tunnel. if you take the lamp out and move the colorwheel (with a pencil eraser) to the clear section, you should be able to see a square through it. if part of the square is blocking the middle, the tunnel needs replacing.

by the way, on some projectors the light tunnel is called an integrator rod.
