Question about InFocus ScreenPlay 7205 Multimedia Projector
These thin white lines are vertical on image and are in proportion to each other. I tapped on the unit and the lines went away then came back shortly. There is also a 2 inch black bar horizontal through the image as well. Please help.
The black bar is from the light tunnel collapsing. the white lines are from the colorwheel or the main board has a cold solder joint. replace the tunnel and colorwheel and have the main board looked at.
