Step 3Testing
Now we can test the screen on the overhead projector.
1) Lay down the screen on the overhead projector. Use something between the LCD screen and the glass plate to create some space. Watch out for scratches on the screen.
2) Connect the screen to the power supply, LCD controller and OSD controller.
3) Connect the LCD controller to your computer.
4) Turn it all on to test it.
Do this only a few minutes !!! Otherwise the screen gets very hot and will die !!!

We just finished our DIY-projector until this step. Everthing works, but the light is really bad. We have an OH-projector with quite a decent lamp so it seems strange. Someone who can support us?
1. Make sure everything is clean. The bulb, the mirror (if your OH uses one), the glass pane, the screen, and the lenses and mirrors in the focus unit.
2. Make sure there aren't any of the clear or (especially) opaque plastic sheets on the LCD panel. These were there originally to help diffuse and spread the light from the backlights but they cut down on the amount of light that makes it through the screen.
3. Play with the display controls on the OSD controller. (Brightness, contrast etc.)
4. Leaking light. Make sure you aren't letting any light out of the edges of the screen. Also make sure the room you are projecting in is dark.
If none of that improves the brightness you could try a new bulb or wiring a second bulb.
