Question about InFocus ScreenPlay 4805 Multimedia Projector
After cleaning the bulb screens and re-inserting the bulb housing on my SP4805, the fan that cools the bulb does not run and the projector gets very hot. Also, it makes some occasional whirring sounds. The projector operates normally with a solid green LED. Any ideas?
Glad to have been of help with the instructions. Don't bother of getting the exact replica of the fan just get the right size that fits they are usually all 12volts and shouldn't be a problem to find.

Turn the projector on it's back unscrew the 4 screws that are on the front and back grill. Unscrew the 4 screws that hold the bottom case. remove the 3 small screws from the back grill. Remove the focus and zoom rings. The zoom ring can be stubborn to remove. What I do is lever it off by pulling the front grill. Don't try to remove the front and back grill from the top case. It's better to remove them together. When you succeed in removing the zoom ring, lift the the front grill together with the top case up. You should be able to insert your hand to push off the keypad and speaker plugs. When you're reassembling back the covers, separate them by gently prising the front and back grill from the top cover with a flat blade screw driver from the inside. Assemble the top cover first and not forgetting to plug in the keypad and speaker plugs at the back.

Make sure that nothing is obstructing the fan. Try to rotate the fan with your fingers to make sure it is free. If it is, you would be lucky if the fan is at fault because this is rather cheap and easy to find if not it is the main board which is at fault.
