Tip & How-To about InFocus LP220 Projector
To replace the colorwheel:
remove the 4 brass and 4 silver screws from the bottom and the 2 silver screws from the back. through the top vent on the back panel and using a flat head screwdriver, unclip the 3 clips holding the back panel on. once removed, unplug the 2 wire harnesses. remove the top and front panel. now unplug the large wire harness and remove all the brass screws on the 2 power supply boards (also the screw for the ground wire). there is a black clip in the middle of the larger power board. remove the boards. now remove the brass screws holding the metal plate on. once removed, unplug the flat ribbon cable (for the colorwheel). now facing the front end, remove the lamp and the 4 screws holding the lamp housing (with fans) on to the bottom case. remove the tiny black screw on the small circuit board and remove the board. now you can get to the colorwheel. there are 2 small black screws holding the bracket. pull the ribbon cable through from under the fan. replace with new colorwheel and reverse the instructions. the only difference, remove the front panel from the top by undoing the clips. good luck!
