Question about InFocus ScreenPlay 4805 Multimedia Projector
I have ballast problems with several X2 X3 projectors and even a C180 (Proxima) although with different ballast power layout. My X2 units mostly seem to have blown a pair of output FETs (2SK3568), but that is only part of the problem. One unit powers up, but just won't strike the lamp. Installing a good ballast power supply board fixes the problem, but I can't find any place to buy or repair these without sending the whole projector in for repair.
Perhaps it is time to trace out the schematic of these boards and have someone start repairing them at big profits.
