Question about Philips ProScreen 4750 Impact Multimedia Projector
I actually have a Phillips Fellini 100. The problem started small on the right side of the picture, with a couple of small color bars visible in the picture. Now, this has progressed from both sides to virtually the entire screen. No idea where to begin to try to fix, or even if its worth fixing. Any ideas what the problem might be?
I've got a similar issue with one here. Problem appears to be a defective LCD,in the blue position, as swapping it with the one for green (the middle one) resulted in green bars instead of blue ones.
The good news: the LCD panel is easy to remove.
The bad news: the LCD panel is a NIGHTMARE to re-align when you refit it. I now can't get the green panel to line up properly, and of course the blue one's still faulty!

The panels can't be aligned with the power on, as there's a PCB in the way. You've got to switch off the projector, unplug 7 ribbons, remove two PCBs and a baseplate, adjust the LCD panel position, refit the PCBs and ribbons, switch back on and see if it's any better. Presumably at the factory it's done using a test jig before the PCBs get fitted. Looking at the results on Google the 4750 has a tendency to eat these panels, a shame really.

The Problem seems to be in the RGB Panels.
