Help! I'm trying to open an old Philips Proscreen 4600 projector. Can anyone shed some insight on how this beast comes apart? I've got the four screws out of the bottom and the front of the case is seperating, but the back of the case seems as tight as ever. Is there anything I'm missing here?

Thanks!

Keep looking for more screws, they often hide a few under stickers to make it obvious that someone has opened the box (and voided the warranty)

Also, many plastic cases have clips holding them together. Sometimes the locations of the clips are marked by arrows or something, sometimes they're not. Try carefully sticking a thin spade screwdriver into the edge of the case at an extreme angle (as far from perpendicular as possible). Try various places on the case, also try from multiple angles. Of course, be very careful whilst doing this, as there are often fragile parts right behind the plastic.

If the 4 screws you mentiond were all on one edge, the clips are probably on the opposite side.

i found INCREDIBLY a user manual i think it can be useful
