Question about BenQ Joybee GP1 DLP Projector
Hi, lots of dead pixels tells me I need a new dmd chip. But which one? What's it called?
Posted by Anonymous on
It's chip number 8560-502AY.
It's hard to access. Remove two screws rear of case and two screws bottom of case to remove the lid. Remove three large screws from mainboard - one at the rear in front of the input port, one to the left of the projector lens, one deep below some blackout tape in the front center of the board. The entire mainboard assembly will now come out. The DMD sub board is to the left of the lens. One screw on the bottom holds it to the main board. The DMD subboard can now come carefully off its connector. The DMD can now be popped off the front of the sub board by using guitar pick or similar.
