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.

Replace lamp


you don't. it's an led light source. if you can get one, remove the 2 screws in the back and the top should come off revealing the light source.

Hi, I have a projector Optoma EP7155 and it appear white and black spot like dead pixel, I would like to know where I can buy a DMD chip with the CCD and how much it will cost. Thank you


global projectors is one source. You need to find out from Optoma the chip you need or take apart the machine and look at it. From China they run about 200 bucks. I've only done Mitsubishi so far.

I have a benq MP670 that i bought i China 3 months ago and i live in Kenya... it has white spot al over the place... but there are many in the right side of the screen... what can i do?


Sounds like the DMD chip is getting bad pixel failure. Most likely the chip will have to be replaced.
If the white spots are well defined and rectangular in shape when you get up close to the screen, then this would confirm the problem.

Just tell your friends that it's snowing in Kenya and the snow flakes are getting on the screen and ask the children to try and brush them off. Make the most of it until you can get it fixed, or get another broken one that has a good dmd chip and swap parts.

White pixels forming on screen and increasing in number. Slight distortion in other spots pixels are extremely bright but small.


This is a problem with the internal DMD chip which needs to be replaced.
Contact BenQ Service,should be covered under warranty.
