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.
What does the DMD chip look likes? Where I can find it? Why is not possible to have the chip only with the serial number of my projector?
Optoma should be able to tell you if you call their tech support line. They may not want to. Here is a video showing how to find the DMD in a Optoma its not my video though.http://youtu.be/uJpGvrz3yR4..
Thank you very very much for your help!!!! Now I will try to repair alone.
