Optoma HD66 projector is a HD projector which comes with 1280×720 native resolution which is an old Optoma projector. I think there are lots of owner of the Optoma HD66 projector have the same problem. That is white dots on screen of this model.
As Optoma HD66 is a DLP projector which comes with a TI technology DMD chip, the chip itself will be aging after a few years of usage. When there are some white dots or black spots on your HD66 projection screen, it may come up more and more in a few weeks. I found there are some people asking if any repair center is able to repair this error or if they can repair the DMD chip. Here, I don’t thin it is a smart choice to ask the repair center or take the projector to the repair center to ask for a solution. They may cost you a few hundred dollars for repairing the white dots error. Or some repair center ever offer more than 900 Euro to fix their projector. It is really expensive to replace a new projector.
However, it is still two solution to fix your Optoma HD66 DLP projector. Too replace a new projector or replace a new projector DMD chip. There will be no more another option. You do not need to search on google if any one who can repair your original DMD Chip or any compatible product such as compatible projector lamp to replace your original. I can 100% sure here in the world, there is no one can repair it unless TI technology and there is no one who can copy the TI technology to make you a copy.
