Customer Question

I have 3 Optoma ex525st projectors. One was purchased new. 2 were refurbs bought from Optoma. All have had DMD chip failures, the refurbished units failing first before the new one. None of them were used long enough to even require a light bulb change. I am capable of replacing a DMD chip, but have not been able to find a source for them. Any help would be appreciated. Thank you.

Hi and welcome to Just answer.

Initially, may I know what is the part number of your DMD chip?
