The screen of my Optoma 141x projector(1300 hrs usage) shows tiny black dots all over, especially on the right side. Please suggest what it means and what I need to do.
Thanks so much for responding. I also think the dmd chip could be the problem but I have my doubts.
As you can see from the image almost all the dots are black, almost none are white. If DMD chip was the problem I should have got numerous white dots also.
