About a week ago my 3-year old Sammy DLP started flickering at a fixed point at the top of my screen. It looks like two individual "pixels", one right above the other. They appear white from a distance, but upon closer examination, they appear to be red and green in color. After searching through a few forums, I couldn't find anything that exactly described this problem, so I came to the decision that it was most likely the DMD board beginning to fail. I found the replacement part online for $50 and swapped the boards out without any difficulty.
Unfortunately, the problem persists and I'm back to square one. I was comfortable with spending $50 on the DMD board since I have 30 days to return it for a refund, but I don't really want to be shelling out a ton of money on more esoteric parts that may or may not fix this issue. Does anyone have any ideas on what could be causing the problem? Below is a short video I took that illustrates the problem. Thanks in advance for the help!
