Hey all, first post.
I recently bought an Optoma HD33 off ebay and have been having some issues with the picture. When I first powered it up there weren't any problems, but then a few minutes into viewing, the projector started making a buzzing sound. I gave it a couple taps, and it stopped. This continued for a while so I cracked it open to scope it out and see what was happening. Didn't see anything unusual, so I reassembled and started it back up. No more buzzing, but a couple hours later the picture started flickering. Really annoying sporadic flickers that got worse depending on the level of contrast on screen. I will include a short video.
I opened it up again and tried to blow out any dust that might have gotten in the first time I opened it. This worked, until I rebooted the projector. I feel like I'm chasing ghosts here, hopefully someone has an idea of what's going on.
Let me know if you need more info, I wasn't sure how detailed to be.
EDIT: Okay here's the video.
