I have a DB T20 that is projecting a brown smudge/ spot on the screen. It looks like it’s on the lcd if I look through the front lens. I know can see the lens is fine. What could it be? Is it worth opening it to take a look? Also it makes a buzzing sound like a fan sticking for first minute on power up then works fine.

Ok So there is a SOLUTION. If you want to fix your little projector you need to order the part below or one of the same dimensions. This part is a little bit thicker than the stock one but if you carefully press it in or widen the side guides a little bit it will fit and work perfectly. I ordered two so I would have a back up. It did take over a month for the part to come. I wrote it off because they never sent an email to say it had shipped, but eventually it did show up. That's ordering Chinese parts for you. Good Luck!
