Brown smudge/spot on the projection image about 1/6th of total picture
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!

I just placed an order for that part! My projector also has the same brown smudge, so hopefully this fixes it! Same dimensions, so crossing fingers!

I think the most important thing with these little units and the issue with the polarized lens burning is you have to keep them from over heating.
Don’t leave them on when you’re not using. And keep them ventilated with fresh air, a fan, or in air condition.
That said I have not had to replace the glass again since first doing it with the part from aliexpress.com so it may have been a manufacture error in the original glass and unit as well.

Any suggestions on what fan would be good to replace with?

Hi Liz. I’m not sure. Did your fan burn out or are you looking to upgrade?
After changing to the new lens from the link I haven’t had any issues. It’s been I think a year or maybe two. I am pretty careful not to leave the projector on for long periods when not watching something. But I do occasionally watch something for hours at a time and the new lens has been just fine.
