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.
Is this a good question?
