Cleaning dlp lens? Or is this on the chip?

There is a distortion on this picture, looks like a stain. Pressing in on the picture, it moves further with the press, so its def. from the projection

The background picture is blue, so the color is actually ok

It's the mirror!

I've tried a microfibre cloth with warm water nothing
Microfibre cloth with 91% isopropyl. Nothing
Paper tower with 91% isopropyl. Little bit

Screw was off the side hole like someone already tried to clean it

carefull on the mirror, it is likely first surface and will scratch very easily, try using a bit of liguid dish soap or a foaming glass cleaner.
