MALFUNCTIONING Yaber Model:Y31 Video projector.

The fan is not working correctly and begins making a sound that causes the video projector to overheat and a large black spot will appear on the top right and grow to the entire right screen until the fan turns on and cools the projector that lets the spot cool down and disappear.

The biggest feature is the Y31's innovative 4D Keystone Correction (± 50° for horizontal and vertical correction), auto vertical correction, one-click Restore, and one-click to Brighten function which is not possible on other projectors.
