White Spots on Projector Display Repair

Are you seeing white spots on your Xiaomi Mi projector screen?  Is it a VAVA 4K Ultra Short Throw Laser TV, Fengmi 4K UST laser projector, or a Wemax Nova 4K UHD Laser Projector? All these 4K laser projectors rely on Texas Instrument digital light processing chip [DLP chip] 
These DMD chips are vulnerable to excessive heat which leads to degradation of the DMD chips, resulting in white spots. These chips can only be replaced as the chips are irreparable

Vertical Lines on Xiaomi Mi Projector Screen

Another common issue with 4K UST laser projectors vertical or horizontal lines on projector displays.
This is due the degradation of the DMD heat sink which causes the heat sink to bend, thereby causing loss of contact between the DMD chip and the DMD chip LGA tray. When this happens, the horizontal lines get burnt-in onto the chips.

All 4K UST laser projectors are very compact in design.  These machines have four fans. The DMD cooler fan is smaller that the other 3 fans and often conks out. Also when dust and soot become heavy on the fans, their efficiency become compromised. This leads to overheating which in turn may result in intermittent shutdowns and the failure of the DMD Chip.
