How-to deal with common projector Issue like no image, image is blurred, low brightness. Here are some usual ways to repair your projectors:
Distorted image
1. Restore the factory prefabricated mode
2. The cause of the failure of the projector motherboard
3. The cause of the failure of the control board
The image is blurred
1. The lens adjustment position is not correct, adjust to the best position.
2. The position of the combining lens and optical components is incorrect, the optical components are dusty, and various convex lenses are damaged.
3. Lamp aging
There is no image of the grating
1. The malfunction caused by the malfunction of the driving circuit.
2. The main board is faulty, but the CPU circuit of the main board works normally.
Low brightness
1. The cause of the failure of the light path itself
2. The cause of the aging failure of the light bulb
3. The failure of the lighting board caused the power supply voltage and current of the light bulb to become low The lamp emission luminance decreases
grated nonuniform
1, polarizer, mirror integral, uniform light microscopy, bulb aging and other reasons to be played fault
2, there is accumulation of dust on the optical path
3, the convex fault damaged
dead pixels
1, the LCD -PANEL has bad spots
2. DMD chip has bad micro lenses
3. There is dust on the light path
No sound
1. Poor interface contact, speaker damage
2. Pre-amplifier circuit building failure
3. Audio power amplifier block damage
