Maintenance and precautions for common projector malfunction
Brightness decreases, the picture is blurred
The image projected by the projector appears dark yellow or the color is not bright, or the picture is blurred.
If the projector appears dark yellow or the color is not bright, it is very likely that the bulb has been dead, and you need to change the bulb again.
When the lamp has reached the end of its life, a new lamp should be replaced. When replacing the lamp, it is necessary to reset the lamp usage time after replacing the new lamp. Otherwise, the new lamp will be calculated according to the old time, which will easily lead to accelerated aging.
