Please try following these suggestions for working around the issues encountered:
1. The projector has overheating protection function, first of all, make sure that the projector air inlet and outlet are not blocked by anything (confirm that the three sides of the projection (left side, right side, and back side) are more than 10cm away from each other without blocking), if the above happens, the projection will slowly turn black from the middle part until the projection goes out)
2. Please make sure that the fan is running normally (normally put your hand on the air outlet if there is no obvious wind blowing out, the frontal fan is not working because the air outlet is behind the projection
3. Please pay attention to whether the local mains voltage is too low or too high or fluctuates too much.
