What if the projector image has no signal?

The reasons why the projector displays no signal are as follows:

1. No signal source input;

2. The signal source is not switched;

3. The signal line is broken;

4. The projection board is faulty.

Solution: First, check whether the input signal source of the projector is switched to the existing signal source; Then, check whether there is a problem with the signal line, and check again whether the external signal source outputs the signal normally.
