1. The input signal lamp is damaged, or other faults (EDID
chip damage, etc.).
2. The input signal light is damaged, or other faults (computer
graphics card problem, device resolution problem, secondary
device problem, and signal line problem, etc.).
3. When there is input (the input indicator is always on) and
no output (the output indicator is flashing/off), check whether
the computer graphics card has output. You can connect the
graphics card output to a monitor that can be used normally
to see if there is output. If several output ports are normal,
you can exchange the normal output port with the abnormal
output port. After the exchange, the abnormal port can
output normally, it may be a problem with the output line, and
the output line should be replaced.
