7. Common Failure Analysis and Troubleshooting
Failure phenomenon Failure cause Solution
Power on, the front
panel display screen
and power indicator are
both off Switching power supply
couldn't
start;
equipment; internal DC
power supply is not
working.
Check if the power
supply is normal (should
be AC: 110V-250V). If
the supply voltage is
normal, it could be a
failure
of switching
power supply module.
