1)
SYMPTOM:
a. The power switch is set to on, but the console does not light up.
2)
SOLUTION:
a. Check the power cord’s connection.
- If the power cord connected well but the console doesn’t turn on, try a different power cord.
b. Check if the outlet is well.
- If it is not, please try a different, functional outlet.
c. Check if the MCB has power. There is a red power LED on the MCB that should be lit.
d. If the MCB does not have power, check the connection of the power wiring from the power receptacle
to the MCB. Use
a multi-meter to measure AC1 & AC2. The AC voltage
should read 110V or 240V,
depending on your location’s standard voltage.
- If AC voltage value is standard, replace the MCB.
e. If the MCB does have power, check the connection of the console cable wire at the MCB and UCB.
- Remove the console cable from MCB, and use a multi-meter to measure the DC voltage between the
“GND pin” (Pin 1&2) and the “+ 12V Pin” (Pin7 & 8). DC output is normally around DC 12V. If no output,
replace the MCB.
- If output is around DC 12V, check the console cable. If it is defective, replace the console cable.
- If the console cable connections are all good, replace the PCB.
