What to do if the LED is not lit or flickers on my Mitsubishi Electric MELSERVO MR-J2S- A Amplifier?

If the LED on your Mitsubishi Electric Amplifier is not lit or flickers, there could be several reasons: * A fault in the power supply voltage. This issue will persist even if you disconnect connectors CN1A, CN1B, CN2, and CN3. * The servo amplifier itself may be faulty. This issue will also persist if you disconnect connectors CN1A, CN1B, CN2, and CN3. * A short in the power supply of the CNP1 cabling. Disconnecting connectors CN1A and CN1B should resolve this. * A short in the power supply of the encoder cabling. Disconnecting connector CN2 should resolve this. * The encoder is faulty. Disconnecting connector CN2 should resolve this. * A short in the power supply of the CN3 cabling. Disconnecting connector CN3 should resolve this.
