How to Troubleshoot a Sony Stero CD Player Power Supply

If you're having issues with your stereo CD player's power supply, the unit won't function.

If you notice your Sony stereo CD player randomly shutting off or refusing to power on, there may be an issue with the unit's power supply. Troubleshooting a power supply also gives you the opportunity to check it for wear or damage that could present a major safety issue. Checking your Sony stereo CD player's power supply is quick and easy to do.

Difficulty:

Moderately Easy

Instructions

1. Disconnect the power supply from the wall outlet and, if possible, disconnect it from the back of the stereo CD player (not all Sony stereo CD players will have a detachable power supply).

2. Check the power supply for any damage, fraying or chewed wires. Do not use the power supply if it shows serious physical damage; it needs to be replaced.

3. Compare the operating voltage of the player to the operating voltage listed on the power supply, making sure they match. Locate the operating voltage of the stereo CD player on a nameplate on its back side.

4. Reconnect the power supply firmly to the back of the stereo CD player.

5. Connect the power supply to an electrical outlet, attempting to use a different outlet if the stereo CD player still doesn't function while connected to its original outlet.
