For some smaller-sized camcorders, it is normal for a small amount of motor noise to be recorded on the tape. This is due to the compact size of the camcorder and microphone. Whenever a tape is in the camcorder, the motor that spins the recording head is active, causing a slight hum when recording.
There are other situations, however, that could cause a humming sound. Any externally-connected lights or microphones may cause the issue. If using an AC adapter to power the camcorder, the electrical outlet or even the AC adapter itself may be the cause.
Follow the steps below to troubleshoot this issue.
NOTE: Because each of these steps represents a possible solution to this issue, check if hum or noise is still recorded after completing each step.
- If an external light is connected to the camcorder, disconnect the external light.
- If an external microphone is connected to the camcorder, disconnect the external microphone.
- If powering the camcorder with an AC adapter, try plugging the AC adapter into a different electrical outlet.
- If plugging the AC adapter into a different electrical outlet does not resolve the issue, disconnect the AC adapter from the camcorder.
- Insert a fully-charged battery into the camcorder.
If disconnecting any external accessories (lights or microphones) resolves the issue, then the accessories should not be used with the camcorder. Also, if the humming continues when using the AC adapter in different electrical outlets, then the AC adapter may require service.
The troubleshooting steps listed above should resolve your issue. If you have completed all of the steps and the issue is not resolved, service may be required. Begin the procedure to send your Sony product into a Sony facility to be repaired.
