Customer Question
Hi Pearl, I purchased...

Hi Pearl, I purchased a Canon Legria HF G40 back in July from John Lewis. Didn't use for a while due to being very undigitally minded. Just had two x 2 hour lessons on it and we seem to have found a problem. As I am a trainer and coach I need to play back the videos to my clients. The audio jack goes from the camera to the back of my projector and records fine. On playback when the video comes to an end, a high pitched sonic sound which is loud and will definitely upset my clients. Canon state this is a fault of the camera. I am not sure it is and think a technician will understand better. Can you help please.

Technician's Assistant: Who makes your camera?

Canon

Technician's Assistant: What have you tried so far with your camera?

Tried to playback taking lead out from camera and projector. Noise still there. Appears to come from the camera not the projector.

Technician's Assistant: Anything else you want the Camera Expert to know before I connect you?

No that's the simplest way of explaining what is happening. Thank you.

The high pitched squeal may be due to a bad ground connection.

Try using a different cable, or test the camera on a different projector and let me know if the high pitched noise stops?
