M7735L recording issue....

[Ianthepostie]

So I've just noticed this issue with my Sanyo M7735L boombox. It records a buzzing/humming noise in the left channel when recording with the built in condenser microphones. Recording from the radio or line-in works perfectly though. Its not overly important as I dont ever use that function, but I'd be interested to find out whats causing it and if its fixable. Here's a short video of the problem in action.

Cheers

Check the wiring for that mic, sounds like a bad ground connection.

Thanks! You were spot on with your diagnosis. The connection from the microphone to the board was a little loose. All good now!
