One channel is not recording properly. Can I fix it?
The L channel input isn't working. It seems to be picking up some low levels signal of some sort every now and then, and on playback there appears to be an almost silent low level recording, but the usable recording is effectively mono (R channel only)
"I just faced this problem and solved myself EASILY.
I have 1 old and 1 new, and this only happens to the OLD one.
This often happens when I insert a line-in plug. It works all ok when line-in. But when I pull out the plug, the R channel becomes either silent or noisy, randomly.
When the problem happens, just PLUG IN AGAIN. Sometimes I try several times to solve it.
*I believe alectronic is right. This problem happens after using the line-in plug intensely."
