OT! DIY fix? VCR not (re)-recording sound

Audio recording head needs cleaning possibly?

Look at the head and see if its pitted with tape dropout? preferably with a magnifier. Or just clean it with meths and see if that restores the recording audio? if it doesn't make no diff then its possibly an electronic component fault?

I wouldn't have thought so as the previous audio is still there but cheap VHS machines have a full tape width erase head seperate and before the rec/pb heads. This should wipe the previous audio...

Has this machine any dubbing features? Maybe audio record has accidentally been switched off in a menu or hardware switch somewhere under a panel. Similary check settings for Hi-Fi/linear audio mode(s).

Agree with Dave on this one. IIR the early JVC were the rolls royce of vid's and had an audio dub facility with a small slide switch at the side of the front input sockets, Failing this it sounds like the audio switching amp has gone faulty as you are not recording new audio (if i read your post correctly)

Rolls Royce of VCRs? Mine can't be an early model then ;-) No sockets/ switches apart from 2 scarts (only one is in & out, other just input), the RF loop and a 3.5mm jack output for some optional IR satellite box controller (channel change).

Problem now fixed - acetone on a cotton bud did the trick on the erase and audio/control heads (left and right of the main drum and the delicate video heads). Kept well away from the plastic and rubber parts. Allowed some evaporation time then gave it a whirl. Audio now records :-) Thanks for everyone's input.

Ahem! :-)

Dead bias oscillator or possibly open circuit erase head. I assume it's not HiFi?

Can you see faint ghosting in dark areas of the picture on a newly recorded over tape?

Have you read his latest reply Clint?

My post was written but not sent immediately. I downloaded his fix post whilst mine was being uploaded. Better timing next time maybe.
