Hi
My last-ever VCR is a Sony SLV-SE730 and wouldn't you know it, just as I am about to transfer my last VHS's to DVD, the Nicam starts dropping out. Otherwise the VCR is in fine condition.
Symptom: most of the time the audio plays as mono, but occasionally Nicam starts working, usually with faint repeated clicks in the background and a reduction in volume.
I know its not the tapes themselves, since tapes that I previously transferred OK now show the problem. The audio head is clean and unworn.
Looking at the circuit board, there are just a few all-in-one chips and no pots to for me to tweak.
Does anyone have any ideas about what I can look at to fix this? Failing that, can anyone point me to a downloadable circuit diagram or service manual?
Cheers, Marty
