SONY VHS VCR SLV-SE730 NICAM DROPPING OUT
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 |

However the video heads are good, picture playback is excellent and manual tracking adjustment doen't solve it. Any more ideas please? Cheers, Marty |

Cheers, Marty The video heads may be good but the audio heads on the head drum can be dirty or worn. Start with a proper cleaning. |
