The service was quick and simple, finding the service manual easy and it appears to be the original with colour schematics. It contained the info I was after and so sorted the problem.
I have copied it to CD and attached the envelope to the inside back cover of the owners manual. Good manual and excelent service. Robin Wood, Wood Electronics, New Zealand.

This Service manual is very well scanned and its clean to read, no any anti-theft words that un-english could understand. I got my CCD600 working with this manual and it´s clear shematics :)
