Sony CCD-TR805E Auto and manual focus not...

Hi! I have a Sony CCD-TR805E with auto and manual focus problems: it does not focus at all; operating the camera the focus motor does not turn at all both when I try to focus manually, and when it is in auto focus mode; the zoom works fine. I disassembled the lens assembly: everything inside is free to move (zoom and focus lenses), the focus motor has the coils OK (not interrupted) and is not stuck (I can turn it with my fingers). I've read a solution posted on Dec 02, 2008 where it is suggested to change some weak electrolytic capacitors installed on VC-126 PCB, in my camcorder there is no such board, but there is VC-103 that contains the focus motor driver (IC855), I suppose it's the same board. Which electrolytic capacitors should be tested and/or replaced?
Thanks in advance! Stefano.
