Dear Kevin...there is likely a DC-DC converter , a shielded box a little
smaller than a pack of cigarettes, sandwiched between the transport and the
camera
section. it supplies the "C9v" (camera 9v) and possibly a C5v voltages.
inside of it, there will be several small capacitors (i think 4 of 'em) who
have become defective. you can use your ESR meter to tell which ones and
replace them with small radial capacitors. Personally, i prefer the VHS
camcorders
over the small ones, and once this is taken care of, the owner should get some
good use out of the camera.
Identifying the DC-DC converter is a little tough to someone who hasn't seen
one before...as i said, small metal box, behind the pickup's shield, in front
of the transport, single multi-conductor plug going to a PCB. there is
usually a metal "tape" over the seam's of the box's shield.
hope this helps
