If it's that old it's probably worth trying to fix even if it's a complex electronic issue, but a service manual with schematic is going to be critical to success.
I do have a couple of Service Manuals for this VCR, but they are Sam's Photofacts that I downloaded from their website, so the schematics and what not are cut up into pieces.
Could a bad capacitor in the control board cause these issues? I know this unit uses the old Matsushita caps that were notorious for failing over time (the purple ones.)

So what part of the service manual would I look under to find that circuit, so I can start troubleshoot it?
Is there a specific name for that portion of the VCR Circuit? I'm asking because the Service Manuals I have go by the names of what Panasonic put on each of the boards (ie Servo Board, etc.)
