David,
I have a schematic for HRS3900, not sure if it is close.
This shows CN1 on the AC head and main board.
I'll see if I can email you just this part as the whole thing is too large.

Load, drum, capstan, all work. As I said in my previous post, this VCR
functions (but with no display) when connector CN1 is disconnected from
power supply board. What I need is information on this connector, where does
it go? It looks like over to RF modulator, but I'm not sure. What ever this
connector is feeding is the problem. Could someone with a schematic please
confirm this. Thanks in advance.
