Need schematic for Samsung SFA-410ED camera

[jmelson]

Hello,

I am repairing a Quad/Samsung QSA-30A P&P machine, and the downward vision camera had developed a problem.  Apparently it is supposed to lock to an external sync source, but it stopped syncing.  I can see an image rolling horizontally on the vision screen.

I traced the external sync back into the camera, it goes to a trace and then a via on a 4-layer board at the back of the camera, and then doesn't come out anywhere.  I'm guessing a trace or via has gone open on the rear connector board.  This looks like it could be a really easy fix if I only knew where that trace was supposed to go.  but, the connector board is soldered to 3 multi-pin connectors, so it is hard to examine the underside of the board.  Some secret stash of schematics would make this an easy fix.

This is a 20 year old camera, and I have had no luck finding any info.  There are some units for sale on eBay, but no manuals or other docs.

Thanks,

Jon
