Are sync issues common with Bump n Jump? I haven't gotten mine figured out, and I was just watching the upstairs awesome arcade video in the general vg forum and his bump n jump was not syncing either.

Basically the v hold won't sync. You can get it perfect for a minute or two if you're lucky, but eventually it will start rolling again.

I'm assuming at this point it is a board issue and not the monitor, as I have tried a few.
 
If anyone has this issue its likely the connection at the pcb,either the connector isnt pushed on tight or the the connection is dirty for the video gnd. My b n j did same thing last night , wouldnt sync 2 different monitors.
 
did you ever figure this out

Glad this thread got bumped, I never replied with the solution.

It ended up being super easy. One of the sync wires going to the monitor had never been connected. It was snipped at the homemade-looking wire coming from the PCB or harness. Jrok saw it, tested it, then crimped a socket to the wire, attached to monitor chassis, and voila!

I think BnJ needs both a positive and negative sync. But that's my memory, which is horrible.
