K7000 / NBA Jam TE monitor bouncing

[fabes23]

I just picked up a k7000 monitor for my NBA Jam TE and I'm seeing this on the screen (See links). It's all shaky and doesn't focus. I am thinking it's the sink connections, but I'm not 100% sure. Is there anything I should check? Anyone got an NBA Jam that can share pics of the sync connections?

Thanks for the help in advance!!

Sync wire to the last pin only. Then adjust your vertical hold.

"Last pin", like furthest away from "red"?

Yes

 

[fabes23]

Did that. No change. What the heck?

 

[gutz]

Did you adjust the vertical hold/sync pot? Is the pot broken?

I rewatched the first video - you don't have a k7000 monitor. Its likely one of the u2000/k7400 varieties. The signal connection is still the same though. Red-green-blue-ground-empty-empty-pin-empty-empty-sync.

heh, probably K7400. I think it's cute when people think those are "K7000s"

also why do you have a JAMMA game with 2 separate sets of sync wires to the plug? that's not even technically possible. follow whichever wire goes to the Sync pin at the JAMMA harness... that only goes to pin 10 of the signal header.

Fixed the wiring. But, Same problem.

Red, Green, blue. then nothing. First nothing should have a black wire for the ground. Can't believe nobody caught that.

Red, Green, Blue, and The "ground" on the jamma harness is a white wire with a black stripe on it. That wire is currently in the "ground" position on the chassis next to "blue." Look at the video and pause it at :34 seconds.

Bad vertical deflection IC?

Bad vertical deflection IC?

seriously dude? it's obviously wired wrong.

I got it. Bad remote. Swapped remote. Working.
