I am trying to use a WG 25K5515 with a jamma harness, video set up like:

1 - R
2 - G
3 - B
4 - Gnd
5 - Blank

1 - Blank
2 - Blank
3 - Jamma Sync

I am getting what looks like a "roll under" on the righ side of the screen, but otherwise the monitor looks perfect.

I thought I remembered read a post about K7000's having an issue with certain jamma boards and how to fix it, but my search-fu is lacking. I am not even sure if it is relevant, but the monitor looked just fine when it was in the Leland Quarterback cabinet.

Thanks in advance...
 
What you are thinking of (I think) was the 25K71XX's
 
i thought there was an issue with GO7's and the input signal from the 48 in 1's causing a curl. thought the K7000's were good. i think your sunc input is wrong.

You are probably right, I have gone through a ton of 7197 and 7191 chassis.

According to the diagram on the chassis, I have the jamma sync attached to -(neg) horizontal sync.

I also tried jumping (attaching it to both wires) the jamma sync wire to -(neg)vert sync and the issue is still there.
 
The 5515 is a medium resolution monitor, are you using a medium rez board? This monitor can't be switched to standard resolution either
 
Ok so two corrections on this one -

First I was referring to a K5501 (std res) not 5515 (med res) - my fault

Second, after looking for the pictures of chassis online I know see that someone left behind a 5501 tag on my frame but the chassis is actually a 7100 (K7107)

Which would explain the problem.....
 
That being said, what was the solution to the 7100 problem (this is a 60 in 1 board)
 
I just spent 30 minutes googling the solution to the k7100 prob, but no luck
