Wells 25" issues with the Babystar multicade xxxx-1 boards

Hey everyone I see there was a old post about this but I'm having the same issues and don't see any solutions so I'm just curious if there is one definitive answer.

Just got done wiring up a Well 7191 25" that I know tested out and worked fine on a soul edge board and full re-cap. monitor displays but there's a curl on the top left that I can't get out. Is there a magic cure to this? Currently I'm running the board off a 400 watt ATX both the main board and the Jamma harness are tied into that one PS. I've tried to play with the video setting but nothing there.

Do I need two seperate supplies ?

Was there a switch or ground that needed to be played with.

Anyone ????
 
Try changing the value of resistor R43 on the 7191 from 2.2k to a lower resistance value. I did one troublesome 7191 and had to replace that resistor with a jumper wire. It made a big improvement. Did not completely eliminate the problem, but really helped.
 
OK got it Just had to change it to PAL and re-adjust the vert hold and damp. Works great with just the one 400w PS also with the jamma harness tied into the extra plug-ins. SO apparently the NTSC setting in the 7000 is off a bit. Hope this'll help someone else...
