Title: WG4901 with issues! Post by: iankellogg on March 06, 2014, 09:39:58 am I have had a WG4901 that has had various issues that i have been working on. It had some sync issues before so I figured I would do a capkit to help it along. The cap kit worked mostly, it cleared up the red tint and jail bars as well as some alignment issues. However now my sync is really messed up.
After messing around with it this is the best I could get it http://www.youtube.com/watch?v=UBrohl1XKVM I'm really not sure which sync is having issues, i really don't know much about these monitors yet.

Title: Re: WG4901 with issues! Post by: iankellogg on March 06, 2014, 11:16:48 pm well it turns out that the hsync+vsync jumper was the problem. I got the cab with the jumper in place and even ran mame on it with no issues. As soon as i did the cab kit i had all kinds of problems until i followed that flow diagram and removed the jumper. all is well now, just need to get a hold of a jungle king board and bezel and the game will be at a solid C- .
