Gonbes 8200 help

[kinooshi823]

I was referred to this forum by a friend and I was hoping to find some help.

I've been working on a project for over a month..converting an arcade1up to a jamma cab. After many trials and errors, I feel I am close to completion. I want this cab to specifically play Mortal Kombat 3 as I have the board. For the past week, I had an issue where the video would freeze due to the monitor not playing 53hz which I found a solution to today. Now here is the other I am having...The picture is dim. I adjust many settings on the gonbes and on the lcd converter connected to the BOE monitor of my arcade1up and I have had no luck. There was a monitor I wanted to buy at academodup, but I don't want to risk spending extra money on something that may or may not solve my issue. I was hoping to fix this issue with what I have now, and budget wise, I have spent a lot so far on this project. Would anyone be able to give me some kind of advice to fix this issue? I would like to specifiy this only happens when I use the older Mortal Kombat boards that support 53hz. Other boards I have and a neo geo mv1b work fine at default. The Tekken boards though, the colors look a little too bright and washed out, but I wanted to tackle the mortal kombat issue first if anyone can give me some advice.

Maybe try this project if your board can be used.

The cfw project is intended for use with consoles.

@kinooshi823 have you adjusted the color pots? I don't see that specifically mentioned above.
