Area 51/Maximum Force combo - Faint diagonal scan lines

My area 51/ maximum force combo (in a dedicated area 51 cabinet) is displaying faint diagonal scan lines that are driving me nuts trying to fix. I backed the cab up to another cab and hooked the area 51 combo board to the other cab's monitor and it still displayed the lines. I hooked the other cab's pcb up to the area 51 cab's monitor and that game looked fine. So the monitor in the area 51 cab is not the problem. Is there anything on the area 51 combo board that could be causing these problems or is it some kind of cabinet wiring problem?
 
hmm... that sounds like an odd one. Id love to see a pic of the issue. also are you running the dual board setup or the single board setup? have you checked your +5??

do these lines stay stationary or do they move around going faster and slower? if they move around faster and slower, might be "noise" from a old krappy power supply.

This is the dual board setup. I believe it is the board that came in an Area 51/Maximum Force Combo conversion kit. The board came out of a generic cab I bought. I put the board in a Dedicated Area 51 cab.

I will look at the power supply and try swapping another known good power supply into it.
 
thats an odd one... do the guns still work properly despite the lines? do the lines move around or are they always in one spot? If theyre moving around that reminds me of power supply noise.

ive heard of(but not verified) stories of monitors whos (earth) ground wire was the issue... some, removing the ground wire fixed it, Others adding one fixed it. others, tying the power supply earth ground to the monitor fixed it, etc etc etc etc



ALso make sure the game is properly grounded, seen the ground prong broke off many times...

if you cant make much headway with it but guns work fine, personally if leave it.

alternately, if you have another jamma cab just plug in ther board watch attract mode, see if the scan lines follow the pcb itself.
