Hey Gents,
Trying to get assistance if possible. purchased a broken atomiswave where PIN 14 (Video GND) on the jamma edge burned out. So it gets audio but no video. I figured for the price doesn't hurt to try to mess around see if I can get it up and running now I'm not the greatest when it comes to soldering or terminology on parts and such so please forgive me. But what I tried to do was recreate the edge connection with copper double sided tape and I get continuity when I check the ground. following the path of the burnt destruction I saw a broken trace where the FL7 is on the board. So i bridged a wire from the trace to (filter?) and also i noticed the other FL's had continuity when you checked both sides so i had to run another wire from the trace to the other side of the FL7. Also it looks like the ZD14 (68N) blew and from what i found online removing it should allow you to test since it is just there to prevent over voltage or something. anyway doing all this no luck not sure where else to look or what i should try to do. i have two jamma connectors a cbox one and a neo jamma with the R, G, B , S wired to a cga/ega/yuv to vga converter. I also tried through the vdo port with a vga cable to my tv as well as through the cga to vga since that as a vga in port as well.
its a bit lengthy sorry guys any direction or guidance would be appreciated a schematic even though i can barely understand them would be good too.
