These games usually have plenty of documentation, With enough research you can fix it. Just don't do anything your not absolutely sure about.

Fixed it! called in my friend who repairs arcades. finally gritted my teeth and did it. i read the Yolk Flipping guide by Bob Roberts: http://arcadecontrols.com/BBBB/yoke.html I did it a bit differently instead of switching the wires down below, i switched them at the top where they go into the monitor itself as suggested by my friend. it was too difficult to change the wiring down below because the wires went directly into the circuit board. we were able to measure the pair of wires with a multimeter/voltmeter. there was a higher voltage for one pair and a lower for the other pair of wires that needed to be switched, so it was easy to know how to not cross them and damage the display. if the wrong wires are measured with the multimeter then you will not have a closed circuit so you will not have a reading and you will know not to cross those wires. pretty simple. |
