is it just me or does everyone have frame ground issues when building new games?
ok when i make up new cabinets, or used cabinets and sometimes use old school rgb low res monitors, or sometimes lcd's, and different makes and models of power supplys i almost always have issues with frame ground and have to experiment to see what the game likes lol. why is that? you would think it should be universal, a frame ground is a frame ground and should not matter what brand of monitor power supply ect?
but it does!
today making up a multi game i used frame ground on the lcd and power supply, and on cabinet wiring only to have it fry the ground wire coming from the jamma pcb to power!
remove the frame ground from the lcd, and then its ok !
other times i have had frame ground connected and it causes game and or power to reset?
removed it and its ok!
other times i have needed it connected to get rid of trace dots floating in happ monitors ?
and then again sometimes it needs to be disconnected to get rid of those?
any tech gurus have all the answers for frame ground?
