How to reverse a mirror-imaged monitor?

[nocashvalue]

K. So I took the monitor out of a gutted Exidy shooter cab (which uses a mirror) and put that badboy in a POW Jamma cab. The image is still displaying everything backwards and upside down.

What do I need to do to correct the display? Is it a rewire of the yoke cables? Although I don't have the exact model number handy, this is a WG monitor.

Four wires come off the yoke to the board in a single connector: Red/Blue/Green/Yellow. if it is still intact, you will have to cut between the two groups (Red/Blue[]Green/Yellow) and flip the pairs. Be careful here! what I mean is flip Red/Blue to Blue/Red, and the same thing with the other two. DO NOT SWAP THE POSITIONS OF THE PAIRS!! Actually, most monitors I've do this to have a different spacing of the pins, so you can't swap the pairs....

Some monitors have connectors on the yoke itself that just pop off and can be flipped. I don't recall which ones do.

Thanks raven. I figured that's what it was. I'll have to be really careful. I accidentally did this to a G07 the other day and fried something.

On the G07, the wires you flip aren't adjacent, so if you swap adjacent wires like you do on the WG's, you'll burn something up. On the G07, you swap the red and white, and swap the brown and gray.

Although, someone told me that if you just swap the A/C input wires on the monitor power connector, it'll change the ploarity of the A/C and reverse the image both ways. Haven't tried it to see....

Reversing the AC polarity definitely doesn't work. I did hook up the yoke wires on a G07 wrong once and the monitor displayed vertically on a horizontal monitor... although luckily I noticed it wasn't right after a couple seconds and turned it off before frying something.
