Hello all-

Ive attached some pictures of this 19" monitor that I got in a lot. Can someone help identify it and the more important question... will it work in my pac man cab?

Ive also taken pictures of all of the wires coming from the monitor's chassis because I have no idea which wires do what. There are alot and also a household plug, which is really confusing. What am I dealing with here?

also that same sticker tells me that the Red wire is 'R', Green is 'G', and Blue is 'B'. Similarly, B/W wire is 'sync' and white is 'video'. Can I just connect those to the correct wires from the pac harness? What about the power cord plug from the monitor? Should I just cut that off and connect them to the correct ones from the brick?
 
Normally, the white wire is sync and the black (or darker colored) wire is ground. And yes, cut the end off the power cord and adapt it to mate with whatever style connector is hanging around in the cab...
 
now we are getting somewhere. Since I dont know pac's that well, can you direct me on what the wires from the pcb harness go to? I know where the red, white, yellow, and green wires connect to but what about the 3 orange wires going to a connector as well? can I just splice those all together and attach them to 'sync' coming from the monitor?

also, from the power brick of the pac I have the power wires carrying voltage to the monitor and there is also a yellow wire. What is the yellow wire for and where do I connect it?

You should have a black wire and a white wire coming off the isolation transformer which is the isolated AC for the monitor. A third wire (which is usually yellow and green in early Midway cabs) is the ground wire that you need to attach to the frame of the monitor somewhere (doesn't matter where, as long as it's metal on metal).

If you would take some pics of the wiring inside your cab, it would probably make things a lot easier...
 
i can do that! lol. Pics are attached as to where im at. Ive got the power to the monitor figured out, so now it looks like ive only got one thing left to figure out and that is sync.

in the pic, the bottom half, you can see the wires coming from the pcb in the cab. I know where the red, white and yellow wires connect to in the upper picture, but where do I connect the orange cables of the bottom picture to the top picture? The orange wires in the bottom are sync correct?

You know, all this information is in the manual...

But, for what it's worth, I already looked this up for someone else recently, so here it is:


Going to the monitor is going to be two small plugs - a 6 pin plug and a three pin plug. The six pin plug carries the RGB video and ground. The three pin plug carries sync.

According to the manual, the wire colors are as follows:
Red Video: Red/White striped
Green Video: White/Brown
Blue Video: Yellow/Blue
Ground: Green/Red
Sync: Orange/Red

thanks for that information. I actually saw that you posted that for someone else and it helped trememdously since I couldnt read the small print in the manual for crap.

Ive since connected the RGB wires, and also the sync and video wires to where I believe they should go. All I get on the screen is a nice bright vertical line down the center of the monitor. ? No sounds or anything. I need some help figuring out where to go and I STILL have no idea where this monitor came from or what it is.
 
A bright vertical line down the center - which way? When talking about monitor orientations, we always refer to the monitor as if it were horizontal, oriented like a television set. With that in mind, is it a horizontal line or a vertical line? Can you hear the game playing if you coin it up?

Also, how did you hook up that "video" wire? I believe that the notation (video in parens) means that's the video ground. What did you hook it up to? Also remember that the video ground from the game harness should not be connected to AC ground - it needs to be connected to the video ground from the monitor.

-Ian
 
the monitor is mounted vertically so the line is a vertical line. heres a pic. Also, the other picture is how I have the monitor connected to the pcb with labels of what the wires are from the monitor. Is this not connected correctly?

seems to me that harness is hacked to bits maybe you should get a new one from bob roberts?
 
That looks to be connected wrong. From the looks of things in your pics, I would connect the green wire on the pac harness to whatever is labelled as the video ground coming off that monitor (maybe the white wire?) and I'd connect the blue & white wire from the monitor to the orange & red sync cable(s) of the pac harness.

One question (since I don't have a pac manual handy) but what type of sync does a pac boardset put out? You may have to play around with the two orange wires to get it to sync right (are they tied together at the molex or are there two separate sync cables coming off the pac harness?) ...BUT!!!... it you can't get the board to play blind to begin with then this whole operation is going to be moot anyway; you generally want to have a known working boardset handy when you're troubleshooting a monitor...
