Almost done! Monitor plug in HELP!

Spike Spiegel · Nov 11, 2005

Plug and play? HAH! I had to change the metal brackets in order to hold the monitor in, and then the plugs I unplugged from the last monitor aren't on here. Will have to splice it up? Anyone, help! Got pics... can someone help me, I'd like to try this monitor out tonight. Thanks,

Like I said in your preveious post, some monitors come with different size video plugs. If your new monitor didn't come with a plug, you'll have to find one somewhere. If it did have a plug, just splice into your harness. Match the colors.

how do I find a diagram of what's what for power, color and vert hold on my old one? I have one spot that's ac and ground, and another for blue, green, red, blah blah blah.

Spike Spiegel · Nov 11, 2005

Okay, I have a plug from the last one for the monitor and all... now all I need is juice, but (believe it or not) I don't know what plug that is. It's different. It's got two wires, and my plug in shows three. Is it the bottom picture showing a red and blue wire? That was connected to the monitor with a tag "isolation transformer MUST be used". Is that the juice? If so, which is which? I'm so close to being done!

NEgO MANIAC · Nov 11, 2005

In your first picture, you see a set of prongs on the board. That's your video input. Your power is just two wires. They are usually black and white and are a much thicker gauge wire. Ground is green and screws onto the metal chassis.

Spike Spiegel · Nov 11, 2005

Yeah, I've got that taken care of. I know the ground, too. So, what about the mystery red and blue wires from the first? That's GOT to be power. What else could it be? But, the question is, which is AC hot and which is AC neutral? Man, this sucks. So close, but so far away.

Spike Spiegel · Nov 11, 2005

I see! The power is going into this "isolation transformer" thing. That's where the blue and red come from... and also the green is there, too. Could I use the power that comes out of that into the board? What color is what, usually? Furthermore, if I use the wrong color, can putting hot into the "not hot" and vice versa kill my monitor? My BRAND new monitor?

Spike Spiegel · Nov 11, 2005

Now all I get is a purple screen. Bright purple. So it has power. I wonder what's missing? I know that the red, green, blue are all hooked up fine, as I have the manual for that. What could be wrong, here?

Spike Spiegel · Nov 11, 2005

Nevermind, I got it running. It was my Jamma that wasn't in all the way. So what I learned was it doesn't matter that it comes from the transformer, and either side works fine for power (as I thought, since you can plug a plug in either way into the wall and it works, so....)

Sorry for all the posts. It looks amazing for a low res monitor. I can't wait for Vampire Savior to get here. Thanks to those that looked and Nego Maniac for some help :cool:

NEgO MANIAC · Nov 11, 2005

Just for future reference: AC doesn't matter which side you connect with. Both side are hot and the current alternates back and forth. With DC it does matter since current flows one way. Monitors are AC. Enjoy your new monitor. If you ever have to do it again, it will be much easier.

Spike Spiegel · Nov 11, 2005

Changing out the entire metal frame upset me, and when THAT was done, having to figure out the plugs sucked, too. But my god, the pic quality. All but one other of my arcade machines, while in good condition, do have old monitors. One has a cap kit done about 7 months ago, but this blows them away. The quality is almost too good on it. I see every pixel and every color.

For anyone that does a search function in the future, I hope this helps. Again, the red and blue wires coming from a transformer for a monitor still work as normal. Just hook them right up. Changing the chasis is sometimes needed, but not too much work. Overall, this with a new kit, new speakers, new monitor and new buttons and joystick will make the whole machine pretty much good as day one. I can't wait for my kit to come in the mail (tomorrow?)!

Take a picture of it running Spike

It wont do it justice, but i think you should anyway

After it's complete. I want to change the buttons and put Vampire Savior in it first, and I will do a final pic. Thanks again to everyone that helped and read! May this answer SOME questions in a search function years from now?

Now all I get is a purple screen

Sweet..Great News!!
I was going to mention to make sure the jamma harness was on..or on right to get a picture...make sure a board is plugged in..
But I'm so unknowledgeable when it comes to monitors that I try to stay out of the topic and let people who do know about them..help.

Reznor007 · Nov 12, 2005

The isolation transformer is used to separate the monitor from the same power going to your PCB's power supply. The incoming AC from the main power cord for the cabinet comes inside, usually goes through the main power switch, then splits, with 1 way going to the power supply and maybe the marquee light, and the other side going to the iso transformer. The power for the monitor should come from the other side of the iso transformer. It's the same voltage on either side, but make sure it's on the side that doesn't go back to the power switch or else you are bypassing it and losing its safety. It's purpose is to electrically isolate the monitor from your PCB so that a problem in the monitor won't fry the game board(rare, but possible).

This is why you buy monitors with iso transformers built in (or not required). :emb:
