I have lots of monitor parts and have no clue what can go with what

Basically, a friend of mine moved to a house that had an arcade/drive in at the back. In the barn was a pile of parts, some vids, lotsa pin stuff.

Out of the vid stuff, there is 2 working vids and 4 other non working vids.

Out of the non working vids, two are cocktails and one's a Neo Geo one slot.

One cocktial, the game plays but the monitor doesnt work, same with the Neo Geo and the other cocktail has no life yet. These are generic cocktails.

I have tons of working power supplies, 7 different monitors, about a dozen monitor power supplies and yokes, etc. I have no clue what can go with what!

The one (monitor power supply board)that was in the Neo Geo is the same as a couple of the spares I have. Others are smaller looking, others have slightly different input configurations.

So far, all I've done is hook one up after another to the Neo Geo (I chose that one because my friend swore he saw it working before so I'm hoping its the board and not the monitor or I'm wasting my time) but no luck. I wait a day and yank it out and try another one and so on. Also I tried hooking up a monitor to the one cocktail that plays but I'm in over my head.

You'll probably want specific model numbers etc but for now my questions simply are,

Are certain monitors interchangable?

Are some monitor power supply boards interchangable? Or is is like...you can only run a 19 inch monitor with a specific size, or power, monitor board? As in, you cant run a 19 inch monitor with the monitor power supply from a counter top that ran a 13 inch monitor...

In the meantime I'll try and compile a list of the monitors and monitor boards I have and maybe you can help me match up what can go with what.

Thank you

Where are you located?
Also,
If you come across a Wells Gardner K4600 monitor chassis let me know.
As for your monitor question, you will need to include actual specific monitor model numbers.
Try posting that question over in the monitor repair section you may get more info there.
 
yes, I'll try and get up to speed with this forum, where to post and other details. I'm new here but I'll catch on quickly. So I dont mind being steered in the right direction, all help is appreciated for sure.

So, I'll take some shots as soon as I can wrangle the camera back.

Ok, so these are called chasis I think...I was calling them monitor power supply boards) from trying to get some info from the side of one of these things. G07CB0 for example

There are three basic parameters you need to consider to determine if a monitor is interchangeable with another; color, graphic type, and resolution.

1. Color – There are three main types of classifications; black and white, color, and inverted color. Black and white monitors were typically used for games before 1980. (Note: some B&W games used color overlays which were basically sheets of multicolored plastic to give the monitor the illusion of additional colors.) Color monitors were used on most games made after 1980 and are by far the most common. Inverted color monitors, the most common of these being the Sanyo 20EZ, were used primarily on Nintendo games. Inverted color monitors used a CMY signal compared to the RGB standard of most other games. There are ways to make these all interchangeable but it should only be considered as a last resort.

2. Graphic Type – There are two divisions of graphic type, vector and raster. Vector graphics were found in games between 1977 and 1983. Raster graphics are much more common and were used from Computer Space onward. The two formats are incompatible without the use of a special adaptor.

3. Resolution – Most games and monitors you will come across are what has been termed "standard resolution." There are some games that output video at higher resolutions and I think this page should provide a good idea of some of the key differences: http://www.klov.com/monitor.html . Some newer monitors (and game PCBs) offer the ability to display standard or high resolution video signals but for the most part you will have to use the same monitor type as required by the game PCB.

There are a few uncommon issues worth mentioning also. Power – just about all monitors run on 120v and all can - most should - operate with an isolation transformer. One of the few monitors that does not run on 120v is the Sanyo 20EZ which should be operated with the 100v found in the Nintendo cabinets. Several newer monitors do not need isolation transformers but should not be hurt if an isolation transformer is used. Sync – most monitors can handle positive sync, negative sync, and composite sync with simple adjustments on the video signal wire harness so it is mostly a non-issue.

Most games and monitors are standard resolution color raster so generally swapping monitors is fine.

It's a much different story for swapping the chassis. You should be ok swapping a chassis for one of the same manufacturer and model provided it is for the same size monitor (i.e. one 19" G07CBO for another 19" G07CBO). Beyond that, it is more complicated. The size of the neck (narrow part) of the tube is an issue so it can be plugged into the CRT socket on the neck board. The actual tube size (13" 19" 25") is critical. The yoke impedances (horizontal and vertical) and chassis also have to match. Of course there are matches out there but as far as I know there is not a comprehensive list anywhere. You can search "tube swap" if you want more info on how to do this and what to watch for.

For identifying unmarked chassis, visit Bob Robert's site first.

Monitors in question pictures...just to follow up, will post in monitor section

Heres those monitors, I have a few more pics, if thats ok. In looking at them, 3 of them go with the G07CB0 chassis, which I have 3 or 4 or those...all probably need work.
And then theres other chasis's I have no idea, so I will post those too but in the other section
