Help with Star Wars Trilogy Arcade (Sega Model 3)

[LimeiBook86]

Update Got the game running! But now I need help with the monitor, please see below. Thanks!

Hello everyone,

This is my first jump into the world of arcades, so please forgive me for asking newbie questions or not knowing the correct terminology. I would appreciate any assistance possible.

I recently purchased a Star Wars Trilogy Arcade off eBay, this weekend I drove to pick it up and I finally have it in it's temporary home of my room. Now the machine works says the seller (and I have photos of it up and running too), but it's beat up, the wood panels have cracks and it's in a bit rough shape (The machine fell down while in transport before I bought it). So needless to say it isn't the prettiest arcade -- but it works!

Only issues I know of is that the display isn't perfect, besides the usual burn-in I saw some of the colors were "off" or not showing up, but that's not the issue I need help with today...

My problem:

When I went to pick the machine up the guy had basically everything disconnected or unplugged. The Model 3 Game board itself was not disconnected thankfully. Now I have the manual, but I'm still hesitant of course, I don't want to fry this thing and it doesn't show many wiring diagrams.

I have the power supply and large power board (sorry I don't know what else to call this - it's a large board with what looks to me like power supply related elements) attached with most of the cables, but there are a few lose cables and I think one fuse is missing from the large power board. I don't want to plug it in or turn it on until I am sure everything is connected correctly. The last thing I want to do is break the poor machine I just lugged home over 200 miles.

So I'm wondering if anyone here may be able to assist me. I guess what I'm looking for is any wiring diagrams or photos. I'll be happy to take photos tonight of my setup and what is plugged into where.

I would appreciate any help on this subject as I'm eager to power this thing on and give it a go.

Thank you!

This should have a lot of information you need: http://www.sauservice.com/manuals/STW_html/stwmain.html . What cabinet do you have (upright, deluxe bench, or deluxe)?

In most cases, the majority of wires will only connect to one place, so you're pretty safe to just start plugging. I'd also do a sanity check when plugging in that both sides of the connectors have same color wires on each side (rarely do they change wire colors across connectors). The connectors are usually the same color as well.

Thank you so much for the information! I have the standard upright cabinet, forgot to mention that earlier! I actually plugged everything in and got it working. Made a little YouTube video too, as you can see some colors are a bit off. The subwoofer speaker cable colors were different, but it's the only connection that fits so I'll have to plug that in later. Now onto the monitor, but I'll post about that a bit later.

I'll take some photos to aid others in the rare event they may be useful.

Cool... congrats. The monitor looks pretty good in that video... the only thing I can maybe see is some discoloration, which most likely just needs a good manual degaussing. I'd go into test mode and do some of the monitor tests, and post some still pictures from that if you still need help.

Thanks! Yeah I think I need to degauss the screen. I may get a proper wand or ring online. Any recommendations?

I went to show the CRT test and the color pattern only shows toward the center, and it looks fine - however the colors are distorted towards the edges of the screen. The grid / alignment test was pretty good. Only slight banding / curving at the very edge of the screen. I'll post photos soon.

I really appreciate the help and advice, thanks!

I have a big degaussing coil, sorta like: http://cgi.ebay.com/Degaussing-Coil-...item2a0d413c57 , and it works well. I don't think the wands work as well, and I have a small coil, which doesn't work very well on larger monitors.

If you have a AC powered plug-in drill (not battery powered), you could try running that near the monitor for a quick/cheap attempt (just don't hit the screen with the drill!). The motor causes a magnetic field similar to a degaussing coil. I've heard some say they've had luck using actual magnets as well... either waving them around by hand, or attaching them to a drill so it's constantly moving. Just be careful not to use too powerful of a magnet too close to the tube.

The other possibility is that the rings on the tube neck have moved. Those are kinda a pain to get adjusted properly, so I'd definitely try the degaussing coil first. If you need to adjust them, be sure to mark their current position first, and check for previous markings (if there are previous markings, try them first).
