Think I've fried a SEGA Model 1 Virtua Fighter
daplino:
Pretty active forum!!
Really Nice to see so much people trying to help out.
I understand your point of view, I also thought at first it wasn't worth to get it repaired but... let me explain my point of view.
when I first found the virtua Cab I wasn't expecting much of it, it was a cheap way to get introduced to arcade games and electronics in general.
There where so many Board, cables, components,etc... I thought I would never be able to get it work at all.
Today I fell like It would have been not so fun in long term to get everything working at once.
So when I "fixed" the PSU problem (just bought one and wired it properly, at least the first time ::)), after documenting and understanding how every component was interrelated from the Power suplly point (hope it's clear enough), after that I felt like I had learned something. I will never see any electronic stuff the same way. I feel really good about learning, it's worth a hundred "Lindberg" cabinets (for example).
Now maybe I will in fact not be able to repair it but I'll try, I've read lot since yesterday on Randy Fromm site. I feel nearly able to test the components on the boards I've fried.
You guys go on giving people hope in what they're doing...
BTW I have another problem, even if I want to get another board or to Mame my cab (shurely I will) : the monitor don't seem to turn ON, I'll have to check it also.
I'll do it when I will get more confident in what I'm doing, cause I could fry much more than a plastic board.
I won't hesitate to post questions when I get some more precise than "what if I have no image with my Nanao MS8-26SU"
Thanks all you're great

Seriously, I got into this hobby because I wanted to build a cab. A year later I haven't built one but I have learned so much that I don't want to build one, I want to keep getting old machines and bringing them back to life instead. This hobby is a tremendous learning tool in so many directions, from carpentry, to electrical engineering, to art, to software engineering.

A monitor can be dead due to a number of reasons, the simplest being a blown fuse somewhere (on the fuse block in the cab, or on the monitor board itself) ranging up to more difficult problems like a blown flyback or a cracked crt (cathode ray tube). You should definitely read up on monitor repair a LOT before you start tinkering around with it. A monitor can store a large amount of charge, and this charge can be lethal. Here is a good place to start, if you have not already:

If you are observing safe practices, monitors can be rather straightforward to repair. Most arcade monitors use single sided circuit boards, and repair/get well kits are availalbe from several reputable vendors. There are also some nice troubleshooting flowcharts available online.
Good luck,

There is a row of about 5 red and 5 green LED's on the main CPU board. When power is there and correct one of each color should light up. Then, if the game starts working, the other 4 of each color will flash quickly.
You might have damaged the boards, but I don't know about repairing them. I do have tested working spares I can sell you if it comes to that. You can email me directly at wadelanham @ hotmail.com.
Good luck! Be careful with those voltages next time. :)
