I´m a spanish guy who just bought an arcade machine with the monitor not working. I will try to fix it, but I have to identify it first...
The Cabinet is a Virtua Fighter 2. The chasis is very similar to a "MS9-29A-T-SU" (http://www.jomac.net.au/Nanao%20MS9-29A-T-SU.JPG"). The monitor must be a nanao, but it hansn´t the "Nanao" name on it. The only sticker is a number "M68JUA068X". I have read that 68 means 68 cm, and my monitor could be of 26-27 inches, and not 29 inches.
Is it possible?? Can I have a "MS9-29A-T-SU" chassis and a 27 inches monitor???
Monitors have two parts, tube and chassis. I'm guessing you want to know both.
As stated before make sure that your stuff is clean, then it gives everyone a fighting chance at ID.
I have found a number in the Chasis: 05a00585D1. And in this page appears this: "Nanao 05A00585D1 110V~ 25kHz Monitor = MS9-29SU aus Daytona Twin" (http://www.medi-gmbh.com/reparaturen2l.html")
