Kortek Neo-Geo chassis, working after power supply looked at

[Lutus]

Hi guys, just picked this Neo-Geo machine up and the guy said "don't work"... the usual.



I smoke tested the thing and the monitor came up like the flyback was turned up too high, kinda white, so I knew the monitor would probably function.  The game board had no games but the test pattern stuff should come up.... didn't.  So I started dissassembly.



This machine was located in a beach hotel or something.  Power supply totally shot.  I rigged up an ATX computer supply to power the board and the thing WORKS!!!!

The monitor does need a cap kit but I cannot determine the chassis.  Here are some pics...







It is connected to a Zenith tube with the number G-A63ADG25X and 04RC0105-009.

So, anyone recognize this chassis? 

Or any insight into the "best" Neo-Geo games?

attaching pics for easier viewing

EDIT:  I know I need to invest in a compressed air can.

Don't know about the chassis, but there are some great fighters for Neo-Geo, IMHO.  Samurai Showdown IV, Garou, etc.  Metal Slug games can be fun as well.

Looks like a Kortek monitor made for Sharp Image. Something like a SI-325 model maybe.

I finally got the monitor out of the machine.  Some moron had locked his coin box closed with a bar and then lost the key to the padlock.  Thankfully I had a lockpick set handy, 10 seconds with a rake pick and it was all over.   

Removed the heavy monitor and can confirm that the chassis is a Kortek.  Will post a CLEAN picture tomorrow evening sometime.

Does anyone have any manuals of Kortek chassis that I can download since this one did not come in the cab?

Is there a common place on the PCB that will have the model stamped on it. Can't find one anywhere.

Kortek monitors generally have model numbers starting with "KT".

Hopefully these images will help us narrow it down some...

here is an exact chassis(mirror imaged) made by sharp image with some interesting comments in the answers link

Thats the one!   

I overlooked this thing at least twice due to the fact that the adjustments knobs are shown on the board on bobroberts website whereas mine are on an extension cable.

I will clean the board up, send bob roberts the pics for this chassis and try to get a cap kit and flyback.

Any other parts I should look at replacing while I am at it?


EDIT:  I double checked the IC's and they are the same number as bob mentioned in his write up.

if the picture is good i would not bother to do any work on the monitor,dunno why you want to change the flyback-caps yeah maybe if you have some concern over the age but the flyback i would leave unless its arcing

[Lutus]

Now that I have that honking monitor out I have to order a cap kit for my other monitor (flyback for arcing) I may as well replace the caps while it is out.

I also just touched up some suspect solder joints that looked like early cracking.  Someone (previous owner) has already done some solder touchup around the flyback looks like.

I am in contact with Bob Roberts currently about the cap kit possibility.

Eventually I will make a post in Project Announcements about this machine but was just getting excited and wanted to say that I had ordered a new CPO from Mamemarquees.

Still need to buy new joysticks and buttons as these have been abused. 

[Lutus]

Well, no cap kit so I put the monitor back in and now have two cartridges "Aero Fighters 2" and "Samurai Shodown".

After cleaning a couple layers of dirt and grim of the monitor and using my computer power supply to power the game board.... she is alive.

Will post pictures tomorrow, but for now I won't need a cap kit.  It is very workable.

[Lutus]

Alright,

Ordered a power supply and got a new CPO in from mamemarquees but haven't installed it yet because I am flattening it out.

Oh, yeah, those are also all new joysticks and buttons.
