Hi I just bought final fight arcade
the sound and game and controls work great, but the picture is terrible
heres a pic
does it need a new monitor or caps kit? i know nothing about arcade machines, have been doing research though, i heard caps kit can be tough to install, i just want to know with my loss of experience if the machine needs a monitor or a caps kit

Looks like the adhustments are all off especially H. Hold. A cap kit would probably help and is usually the first thing you want to do if the adjustments don't work. Also make sure there isn't a remote board that is disconnected or loose. A cap kit is not that difficult if you have rudimentary soldering skills. It just takes time.

Either way get this one repaired because replacement monitors are hard to come by and expensive when you find them now. CRTs are becoming a thing of the past... And LCDs suck in an arcade game (that wasn't designed for it).

Thanks for the comment and your help, could you be a bit more specific with adjustments, is it a dial or some kind of jumper to adjust on one of the boards, and the remote board that you are referring to, could you tell me what major component its connected to or perhaps a pic, sorry to sound so ignorant, i would just take it to the professionals, unfortunately in memphis no one works on them.
 
I was refering to the adjustment pots on the monitor chassis. A remote board is just a small pcb with monitor adjustments that is attached to the monitor. Usually mounted in the control panel so you don't have to open the back of the game up to tweak the settings. There should be an adjustment pot thats says H. Hold or frequency (horizontal hold). You should be able to get a stable picture by turning it a bit.
 
An arcade monitor adjusts much like a television. Horizontal and vertical hold controls, etc. All monitors have them, but they may be in different places. Either on the monitor chassis (main circuit board of the monitor), or on a remote adjustment board. Before you go turning knobs, tell us what monitor you have. Should be on a sticker on the frame of the monitor (not on the bell of the picture tube). Probably a manufacturer like Wells Gardner. If you can't figure out what monitor you have, take a picture of it from the back, make sure we can see the monitor's electronics.

I can tell you right off the bat its a hitachi, im not at the house now, i will post detailed pics, when i get there, thanks again for everyones help in the matter.
 
found the h hold and v hold knobs and turned them, still no difference i did take a couple of pics of somethin on the monitor board that i noticed here they are, the big black capacitor or whatever it is, may have caused this leak whatever substance that is, so would it be safe to say i would need a cap kit?
and if so where would i purchase one?

Just to add some more info, theres a sticker on side of monitor that says
hitachi type 510NJB22, if i wanted to just replace the monitor would any brand monitor fix this? or would i need to find a caps kit for it?

That would be the picture tube. We need to find out what kind of monitor you have. I can't tell from that little corner of the chassis.

The hold controls have no affect at all? Perhaps the sync wire came off it's connector. Look at the input connector - it should be a cable with five or six pins that plugs into the monitor and leads to the wiring in the game. Make sure none of the wires have broken or come off.

If you can, take a picture of the entire back of the monitor, so we can see the electronics. That'll help identify what kind of monitor you have.

Also, I really can't tell what that is that's leaking from that photo, it's too small and fuzzy. I can look again when I get home - my monitor here at work is so worn out that it shows up very dark - I tried brightning it up in a graphics program, but I still can't tell what's leaking.

I turned the hold controls, but the image as in my original pic at the begining of this post stayed the same, it only adjusted the vertical horizontal view of it. I will definitely look for that connector when i get home, here is a pic of the back of the machine, i dont know if its clear enough for you though, or if i should remove the monitor board, i can make a better pic, just let me know, and thanks for you help,

Hi I came home and i believe i found the "input connector" im posting a pic of it, its the grey vertical plug in the pic on the left, it looked like it was plugged and fine, i also took another pic of the back of the monitor, please let me know any way you can help, thanks!!

Does anyone know what kind of monitor i have from checking out my pics?
 
It looks identical to the Toei CM-A20, so i should purchase a caps kit? The issue, did'nt look like a problem with picture tube? After discharging the monitor, do i just unplug everything, keep a record of everything unplugged and record where it goes? since this is my first cap repair.
 
A problem with the picture tube will result in a dim, washed out, or badly colored picture. It won't affect picture size, shape or sync. Your problem is very clearly a chassis problem/wiring problem.

Replacing the capacitors is almost always a really good idea - but if you've never done it before, I would suggest practicing soldering first. To remove the chassis, yes, just discharge the monitor, disconnect the anode lead (big one with suction cup), disconnect the deflection yoke and degaussing coil from the chassis, pull the neck board off the back of the picture tube, and disconnect the input connector. Remove the screws/clips that hold the chassis into the monitor and slide it out.

Investigating whatever has leaked would also be a good idea. Try to get a *good* picture of the area in question, and whatever appears to have produced that goo, so we can point you in the right direction for repair.

Where are you from? Maybe someone close by could come by and help you with this.

For the first time you sound like you might be over your head. You could hurt your self or mess up the machine really badly if you did a mistake.
 
I know im opening a whole new can of worms with this question, but i was told by a co worker i could put a crt computer monitor in cab to fix the whole issue, is this possible and if so, where does the pcb connect to? is their some kind of adapter? and if so since computer monitor uses and ac power cable to power it on, does the power supply in the machine, some how keeps it powered on? thanks for any help on this matter!

No, you cannot do this. Computer monitors are intended for VGA resolution, and sync to a minumum 31.5khz. Arcade monitors (standard resolution) is 15.75khz. Off by a factor of two.

Yes, they both take an RGB video signal, and yes they both run on AC power. But interface-wise, they're very different.

Now, some very recent games actually do use VGA resolution monitors - but the monitor you have, is not :)

If you think you're in over your head, you can always let us know where you are - maybe a member could come and give you a hand. Or, if you want, you can probably send your chassis to Chad at ArcadeCup - he might work on Toei monitors.

I totally aggree, Im in Memphis, I could not find anyone that works on them, i called a few places that just sell the machines, but they only work on ones they sell, so im basically stuck. I'll definitely try to be careful with anything i remove.
