    Default Thinking of recapping my neo-geo cab

    I've got a neo-geo 2 slot arcade monitor, that looks fuzzy (not very sharp). I'm thinking I need to recap the thing, but i'm clueless as to what I need to know. I've tried every adjustment to the colors and hues to make it look as good as possible, but its like playing a game through smudged glasses.

    Some questions i have:

    1) How do I tell what kind of monitor I have?
    2) Where can I get a cap kit from?
    3) Is my problem likely related to the capacitors?


    I'm aware of the dangers of these monitors, so i'll be very careful in working with it. I'm also fairly good with a soldering iron, so i'm pretty confident I can do this myself.

    If someone has done something similar with a neo geo cab, i'd love to hear about the steps you took to recap your unit.

    Thanks.

    Did you try to adjust the focus knob? Is the screen filthy?

    1) post pictures.
    2) you can order a cap kit from lots of places, but the big two are Bob Roberts or Zanen Electronics.

    I would register at Neo-Geo.com and post this question on their boards. You will probably get better answers there.

    If you order the cap kit from Bob Roberts, it'll include instructions about which caps go where. All you need to do is DISCHARGE IT (so that you don't die), take out all the plugs/screws, replace all the caps as per the included instructions, and hook it all back together.

    EDIT: Also, when ordering the cap kit, know which model your monitor is. The caps you'll be replacing are on the chassis, NOT the tube. The "chassis" is the circuit board in the back. You'll find the model number Bob will need on that chassis.

    It could never hurt..

    Monitors always look factory fresh after a proper cap job. And it means you won't have to worry about most major problems again for a long while.

    Post a pic of the monitor, if you can. We can probably figure it out by looking at it.

    I believe most Neo cabs have WG monitors, I believe. And if it's a K4600, be prepared to get extremely frustrated. Whoever designed them didn't take repairs into consideration. It is the most poorly designed, and most frustrating monitor I've ever worked on - The width coil is attached to the chassis, not the PCB. Fixing a busted coil is next to impossible.

    If it's got 2 small boards connected to the monitors main board, it's a 4600. If it's an Electrohome G07, consider yourself lucky. G07's are a breeze to rebuild/cap. If you need a cap kit for a G07, I can hook you up - I have a ton of Xicon caps left over from the 3 monitors I recapped last fall.

    Another issue can be the tube is dying. I had a monitor with a new flyback, and capkit and it still wasn't sharp. My buddy ending up having to rejuvinate the tube. This can also kill the monitor if done inmproperly. Rejuvinating also isn't a 100% fix as occasionally the tube can revert to the way it was prior. Haven't had that happen to me yet but I hear it can happen.

    Super helpful.

    Without knowing if he's even tried to adjust the focus pot, there's no need to recap it yet. All he mentioned was adjusting the color pots, which has zero to do with focus.

    If the screen is filthy, it could also contribute to the issues the OP mentioned.

    Fastest way to figure out what monitor is in there is to post pictures. We don't know if it's a dedicated Neo cab or what it might have been converted from.

    Thanks for all the replies.

    I managed to capture a label that says Model 25K7191.

    I did a google search and it looks like its a Wells-Gardner model.

    I've cleaned the entire front of the screen - its definately not a dust issue.

    Perhaps someone can point out the focus pot? (images are listed below)
