content: I am wondering if anyone has the schematic or even the front panel wiring diagram to this poker machine? This is the table top version of this game like this:how ever I have multiple problems with it (lights don't work, screen has a purple tinged circle in the center, no sound). I have found two loose wires on the front panel as well as a very burnt looking resistor on the main PCB as well as a blown trace that goes to a power transistor that may be for the lights (I think this trace may have been blown by that fact that the PCB at one point touched the bent metal chassis at one point).

content: You might try posting on the KLOV forum, or one of the other arcade collecting forums, most of the arcade collectors I know are not into poker machines but there have got to be collectors out there who have them. People here can help you with general troubleshooting but most of them are not going to have expertise specific to a machine like that.Is the display a CRT or LCD? If it's a CRT you could try degaussing it to correct the purple, but it's possible it took a hit that deformed the shadow mask.

content: I tried making an account on the KLOV forum but I could not figure out how to fully log in, I think it may require a payment or someone to recommend me to get fully signed up and I don't support those non open type of rules. The display is a CRT and the image is sharp but has the purple circle in the center of it. I can take a picture of it if that helps. I did find these two links to extra info about this unit:https://www.arcade-museum.com/manuf_detail.php?manuf_id=172https://www.arcade-museum.com/game_detail.php?game_id=19260

content: I would try degaussing the tube, if the internal degaussing coil has failed then you'll get weird colors, that's called purity error. It can also happen if the tube has been dropped or hit causing the shadow mask to shift, or the deflection yoke could have been moved.

content: I don't think it has a degaussing coil as I don't hear the sound that it would make when activated. I do have a big coil from a 27" tv that I scarped would that work or would I have to fold it in some way to make it small enough to work (I was thinking of twisting it 180 on one side and then folding it over on itself a few times but I don't know what that would do the magnetic field. Or would I have to make my own and run it off a low power AC transformer?

content: You can absolutely fold up a larger coil into several turns of a smaller diameter, I've done that before. A salvaged coil from a TV will heat up pretty fast if you connect it straight to the line since they normally only operate for half a second or so but if you put an incandescent bulb in series that will limit the current.The little degaussing coils used in small monitors like this normally don't really make much noise though.

I've spent a great deal of time cleaning up damage from leaking NiCd batteries on arcade boards, Qbert and Omega Race are particularly notorious for this, same with Amiga computers. When the battery leaks it makes a real mess. The lithium thionyl chloride batteries used in the old Macs are even worse.

content: I usually run them through the dishwasher, use only about 1/6 the usual amount of detergent though. Other things I'll put them in the sink, spray them with Oil Eater and then gently scrub with a soft bristled brush, rinse thoroughly with hot water and then set it out to dry for a few days. If I'm in a hurry I'll follow up the rinse with a rinse in alcohol which rinses off the water then evaporates quickly. If you have minerals in your tap water then a final rinse in distilled water would be a good idea but I don't have that problem here. Try to avoid getting water into the focus/screen pots as those take the longest to dry out if they get damp.

content: I tried washing it in the sink with just hot water and abound 90% of the crud came off. If I really care I could take the garden hose sprayer to it when the weather warms up. The metal parts are still somewhat stained brown but that I don't care that much about. I at least can now read the values on the components. The one cap that I think will be hard to find is the 10uF 35V nonpolar that is in the horizontal output section but other than that I think all the other electrolytic's are low voltage types as this monitor only runs off 13.2V AC that is half wave rectified from two taps on the transformer with a center tap that is grounded.

content: Well I finally got some more time to work on the system. I have started taking apart the front button assembly's and have found that the switches are made in Japan and have lights in them. I cleaned a set of the buttons in my ultrasonic cleaner and I think I may have killed some of the remaining working bulbs (is that even possible?). Anyways I am now wondering where I could find some compatible replacement switches. The closest match I could find were these ones:http://www.shinden.com/PushButtonSwitches/p-101a-06.htmhttp://www.shinden.com/PushButtonSwitches/p-101a-05.htmhttp://www.shinden.com/PushButtonSwitches/p-101a-04.htmand a measurement diagram of one:http://www.shinden.com/images/push/appr/p101c04rbst0000.pdfI have attached pictures to this post of the switch that I have disassembled to see if I could fix it. I have also found some literature for the system:https://flyers.arcade-museum.com/?page=thumbs&db=videodb&id=4274(you would have to be strong to hold the unit like the ad as it weighs around 50 pounds). I also have taken the time to reverse engineer the front panel pinout (not sure if it is correct though), if anyone is interested I will do a write up on that.

content: @Tech13I am not sure that you can replace the bulbs with LED's as I think they are controlled by triacs and those only operate on AC. I think all of the lighting circuits on this unit operate on AC. Think of what is in a standard light bulb dimmer. They do not work with most non dimmable LED bulbs as the voltage across the LED's cant easily reach 0V like a filament in a normal bulb can (not enough load on the dimmer). By the way your buttons should all light up as well. Monitor looks good though. Be careful with the exposed PCB like that as some of the tabs on the triacs are at mains voltage! Mine already had a PCB track explosion when I got it due to the electronic lock for the cash drawer being removed and the wires not being isolated correctly and the full120V mains shorted out and took out the track and the triac. Luckily nothing else was damaged.

content: @Tech13After looking at the schematics that have been posted I think you have the version 2 or 3 unit. This does use DC for the lights so that is why your LED replacements are working. It would also explain the lack of PCB for the switches. There is also no 120V AC running the coin door lock either so you are safe in that regard as well. Your monitor on the other hand does use 120V AC so that is different from my unit which only uses 15V AC center taped.
