Lethal Enforcers sounds like it's falling down stairs Before I get started, I haven't worked on boards in maybe 18 months. So while I've searched around, things may have changed on repairing these. I *think* it's the custom Konami chip SMD caps like in the X-Men sound issues thread. I've...

I'm working on a K7000-A (Zenith model) that's blowing a fuse on power up. I have a flyback and cap kit for it already, and I'm ordering a new HOT and Voltage regulator, but I have a couple part questions. What value is R96? The solder was so eroded that I could pull it out with little effort...

Not sure what I'm looking at here. Our MKIII started getting blurry, so I adjusted the Focus, which worked fine. Then, it would come in and out of focus randomly. So, I decided to hedge my bets and do a cap kit. Now, when it comes on, the top of the screen is fine, but the bottom half looks...

I'm not a monitor guy, so I'm probably going to get a bunch of eye rolling from this. I'm working on a WG 7500 in a dedicated Gauntlet: Dark Legacy. I capped it a few months back because we'd occasionally lose green. Then I went back into it and changed out the Color Drive transistors on the...

Pigskin 621 AD with glitchy graphics. I'm working on a Pigskin, and aside from the monitor being pretty bad, the character sprites are flickering in and out everywhere on the screen, even on the test screens. I tried reseating all the socketed chips, but that apparently didn't help

I'm working on a Super Bank it we got in a few weeks ago. I've got no sound and I'm looking for a manual of some sort so I can determine what the DIP switches do.

I capped an X-Men sound board the other day for a guy, and plugged it in to test it out. The sound was there, which was the goal, but I saw that it still had some glitchy video going on. It was there before I played with the sound chip, I just want to solve it, too On the far left, there's a...

I'm working on a Daytona USA 2 that keeps hanging up at the startup screen. The wheel calibrates, then the wheel jerks and nothing happens. Any ideas? I've readjusted the power supply and reseated the boards, but no luck. This problem has happened before (or at least similar symptoms), but...

So today I was trying to figure out why my Mario Bros. game isn't giving me any digital sound after I had replaced the three VCOs and chips 5L and 6K, which seams to solve most problems from the forums. Poking around with my scope, I seem to have a signal until I get to MXR1. The manual I...

I'm working on a Vs. Unisystem Super Mario right now. Thanks to lilman, I have Mario back instead of a silly Skate Kid hack. And thanks to Bob Roberts, a fresh set of caps on both the monitor AND the sound board. My problem is that there is still no sound. I switched audio boards with our...

I'm working on an old Toledo pinball. When I put in a credit and pres start, the scoreboards reset to zero, but the player two scoreboard will not stop clicking through. It's on an endless cycle it seems. Any help?

I'm building an icade 60 in 1 and it's not going well. A few weeks ago I plugged it into a cabinet with a good power supply and it wouldn't start up. I couldn't get into the test screen either. LEDs 3 and 5 stay on with no change. I took it out of the cabinet and plugged it into an NBA Jam...

My boss bought a Johnny Nero the other day and I've been working on it for about a week to try and get it up and running. I've checked the power supplies and both look good, but I'm having an issue with the 24V one. If I hook it into the gun's wiring, I get a hissing noise every couple...

I'm having to ask just to clear the doubts out of my head and my boss's. I'm sure the answer is "Cap Kit" Got this monitor from a local business that handles a lot of route based coinop, including for some games in the arcade I work at. The monitor looks ok, but we don't know what's causing...

Cut the Cheese LCD problem (that and searching for a manual) The arcade I work at has a Sega Pinball Cut the Cheese redemption game that has a few annoying issues about it. The most annoying thing about it is the LCD. I keep seeing it flicker or have some sort of noise problem that garbles...

Forgive me if this is the wrong place to post about this game, but I figured this was the closest one. I am working on a Wacky Gator. More or less, it's a complete overhaul job. Only One gator is working currently, but that's not my issue at hand. My question is about the lamps for the...
