I’m repairing an A/R III board and noticed C18 is cooked. The parts list for it says it’s a 0.1uF 50v Ceramic Cap but it looks more like zener diode. Does anyone know exactly what it is?

I have a KT-2725 that has good B+ but no neck glow. I checked the manual and the troubleshooting chart just says to "check filament circuit". I'm not sure how to find that circuit from the schematics. Can I just check the heater voltage at the flyback or neckboard if I know the heater pin and...

I recently recapped a monitor because the sync went out thinking it might fix it. Nope. It has still has zero sync. By that I mean ZERO. Its all over the place horizontally and vertically. In fact, when I move the sync wires around it doesnt respond at all. Like the sync is completely dead. I...

I recently started working on a friends Pacman that he had in storage for decades. The G07 in it was working but had all original caps. I installed a new cap kit including a new filter cap. Now I've got around 50 VDC on both sides of R1 with no load. Under load it drops to basically 0 VDC. I...

I'm new to PCB repair and wanted to post a recent Pac-Man PCB repair i did that might help someone else with the same issue. I had an issue with moving sprites missing. You could see pellets/dots disappearing as they were being eaten but no pac-man or ghosts were visible. I checked out the...

It’s my first time turning this HeliFire on and the colors are wrong. I thought it was the monitor at first but I hooked it up to my TPG and the colors are perfect. So maybe it’s the board set? Any ideas of what’s causing this?

I was recently tasked with replacing the wiring harnesses for the Poltergusts on a friend's Luigi's Mansion. He asked to make some type of boot for the harness end that connects to the gun so it doesn't wear out as fast. The issue is that those cables have large brackets and stuff already...

I have a Star Wars Deluxe with the 50" Toshiba projection. The convergence just randomly got really bad all of a sudden. I have the original remote but the convergence adjustments don't respond. I can adjust everything else. Does that mean the convergence chips are bad?

I've got a K4900 standard res with no HV. I followed the flowchart and checked the usual suspects... F501 - Good R503 is reading 154 VDC on the leg closest to F501 so I replaced IC501 as well as C507 - no change. HOT is good. Reflowed all jumpers as well as all the areas around the VR, HOT...

I'm sure this has been asked a thousand times but I've noticed a lot of similarities among the Midway cabs. They all look the same for the fighters. I've also noticed the sports titles looked alot alike as well. Midway fighter cab - MKII, (U)MK3, MK4, Killer Instinct, Killer Instinct 2...

I need to make a new cover for my NBA Jam control panel. The old one is cracked and worn out. Has anyone ever used a router on plexi for something like this? I’ve done tons of wood but never plexi. I was going to lay a new piece over the old one and use it as a template and trim it with a...

I recently purchased some t-molding that requires 3/32 slot rather than 1/16. They didnt offer it in a smaller size and I really want to use it. Does anyone have any tips for getting it to work or is widing the slot the only option?

Does anyone know what the most common poly laminate is for cpo's? Specifically the thickness, brands, etc? My local sign shop that has done all of my arcade print work for years told me a few weeks ago they ran out and would have to find a source for it. After a few weeks of waiting they finally...

I have an HP scanjet 4600 that I’m trying to scan a glass bezel with. The scan is slightly blurry which I feel has to do with the thickness of glass. I’ve noticed that marquees are the same way. Does anyone have any suggestions for scanning glass bezels/marquees to prevent this?

I recently got an Offroad thunder that did not have a monitor in it. I pulled the pc out to check and make sure it was working first. It appears complete with the original 3dfx Voodoo card. It sounds like its booting up but everything I connect it to with VGA (straight from the graphics card to...

I recently acquired a Code 1 Dispatch with an "RTC SELF CHECK BAD" error. Reading through other posts it seems this particular Konami Viper game isn't easily fixed when it comes to RTC problems. Has anyone successfully fixed this particular issue?

I recently bought a Power Drift upright model and it's missing the gas pedal. If anybody has a pedal they'd like to sale or if you know of a good alternative please let me know. Thanks!

The hard drive in my Road Burners was starting to fail so I decided to replace it. The original was a 160GB Maxtor IDE and I replaced it with a WD 500GB SATA (using an IDE to SATA adapter). I wrote the CHD image to the new HDD using CHDMAN. When I power it on it gives the error... found no...

Walked by my Simpsons this morning and noticed the screen was badly distorted. Tried a 60 in one board I had laying around and got the same thing. I pulled the chassis and put in new caps as it was badly needed anyway but the problem still persists. Possible IC issue on the chassis maybe?

Recently picked up one of these on the cheap. Starting to understand why it was so cheap. Worked great for a few weeks but then it started becoming unresponsive and would hang up during a game. Now the sound is completely gone. I tested the motherboard by booting into a live linux bootable USB...
