So, what the subject says. The volume pot still crackles through the speakers so I know the amp is working. I've reseated the audio cable going from the board to the audio amp... What's next?

Our Terminator 2 machine just decided to freak out and scramble most of the sprites. On boot it shows a ton of bad ROMs but I doubt they are actually bad, or at least not so many of them. See pictures; the right half of the screen is dark but I'm about 95% sure that's a monitor issue. So where...

The MK1 machine at the barcade almost always has an issue when they flip the power on to all the machines... Everything powers on, but nothing shows up on the screen. It's sort of a bright black (does that make sense?) screen that fixes itself if you power cycle the machine, including just...

We had a DK machine in our warehouse that just received a recently-serviced board to replace our old semi functional one. I got everything installed and played through several levels with zero issues. They moved it down into the bar, and now the colors are wrong. But not all the colors! The...

The guys at the bar tell me (but I haven't had a chance to verify) that Centipede has started acting weird. The trackball doesn't move your player at all... until you die once. On second man it can move, but won't move down until you give it a hefty upward spin. It does the same...

I got word that the TMNT machine at the bar wasn't working. It's a 4 player machine that has either been modified or built out of something else. It's all very clean, has a widescreen (COME ON!) LCD in it, and the board is clean. It'd been running hard without a hiccup for weeks and weeks. So...

I'm replacing a Donkey Kong board with one that's a pretty different foot print. The old one was 4 boards mounted to a metal plate that slid into some wooden tracks inside the machine. The new board is two PCBs held together with the white spacer/supports shown in the attached picture. The...

Our Defender machine suddenly started booting to a white screen with scrolly vertical lines. Dropping a coin in doesn't play the coin noise, so I am guessing it isn't a monitor issue. I re-seated all the connections between boards and got no change. Where do I start testing? Is this a power...

A barcade just opened in my area, and I've been given the opportunity to try and fix some stuff. I know enough to be dangerous and can usually figure out problems that I can see manifesting themselves on-screen, but the ones that don't boot up are a little intimidating to dig into. Case in...

The player two coin slot doesn't seem to operate on this machine. The confusing part is that the test screen shows that switch registering when I drop in a coin, so the switch and wiring is correct and communicating with the machine. I don't get it!

I'm trying to get a TMNT cabinet to behave correctly. I've got the DIPs set so that it's one coin to start a game, but for whatever reason it takes two coins to continue. All the stuff I've found online about those DIP switches don't list anything about start credits vs continue credits being...
