How to Fix a Pinball Machine’s Score Display

Just did another pinball video. This one was on my Paragon pinball machine in that one of the score displays had missing segments on the bottom. When there are missing segments it’s usually the IC chip, transistors or resistors. I replaced the IC chip and one transistor in this video. Plus you get to see my solder in the IC chip socket. I know exciting stuff! Here’s a chart to help you figure out what to replace.

 

The Purple ESR Meter testing capacitors

I own two different ESR meters. I call them the Blue meter, you know the one that comes in a kit and you put together and then the Purple meter. What’s GREAT about the purple meter is that it not only shows you the ESR of a capacitor, but also the capacitor value. This is great for testing used capacitors or new ones before you install them.

Buy the Purple meter here, it’s the same place I got mine from.
They have fast shipping and answered my email questions in a timely manner.

How to replace a 3-prong electrical plug (on asteroids)

Every arcade machine or pinball machine I own needs to have a 3 prong plug. Meaning that they need to have the ground plug. I would say at least 25% or more of the game I’ve added to my collection has had bad plugs, the ground plug cut off or broken and a loose plug. So if the cord is still in good shape you can just replace the end 3 prong plug. Here’s a video I made of me changing one on my Asteroids machine. It took about ten minutes. With just a minor set back when the new replacement plug I bought was missing the screws!
