Here is an interesting problem I ran into with a pinball machine on location. I will be paying attention to see if this is an isolated random thing, or a potential design problem?

Bringing an old KISS pinball machine back to life
A friend brought in a game to the shop that is a really beautiful Kiss game and we’re going to update it with new tech and make it better than ever.
Here are the following parts:
Diagnosing Stern Spike 2 Node Board Problems With Jaws Pinball
In this video I dive into diagnosing an error condition with a 48v node board for Stern’s Spike 2 pinball system. In this case, I have a Jaws Pro where most of the switches went out and a lot of coils stopped working. The machine says “Node 9 not found” so we’re going to take a look at what the problem is.

The fin up kicker coil was fried and shorted.

Here is the damaged Node board 9 – there’s a driver transistor that exploded and isn’t there in the middle

On the underside of the node board, there was a bunch of corrosion. The problem is, there’s no indication of where this came from? It’s at the top of the playfield underneath the playfield, not near any area where any cleaning solvents could lead, and I didn’t use any cleaning solvents on the playfield. It must have come this way from the factory.
Diagnosing Issues With Stern Deadpool Pinball Katana Ball Lock
In this episode I hilight some issues you might experience with Stern’s Deadpool pinball game. In this case, the Katana ball lock may eventually fail due to a part that can wear out or break.
Here is an update with more information on how I’m “bullet-proofing” this mech so it doesn’t break again.
Stern S.A.M. Walking Dead Pinball With No Sound – How To Fix?
I’ve encountered an odd problem with this Stern Walking Dead pinball game. The sound completely went out. But there is not a dedicated sound board. So what do you do? It’s a lot scarier than one would think…. This is part one describing what’s going on and what I’m doing about it…
Will UV Gel Work To Fix Worn Pinball Playfields?
In this video, I am testing a technique that some have been talking about, using a special gel that will cure under UV light to fix playfield damage. I’m using what’s called “Bondic.”
Note I say “infrared” but I obviously mean “ultraviolet.”
What’s your experience with this product?
Bally Embryon Pinball – First look and initial repairs
I’m very excited I was able to pick up one of my grail games – an early 80s Bally Embryon. Here is some of my progress.
In the next video, I begin to go over what’s wrong with the game and work on it. First order of business is dealing with flippers – on these Bally games, there are some issues with EOS switches.
Next we move onto dealing with drop targets.
