Today I’m testing some new LED displays that come from Australia.
These new LEDs are a drop in replacement for the standard high voltage displays, but use less power and look almost identical to the original displays.
They’re produced by Wayne Hamilton out of Australia. Here is where you can find his products:

The woofers that Stern puts in their games are pretty flimsy. If you accidentally drop the playfield on them – ooops, you can dent the frame and make the speaker sound like crap. So now I have to replace this speaker but you can find far better quality replacements on Amazon that will drop right in. Here’s a quick video on how to do that without having to spend $100+
I occasionally like to refer back to this reference I made awhile back and I don’t think I had it posted on my site, but when working on WPC driver boards, it’s very easy to damage traces that connect opposites sides of the circuit board. Here’s a handy diagram of those traces and recommended jumpers to make the board more reliable.
When diagnosing power problems on the WPC driver board, it’s a good idea to check for continuity between these marked traces. This can indicate a blown thru-hole.
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…
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?
This is another in my “Occam’s Razor Pinball Fixes” series. These videos demonstrate the principal of Occam’s Razor, which states, “The simplest solution is the most likely” and we often forget this.
In this case, I couldn’t get Haunted House to start a game.. the fix was significantly easier than what I thought it would be. (And no, it’s not because there wasn’t a ball in the machine.. LOL)
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.
