    🐀 It's been a while since I've had to repair a insect and rodent sanctuary. The cabinet and backbox of this game were full of wasp nests and rat poop. So this game needed a pretty deep clean before I could tackle anything else! The primary issue was the game would not boot. A combination of destroyed fuse clips and leaking capacitors on the power supply were the culprits in this case.


    Once the game booted up, I could focus on the many other issues. Unfortunately the rat poop was not the only evidence they left behind; they also chewed through a bunch of wiring at the base of the cabinet as well as in the backbox. This resulted in a lot of game features not working including some lamps, flashers, the shaker motor, and a couple of switches. Those little teeth sure do a lot of damage!


    A few small issues to round out the repair. The balls were getting stuck in the trough. The trough was very rusty, and the balls were getting caught on the rust spots. Some rust converter and a clean made things nice and smooth again.


    Most of the insert lamps above the flippers were out. Bulbs, sockets and connectors were eliminated as the cause. Turns out, these lamps are all in the same column, driven by Q70 on the MPU board. Q70 had failed. Once replaced, the lamps were turning on again.


    A bunch of other parts needed replacing. New drop target. Couple of new switches. New balls. New rubber rings. New lamps.


    Machine is almost at 100% now bar a couple of minor issues, and is fully playable, which is much better than it was before I turned up. Ready for "action"! 🎬

    Teenage Mutant Ninja Turtles #2 (Prototype Conversion!)

    We've been here before! Last time I wrote about repairs to a Teenage Mutant Ninja Turtles (TMNT, Data East, 1991), I was discussing a restoration I performed for a customer. This machine was a little different. I bought it after doing some repairs for its previous owner. They decided to move and didn't want to move the game with them, so they sold it to me instead. ​It's a weird experience to start repairing a game for somebody and then finish repairing it for yourself. Suddenly you're not constrained by time frames or repair budgets, and you can really take the time to make sure the game is playing as well as it can be. You can also take the time to make any improvements or modifications that you want. And with all of the extra features I planned to install, I needed a lot more time than most people can justify in a regular service call. But what "extra features" am I referring to?

    Jurassic Park (Data East)

    I haven't had to do a full restoration on a Data East machine in a little while, so it was about time one came around. Enter Jurassic Park! This machine came from a customer who had this machine sitting in their garage. They had just moved house and wanted the machine brought back into playing condition so they could play it in their new house. As expected, the Jurassic Park was much older than the house, and was also in much poorer condition. The game did start up and enter attract mode, but a lot of playfield features did not work and a lot of parts were broken. This was going to be a full-on restoration, and I wanted to add a few little touches to really bring the machine back to its former glory. ​So, if this pinball machine was 65 million years in the making, then I was in it for the long haul with this restoration.

    Guns N' Roses

    Many people consider Guns N' Roses (Data East, 1994) to be one of Data East's best pinball machines. One of the few rock music machines from the 1990s, it is a really cool game with some interesting design decisions incorporated into it. While a lot of people prefer the more modern music themed games such as AC/DC or Aerosmith or Metallica, I still prefer the older games, so Guns N' Roses scratches that rock theme itch perfectly.

    This will be a shorter blog post as this was not a full restoration by any stretch.  There was limited disassembly performed and pictures were only taken of the issues I was tasked with fixing. My customer had pulled the machine out of his warehouse for the first time in years and wanted it to brought back to working condition. No cosmetic fixes and no fancy stuff. I just needed to get it back up and playing. So, I won't bother with the standard descriptions of the machine's condition or nitpick the defects. However, I performed some interesting repairs on this machine which warranted writing some of them up. So, let's jump right into the repairs!

    Check Your Capacitors! Data East Power Supply Corrosion Repair

    Circuit Board Repair Data East Frankenstein
    I haven't been posting much lately, nor have I been able to take on much repair work due to a house move (more on that later!). However, I've been able to get stuck into a small backlog of board repairs and other minor jobs while I sort out the housing situation.

    After the last repair, I thought it would be a good idea to do a short post to remind everyone to check their circuit boards as a part of their regular pinball maintenance regimen. Circuit board parts fail all of the time, but few of these failures will actively damage your machine. Batteries are the most well-known exception and they will certainly damage your circuit boards if they leak. However, fewer people are aware that capacitors are capable of damaging circuit boards in the same way, and should also be checked regularly for signs of damage.

    Last Action Hero

    Last Action Hero (Data East, 1993) came to me as a restoration project for a customer who had had the machine for some time but was moving it to a new location. He wanted it to be fully working so he could set it up in his factory. The machine was relatively functional, but had a few issues that required extensive repair. I have a soft spot for Data East machines, so I was keen to take this one on and see how a full restoration would make it pop like new again.
