I was having weird things happen with my Twilight Zone… what was causing the problem? Optos? Switch Matrix problems? Connectors? LOL… nope
This is one of those pinball pickups that we all dream about. It took me awhile but I finally had one of those experiences. A top-5 grail game, in HUO condition? Way below market value? Sign me up!!
This is also one of those games I’ve toyed with selling on and off because it’s so beautiful and desirable, but so far, we’ve kept it.
Here are some pictures of the game showing its condition:
Probably one of the most common problems people experience with the modern Bally/Williams DMD machines are random resets of the game in progress. Sometimes it appears these resets happen at certain times (like when you hit a flipper or during multiball) and you think it may be directly related to that. Most of the time, that’s not the case, although heavy activity like firing certain solenoids might cause a drain which exposes a weakness in the game’s power system. We’re going to go over the standard procedure to deal with this issue.
After the board is removed, I go over the process to desolder and remove components.
Now time to solder the new components on the board. You have to be very careful to not mess up the traces. There are also some recommended jumpers you can run around the bridge rectifiers to double-up on the traces. I don’t go into that in the video but you can look at Clay’s guide for more details on that.
Another thing you might want to do if you do not replace all the caps, is to mark on the top of the cap the month/year you replaced them. This way in case there’s any confusion, you’ll know which components are newer and which ones may still be original.
And now the moment of truth!
