Heh, when I read your post about reseating the connector and everything working the first thing that crossed my mind was that won't solve the issue for long... I am going to say you've either got cold / broken solder joints on the switch matrix headers, or the header pins and connector pins are...

OMG I'm dying here.... LOL D

Congrats Rob, and whomever the new owner is. D

Good stuff, and this is just the beginning! Keeping these things running 100% is what I enjoy the most about the hobby. Enjoy... D

One of my favorite seminars at Expo 2010 was when a large group of the designers from WMS got together to talk about some of their favorite stories / memories and Granner's tales were by far the best of the lot. The story behind T2 and the swear ROM's and how the game almost never got released...

The best advice I can give anyone when working on stuff like this is don't over think it. D

Opto's generally are more robust than micro's, and were used in places where using micros' are difficult or impossible to use. Once you get it set right, you shouldn't have issues with it. D

Once you get your manual you will understand better, but the switch matrix is an 8x8 "grid" of switches that is found in most late model games. Physically it is part of the PCB set in the head (usually on the MPU). D

Could be, but it would depend on where the post that splits the two in-lanes is located. If it's high up, then I would agree. If it's in line or lower than the post between the outlane and in-lane not so much... D

I would highly suggest you do NOT convert from opto to mechanical switch. The amount of time and effort you'll go through to accomplish this Tim, it will be WAY easier to replace the opto's in your game with new ones. There is no reason you should be having to adjust these, so something isn't...

Ya, this isn't an issue you want to be having... especially where it's intermittent could be tricky to track down. Without over-thinking the issue too much, I'm going to say hopefully all of these switches in the game are all on the same row or column (you will need your manual to confirm...

It means there is a break in the coil winding somewhere. Tug on each strand and see if you can pull one of them away from the lug. As log as the break is close to the lug, its repairable, just unwind it one turn, sand off the coating and resolder t to the lug. D

OK, not sure if gtb is the same as wpc, but if the coin door is open in test the coil power is cut off. Run the test again and close the door just to make sure. If the coil still isn't working, put the game into attract mode and test for voltage at each lug of the coil to ground. Dmm on DC...

Tim, Most likely not the coil. I'm not at my PC right now to type lots, but don't order a new coil yet. Too many other tests to do first. D

Alright, last one for tonight... This one was a little interesting because there is history between this particular game and myself. At some point last year I had the pleasure of meeting Warlock (one of the nicest, most sincere people you could ever meet I might add) at one of the many pinball...

While I'm still relatively awake figured I'd keep the posts coming... I got a call about an Addams Family that was having a reset issue, a flipper issue, and the owner had also bought one of the new ColorDMD's for the game and asked me to install it. No problem. First up, the reset. The...

Alright, finally forced myself to sit at my PC and start organizing all of my notes and pics that I've been collecting over the past several months of various repairs that I've done on various games. This is the first time I've ever really "blogged" anything, so forgive me if things are not...

Ok, after watching the hockey game last night I somehow managed to find some motivation after a couple weeks of having zero. I repaired a Stern Whitestar driver PCB that Warlock dropped off to me. I also started working on an entire set of Zaccaria PCB's from Drano's Farfalla and so far have...

This was my old game... if that helps with the sale. :) D

Thanks! Here's hoping it only gets better with age. 8-) D
