So I finally bought my first game over the weekend and got it home in one piece! I went in to the deal knowing it didn't work, which is what I wanted so I could try learning a little bit, not to mention the satisfaction of bringing a dead game back to life. I'm pretty sure I've isolated the issue, but I could be wrong and any thoughts are appreciated. So, here's the back story:
Contacted the seller on CL, she's selling the game for her son and informed me the flippers did not work. She said the lights turn on, plays the startup sound, solenoids fire, etc... At this point, I'm okay with this. I figure it can't be too many things. The game was given to the son by a neighbor as a gift about 4 or 5 years ago. So I get to her place to see the game, and it's in really really good shape. I open the coin door (already open, no key) and pull the playfield up... And neither her or the son knew this was possible. I am now worried.
I look under the playfield and nothing looks out of place or broken. I turn the game on, get a start up tone, open the coin door and press the switch to give myself a couple of credits to play a test game.... And nothing happens. I figure its time to open the backbox and take a look at the boards to make sure everything is connected and that there hasn't been any corrosion anywhere (epic foreshadowing). I find out minutes later that they have never had a key for the coin door or backbox and it hasn't been opened since they've had it. Anyhow, i tell them the likely reasons that the game isn't starting and was able to negotiate a price that I thought was fair keeping in mind that I probably have a big fix to go on behind the glass.
So I got the game home yesterday and was able to pick the lock and found the MPU to be in the condition shown in the picture below. This is my first go around, but I'm assuming the battery corroded and basically ruined the board. The book said the LED on the board should flicker once at power up, followed by six quick flashes and the start up tone, indicating that the MPU was functional. Well, upon turning the game on, we didn't see a single flicker. So I guess I'm just looking for a confirmation that this is in fact a ruined AS-2518-35 MPU. If so, I know they make reproduction boards, but where should I get it, and what do I need to keep from the old MPU to put on the new MPU. All other boards were fine with no corrosion. Any help is really appreciated.
