S2000 Reel 1 Tilt Question

[djhannu]

I recently found a IGT S2000 series slot machine for sale that was listed as ‘not working’.  I bought it hoping I could fix it without dumping a lot of money in it (that can wait until it’s fixed).

I turned it on and got the “Display’s NETPLEX link is down”.  I did some research on this forum, and it pointed to a power supply problem.  I pulled out the power supply and found an obviously blown capacitor.  I re-capped the entire power supply, reinstalled it, and powered it up again.  This time I got a “Game EPROM CRC Mismatch -0xB000001” error.  Again, info on this forum pointed to an MPU problem.  So I pulled out the 502 revA MPU and found a dead coin cell, and a slightly leaky Varta battery.  I removed both batteries, cleaned the acid off the board, and reinstalled the coin cell in a new holder.  Popped the board back in the machine and got the same error.  More research indicates I might have damaged traces on the MPU from acid damage.  I pull out the MPU again and check the traces, find that there’s no continuity on two of them, so I solder on a couple of bodge wires.  Installed the board back in the machine and powered it up.  Now the center reel spins on startup, but I get a “Reel 1 Tilt” error.  I check the reel connections and even swap reels, but only the center reel works.

Is there anything else to try before I admit defeat and buy a new MPU board?  Where’s a good place to buy a board without spending the $200-$300 that they fetch on eBay?

Thanks.  This forum has been invaluable so far.

Out of curiosity could you tell me which game chips are in it?
