Hi everyone,
So, I seem to have really messed up my getaway
It was working absolutely fine until a few weeks ago, when I pulled out the power driver board in an attempt to diagnose some problems on my T2. I ran into some additional problems on the T2, so I gave up for the time being and went to return the power driver board to the getaway.
Well, now the machine doesn't work properly. I got the power driver board back in and reconnected everything. The machine powers on OK, the MPU board completes it's bootup sequence, and the playfield lights up as it should and begins attract mode. Also, if I press the start button, a ball is launched into the shooter lane, and I can fire it into play with the shift lever...
HOWEVER, none of the boards other than the power driver board and the MPU board seem to be working at all!
The symptoms are:
-Flippers don't work (the getaway has a fliptronics board)
-No sound, just a little hissing from the speakers during boot up
-The DMD is blank and never shows anything
My power driver board is a rotten dog board. I tested all of the test points, and they are all good. I also tested for power on the 3 boards that aren't working right (sound, DMD control board, and fliptronics), and they all seem to have power.
Next, I suspected the ribbon cable might be bad, since these 3 boards are connected to the MPU board via one ribbon cable with 4 connectors. However, replacing all of the ribbon cables with new ones didn't change anything.
I also tried disconnecting the ribbon cable and tried booting with one board connected to the MPU board at a time (for example, I just connected MPU and fliptronics, then MPU and sound, then MPU and DMD control board). However, none of the 3 boards worked when connected solo like this either.
I even grabbed a new power driver board, in case somehow the board went bad in the T2, but the behavior is exactly the same with the new board as well.
I'm currently totally stumped by this. The game WAS working fine, as of when I pulled the power driver board. I don't see anything wrong or burned out, and I double checked every fuse in the machine. Is there anything else anyone can thing of that could cause this behavior? At this point, I'm starting to wonder if the MPU board somehow went bad, but this seems absurd to me since it boots properly, controls the playfield properly, and it's a new rottendog replacement board that worked fine as of when I yanked the power driver board.
Thanks!
