Today I picked up a Capcom Breakshot off of CL. It has been sitting in a shed for who knows how long. It wasn't booting or doing anything when we got it home, only the GI came on. After going over the connections and replacing a few fuses, the game boots and plays. All switches, solenoids seem to work just fine, as does the sound.
What doesn't work is the DMD and the controlled lamps under the inserts. The "GI" string of lights is working just fine as are the flashers.
First the DMD. The DMD is dead as a hammer. I have not checked in another game yet, as I do not have another DMD in the house. I pulled up the schematic and started checking voltages on the DMD power supply. The +5v is just fine, but the 18v on two of the pins coming from the main driver board is non-existent. I have checked the plug on the driver board and there are 0v where 18v should be. Looking at the schematic, both 18v lines should run through C97. Problem is, there is no capacitor at C97. There is a spot for it, but nothing there. It doesn't look like there has ever been a cap there, but I could be wrong. From looking at the picture below, pulled from IPDB, there doesn't appear to be a cap there on any machine. So, tracing back it goes through D33 and R412 before it gets to LED2 on the driver board. LED2 is lit, so I am assuming it is getting the correct voltage. Neither D33 or R412 look burned up. Could one of these two components be my problem, or am I misreading all of this? Like I said, everything except the DMD and controlled insert lamps is working fine.
The insert lamps are not working at all. I have wiggled and jiggled every wire I could find to see if there is a loose connection issue, but nothing works. It seems to be all of the lamps connected to the "orange" connector on the middle left of the driver board. Is this most likely a board issue?
Thank you for any help anybody can provide.
