I happily inherited Jim's (YodainMN) Qix trimline cab. He said he had been having issues with it so I knew I was walking into a project. I also picked up an untested boardset from someone local. It is complete but had "needs chips" written across the top of the Video Processor pcb. I installed the Arcadeshop switcher kit that Jim had picked up but not installed and changed out the entire pcb set to see what I could get out of it.
So, here's try 1 ("new" boardset):
The game boots up but the entire screen was scrambled. I hit the self test button on the video processor pcb and got the 4th LED to light up so the LEDs were 000100. The manual said this indicates a communication issue with the Data pcb. It recommended that I pull P6 to help isolate the issue but I wasn't sure what that was. I ended up swapping out the Data pcb with the one that was in the cab when I got it from Jim as I was concerned about the connectors on the one I had in there. This leads to "try 2"
Try 2:
The game booted to a black screen with flashing white along the sides. It seemed like it was in some sort of reset loop but wouldn't ever boot up. When I hit the self test button there were no LEDs lit up but I actually got something on the monitor. The first pic below was the first power up with this boardset combination. I wanted to try swapping in the original Video Processor pcb that was in the cab when I picked it up from Jim... which leads to "try 3".
Try 3:
The game booted to the same black screen with flashing white along the sides as I mentioned in Try 2. When I hit the self test button I got what you can see in the 2nd pic below.
At no time during any of these tests could I get any coin up or other sounds. In Try 2 and 3, once the game went to the screens pictured I couldn't do anything to get it out of this screen.
Thoughts?
