OutRun Deluxe Upright - Horizon issue
Hello arcade gurus!
Well, it seems like I'm playing the gopher game here; I make progress on one front, and another problem pops up for me to figure out. I was recently having some sound issues with my OutRun cab (discussed in this thread) which I was able to successfully fix by removing, polishing the pins of, and re-seating all the removable EPROMs on my Rev.B PCB. Huzzah! I get to hear that lovely music in all its pristine glory again.
However, after re-assembling my cabinet I have now run into a NEW issue: the blue levels and vertical position seem to be malfunctioning. See the below photos:
As you can see, the "horizon line" for the blue sky in the background doesn't come down far enough. It still moves up and down as you crest hills or your view shifts downward, and you can still vaguely see the clouds against a white background, but before they were starkly contrasted against the blue sky. There also seems to be an issue with blue levels on the progress map screen as well, and maybe some general coloration issues during various stages.
These were all working perfectly before I pulled out the PCB to clean all the EPROM pins. Here's a video I recorded to demonstrate the now-fixed sound issue:
Now just to answer a couple of anticipated questions: yes, I'm all but certain all of the EPROMs and chips were replaced exactly the way they were when I removed them (with the exception of two which, if you'll read in the other linked thread, were incorrectly seated), as I did them each one at a time. And no, I didn't make any changes to the monitors color/brightness/contrast adjusters. The only thing that was changed was me unhooking all the connectors from the PCB, disassembling the top/bottom pieces, removing-cleaning-replacing all the removable chips, re-assembling the PCB, re-installing it in the cabinet, and re-attaching all the connectors.
I can't seem to find it now, but in the back of my head I remember reading about someone having a very similar (if not exactly the same) problem, but I don't recall what the resolution, if any, was.
Can you guys give me some guidance? I supposed I can disassemble everything and go through the remove/replace of all the EPROMs again, but I don't want to do that if the problem is likely to lie elsewhere.
Thanks much for any help that can be offered!
