I've been able to sort out my LCD upgrade, it turns out that the controller was sold with the incorrect wire (mine had about half wires in the connection that goes to the screen for some reason). I'd like to thank Kaneda, ripple, and jbigdoggf for their help walking me through the process and answering questions I had. It's great that the pinball community supports one another. The screen is installed, working and looks great!
I also have two key quality of life adjustments I discovered today and strongly recommend:
1. Spooky's inner orbit adjustment of removing the screws has fixed the shot so it's loopable and reliably hit - the curve works. Given this, I recommend lowering the ballguide at the screw closest to the player as far as possible. This will achieve 3 things:
a. It exposes the rubber post for right orbit shots that return to the inner orbit (reverse), the ball hits the rubber and lofts it right above the upper right flipper. When the post is hidden out of the trajectory of the ball, the ball returns just below the Meeseeks target (which is less fun).
b. With fewer screws, the ballguide may be at risk of shifting. This will prevent the centrifugal force from shifting the wall over time and scratching the playfield
c. It doesn't negatively affect the loopeability, if anything it makes the shot easier.
2. Adjust the amplifier to reduce glass vibration noise - The amplifier is on the right side of the pin about a foot an a half in. The knobs can be turned to change the settings (they should be on the side facing the wall). There are five knobs to turn (from closest to furthest), Sub Volume, X-Over (these first two are smaller), Treble, Bass, and Volume Control.
Some may zero in on turning down the base to reduce the vibration, but this isn't what I recommend. Sub Volume is what you want to focus on - this is the amount of subwoofer volume relative to the rest of the volume... But it might as well be called the "Glass rattle level". Turn it all the way counter clockwise, then slightly increase. If no rattle, increase a bit more, until you hit the sweet spot. Mine is just a nudge over all the way counter clockwise.
Hope this is helpful.
