Had resetting issues (along with occasional sound garbling), did a shotgunning of capacitors and transistors on the power supply, display stopped working (but I know the display functions by swapping it in whirlwind).
So getting a replacement power supply on friday from K's arcade:

I don't trust rottendog, and they said most vendors aren't selling X-pin boards because of issues (only Nitro seems to carry it). Hoping this fixes most of my issues.
On a sidenote, I want to build a bunch of mods for this game since it's my favorite movie trilogy. Seen a bunch of great ideas in various threads (pepsi perfect pingulp, railroad tracks, delorean hooked up to flasher circuit, mini hoverboard, wild gunman paper model). I don't want to just build a bunch of parts and randomly put them on the playfield, I want it to look cohesive and planned out. In general, the left ramp seems to be the western side, and the right seems to be the 2015 side (flying delorean, floating sign). 2 things I want to do right off the bat:
1. Build a 3d printed lighted twin pines sign to cover one of the metal brackets on the back:

2. Replace the clock tower with a 3d printed courthouse mall from 2015:
