Man, I'm confused and not sure what to do next.
Started with a (mostly) working TX Sector that had acid damage on the MPU which caused a few oddities like no multiball. Tore the game down to do a full shop job, completed all ground mods (did all of em at the transformer, and all of em in the backbox on each board), reflowed solder on power supply in backbox and put in a brand new working pot for +5v, put it back together and now it won't boot.
-Splurged and bought a new Swemmer MPU with TX ROMS. Still won't boot. Just a blank screen with half of the playfield lights on
-Threw in a known working driver board from my Robo-War: still won't boot.
-Threw in a known working MPU harness from RW: still won't boot
-Threw in a known working Aux Power Board from RW: still won't boot
All fuses are good. Power at MPU read 5.05v, power at driver board reads 4.87v. I'm stumped.
Do I need to start repinning all the connectors? Should I check voltages somewhere else?
