To answer your question about the jumper, it's due to one of the final board revisions. This surprises me a bit because the white ones were the final batch. It should have had the latest board revision which didn't require the jumper wire. These were manufactured by Gibson after they bought Oberheim. They may have thrown an old board in, or it may have been transplanted from a black one.
Interesting video - congratulations on the repair. I suspect that another problem that may arise with equipment of this age is the electrolytic capacitors - it is best to preemptively replace all of them so that they do not spill and cause more damage in the future....
Enjoying your vids, but man, you really need a quality solder vacuum. A Hakko is a game changer. It will significantly reduce your stress level removing components
You should have used solder wik that sucks the solder up. That way you could have replaced the LCD's in a flash. even if they where not defective. But you also should have removed all those wires prior to that. to prevent all that damage. These displays almost never fail, it's the wiring or the drivers (IC's)
Loving these videos man!

great vid. Incredible that the buttons work. I find old synths with sticky buttons so often

I agree. In this case I believe both the caps and voltage regulators had been previously replaced by the last owner. But yeah, great advice!
