I would test the switches on the line before throwing a $400 board at it. Might just be a bad diode on a switch.

Quoted from Cheddar:this board looks pretty jacked and hacked. The last pic you shared is the switched solenoid section and has nothing to do with your switch matrix so repairs there will do nothing about the red saucer. Here are the parts that look hacked in that last pic

C47 which looks to be exploded on your board is part of the display circuitry? see here: [quoted image]
meanwhile I see stuff like this and I don't trust this board:

If its working, isolate the switch problem first.
Would be unfortunate to spend $400 for a board, still not fix the problem which turns out to be a .20 cent diode.
Quoted from M0t10n:What is the best way to test the switches? Visually they all looked connected but you’re right it could be just a diode failed.
Diode failing is common enough I keep 50+ on hand and just replace even if I think one is bad. Not uncommon for them to fail at all.
Quoted from Cheddar:a missing switch diode won't cause any damage but prevents the column from passing on to downstream switches. you do need a diode there
Make sure there isn't a diode on the underside of the playfield, DE did that over the years.
