My BK has begun having strange issues, it is getting old, maybe it's pinball senility?

If I leave the machine on for a bit, it starts playing the attract sound / background sound continuously, even though I have that disabled in the settings.

If I start a game, at first the sounds will be correct, but after a bit it will start playing the wrong sounds for different events. Like, it will play the tilt sound for the slingshots. Basically all the sounds will be wrong eventually, but the game continues to play fine all the while.

Was thinking maybe a memory problem, or possibly it could use some new capacitors on sound board as it also developers a background hum that gets louder the longer the machine is on (heats up).

Any advice is appreciated!

Bump..

Nobody's ever had this happen before?

I think I solved it by reseating the connectors and pressing down on any socketed chips on the sound board.
