Quoted from Oldschool77:

The MPU has some very light acid damage on the two PIA chips below the holder

Need to be replaced.

Post a picture of the whole board. Sometimes board is much worse than you may first inspect it.

SCR2 and U51 also look to been hit as well. U43 and the surrounding parts look very suspect as well.

You need to replace the parts that have battery corrosion on the legs. Surely, it has entered inside some of the parts already.

I never worry about that until I replaced the damaged parts. You may be worried for no reason. I have no doubt the issues will clear up.
