Its the identical switch, my scope lacks the digital top row.
Can this be fixed? I've tried to looking inside and did some checking,
but can't tell if its switches, relays, or whatever. Does somebody know
what to do?

it would be best to know the exact MO# of the scope,
as far as I know, even with scopes this old, it's done with rudimentary logic functions inside the scope and the switch has little to do with it, other to tell it what mode to go in, even my Tektronix 7934 even though it's from the mid 80s, has very complex logic circuits in it.
