You have to measure and comment on the results.

Comment if the tuning level function works, since one of the 2 is double-function "tuning meter" if it does not work either, check if the instruments are well, internal coils although it is quite rare, greetings

That is what I think I understand that they are cleaned or lubricated I do not know whether to disassemble them. Because the two are nailed and do not move the center of Chanel FM just moves but does not adjust.

the needles may be magnetized or with static the plastic, try to pass a wet cloth to discard the latter

do not disassemble or lubricate, from personal experience this is not advisable, almost always end up ruining, if the instruments become bad, it is better to do some watchmaker than before and worked with watches, greetings

Check the function selector. The image is of a fisher RS 1052L.

Check the selector and it is well it has continuity, it is more clean with clean contacts. I do not know what the problem might be
