TD Sol spinning reel from mid 2000s anti reverse

[Warscott]

I have TD Sols that the anti reverse quit working.  I sent them off to be repaired to a new to me repairman and the repair shop said they replaced the anti reverse bearing or clutch. When I got them back, the anti reverse still doesn't work.  Reel handle just randomly goes backwards.  I have no interest in shipping them back again.  Is there something else that would prevent this from working properly?  Thank you.

Maybe the AR lever or AR cam spring? Try manually holding the AR lever to the engaged position while spinning handle to see if it holds. Thinking maybe the cam spring is weak, or lever shaft is worn, but I'm no expert. Hopefully a Daiwa spinning reel expert on here can give more insight.
