Assuming your stylus is OK, remove stylus and check if there's gunk where stylus connects to the magnets and clean it with alcohol. You can also dip your cartridge in alcohol bath.
I use microscope to ID the shape of stylus or you can download magnifier software onto your smart phone if you have one and visualize stylus tip wear. If it's dull, guess, it will sound dull and will need be replaced.
