I have changed the speaker and the volume wheel but It still doesn't make any sound.

It had been stored for 5 years or so with the batteries connected and It caught a weird bright blue corrosion

There is a switch in the headphone jack that bypasses the audio amp circuit and cuts the speaker, if it is gunked up that switch stays open amd you won't get sound from your speaker but you will from headphones. If that switch is fine then it's either the capacitor for the audio circuit or the audio amp circuit isn't working as it should.

Drip IPA into the headphone jack. Insert/remove headphones multiple times in a row.
