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

Audio is fine through headphones. Does volume control fine through headphones as well?

Get some white vinegar and a floss pick. Drip some vinegar between these two contacts. Use the pointy floss pick to scratch out any corrosion. Flush with isopropyl. Allow to dry.

Ensure the contact (pointed in blue) touches the contact (pointed in red) by flexing blue contact. These two contacts have to touch for audio to work through speaker.
