Does the sound work when you plug in headphones?
Hardware wise, you should use some 96° isopropyl alcohol and clean the volume lever and speakers.
If the problem persists, open it up and carefully look for corrosion, and clean it with alcohol and a toothbrush. Also check for broken connections or cables that aren't plugged in
