A shortwave radio I got at a swapmeet

I recently aquired a Grundig satellit 2000 AM/FM/SW/LW radio from a swapmeet, the dials light up, but no sound comes from the speaker. Please tell me what to do to get it working again thank you.

e-mail me at tomp12@msn.com,tomsheridan@netscape.com, and tompsheridant1@aol.com. thank you
