Hinari HIFI unit (Brookhouse LA2)

Probably around 30 to 40 years old - still powers up and plays records & tapes ok BUT no sounds seems to come out of speakers for some reason - you can hear the sound faintly coming from inside the unit, just not the speakers - might be an easy fix if you know what you are doing ? - sadly get an error message when trying to play CDs but maybe something may just need cleaning using an air duster ? - not too sure about the radio due to the speaker issue
