Kenwood P-26 turntable issues

Hi Everyone, recently I’ve found a old Kenwood P-26 Turntable that was apart of an hifi system, Currently i have the turntable hooked up to my Edifier R1000T4 speakers whilst using an behringer pp400 pre amp I’m not sure what is causing the buzzing sound as the turntable includes built in rca cables and dose not have a grounding part.

update: the sound isn’t working coming from the left side would although it works on the there is slight buzzing on the left side when i turn it up would this suggest that the built in rca cables are bad?

any advice would be appreciated
