Hi everyone

so I bought my first ever record player, a project elemental, a month ago and I love it. But today it developed a strange hissing sounds when you turn it on (it hisses both when the turntable has a record playing or not.

its hooked up to a single speaker which is fine when linked to anything else. I'm not technical at all and have fiddled with it and found that it seems to relate to the left hand white bit of the cable that comes from the player (I have a single cable with two connectors at either end, two hook up to the player, red and white, then the other two are in a single adapter that go in the speaker). When I unhook the left part at either end the hissing stops. 

Any ideas how to solve this? the player was working fine then today when I changed a record it started. I've tried playing different records, but it is still there. And as it hisses when no record is playing and it simply switched on so it doesn't seem to be a record problem more a player problem 

help!!!!
