mhl/hdmi sudden Issues?

[gary808]

So I got my Samsung galaxy note 10.1 2014 about two weeks ago,
I borrowed my dads mhl cable so I could watch the films I had on it on my tv,
All was good, two days no hassles,
Come to use it yesterday, it's stopped working, tried three different televisions,
Nothing,

Dad's tab 3 works fine, and his s4 on the cable,

Any ideas if I've killed It? Changed a Setting? Or an updates stopped It?

Thanks in advance
