DJM-350 Channel - Master LED

Hiya, Love the pioneer gear best i've ever used!

Now my issue is that when i first got the mixer, the master and channel LED worked fine, displaying the orange red and green accurately.

But recently, it's been going a bit haywire. Only just one little bar of the green on both the two channels, and the master.

I'm just wondering if there's something wrong with the hardware, or my setup is a bit in the poo.

THANKS! :)
