Wharfedale Ipod Micro System IS73 Docking Station partially working

PARTIALLY WORKING. when you turn it on sometimes the screen is a little darker and no sound plays. sometimes there is a little pop through the subwoofer and the screen goes to full brightness and it works as usual. please see the pictures for evidence of what I am talking about. very hit or miss if it will work so it needs attention, could be an easy fix but I am not sure. when it is functional cd player, iPod dock, subwoofer and speakers all work as usual. I do have the remote which also works but I have misplaced it so will send it if and when I find it.
