CDJ 1000MK3 No lights

Hello all,

Looking for anyone to shed some light on this issue:-

After replacing the main top display board, none of the lights on my deck function. Have tried putting it in service mode, to no avail. (Buttons all function but none light up, apart from Jog wheel and Main display, which still remain visible)

Is there a fuse or circuit which I should be checking? I have a good understanding of electronics and the equipment necessary to do so (Multimeter etc)

I am assuming the problem lies somewhere on the main display which I have just replaced

Please advise!
