Lights out on LG micro hifi

[sherpa andrew]

I have an LG micro hifi model LF-M340A. Just recently all the lighting on the control panel went out, but everything else works perfectly.
- Backlight and LCD panel not working
- Lights on two control buttons not working but buttons still work
- Fancy rainbow coloured lighing around volume knob not working but volume works.

All fuses are ok. I have pulled off the front panel but can't get the PCB off this panel.

Any ideas?

Thanks.
