2011 Discovery 4 HSE Mood Lighting

All the mood lights (2 x LEDS on each of the 4 doors) has stopped working along with the backlight of the clock. Tried fuse box but to no avail. Any ideas?

Maybe just the dimmer turned down? All other instrument lights still working? Life in the slow lane

Thanks for the reply, but not the dimmer.

Maybe:
Topix:
"The LED-Ambient components are protected by FETs (Field Effect Transistors) which can detect overloads and short circuits. The FETs respond to heat generated by increased current flow caused by a short circuit. On a normal circuit this would cause the fuse to blow, rendering that component and circuit inoperative. The FETs respond to the heat increase and disconnect the supply to the affected circuit. When the fault is rectified or the FET has cooled, the FET will reset and operate the circuit normally."

The same transistor FET.
