Front Panel LCD is OFF

Just received my warranty replacement PR4100 and after the first reboot, my front panel LCD stop working. It is OFF and I do not know how to turn it ON again. I tried the ON and OFF LCD switch under the setting but no success. Can someone help me bringing back my LCD back to life ? Thanks
