try to connect the receiver to a tv via the monitor out from the receiver to the tv. you may be able to see the OSD (on screen display of your settings) change the function on that to turn on the front display. alternatively look on your remote to see if you can turn up the light of the front display.
if these don't work possible that the light of the display has blown.

Turning any receiver off will erase the settings - there is no backup battery (Onkyo uses Battery Free Memory Backup) and the length of time depends on the capacitor charge. Why not just leave the receiver plugged in? Stand-by mode uses a negligible amount of power - enough to keep the capacitors charged and the LED on the front panel on.

The standby light should be on. If it is not, then check the main fuse. WIth the unit unplugged, remmove hte top cover and check the fuse by the line cord. If that is ok, then you will need to check the primary winding on the standby transformer. That transformer has a thermal fuse internally located and that sometimes gets blown due to a power surge. If you do not have the equipment to test this, get a detailed estimate from a local servicer. The standby transformer usually costs arounf $25 or so.

Aux is just a generic label for any unassigned high-level (non-Phono) input. They're all electrically the same as the 'labeled' inputs.
Use any of the following instead (whatever is available and convenient): CD; Tape 1 In; Video 2; Video 1 In - then selct the appropriate function to hear the program.
