I have looked for discreet codes for this model DVD in the past and newer models since. I have not had any success with this.. So the work around is to use the "Play button to send your power on" By hitting play you will not turn the unit off.. Has worked fine for me on all JVC DVD models. Use the "power button" to turn the unit off..

If you have any luck finding discreet codes please let me know,

Good luck!
