No sound, speakers not showing up in display for any listening modes

Had a week long power outage due to a storm. After power came back, NR5007 does not display speaker icons in digital display on front for any of the listening modes. No sound.
Any ideas?
thanks

Hi JohnC80w,

Have you tried a reset of the unit yet? To do the reset you need to turn the receiver on, then on the front panel of the receiver press and hold the "VCR/DVR" button while doing that press the "STANDBY/ON" button. You will see the word "Clear" in the display screen and the receiver will go into standby mode. PLEASE UNDERSTAND THAT YOU WILL LOSE ALL YOUR AUDIO & VIDEO ASSIGNMENTS ON THE RECEIVER PLUS YOU WILL LOSE ALL YOUR SPEAKER CONFIGURATIONS, SPEAKER DISTANCE AND ALL LEVEL CALIBRATION SETTINGS. YOU WILL ALSO LOSE ANY PROGRAMMED RADIO STATIONS IN MEMORY. Once the receiver goes into standby mode turn it back on and go thru the setup menu for all custom settings. If this does not resolve the issue then I would suggest a service center for further evaluation. Authorized service centers can be found on our main page under support.
