What to do if my Denon Stereo System won't turn on?

If your Denon Stereo System isn't powering on, first, try unplugging the DC jack and plugging it back in to see if the blue LED illuminates. If that doesn't work, it might be due to poor contact of the DC Jack, in which case defective parts should be replaced. Also, try to press and hold the "Bluetooth" and "Connect" buttons on this unit for 5 seconds or more to initialize User Initialization Mode. Finally, make sure that the speaker is connected with a router based on "QUICK SETUP GUIDE."
