Common problems with audio and video products

  • DVD player won't play discs—If the disc you put into your DVD player won't play or skips around constantly, there are a couple possible causes. The disc could be scratched or dirty, or the lens that the laser uses to read the disc may be scratched or dirty.
  • Amplifier hums—Amplifier humming can be caused by the volume control if the humming changes with volume change. If it remains constant, the problem might be a loose connection or an ungrounded circuit in one of the components.
  • Receiver won't power up—If the receiver won't turn on, the problem could be that the switch is broken, the power cord is unplugged or there's an electrical problem on the circuit board.
  • Speaker is dead—Speaker problems commonly come about from playing music at excessive volumes. Blown-out speakers will have tears in the rubber lining, and/or the electrical connectivity will be interrupted.

Diagnosing Denon stereo malfunctions

If your stereo system isn't putting out any sound, there are a few things to examine. First, make sure that you've selected the right input and speakers on the receiver settings. The instruction manual can help you figure this out. If all the settings are correct, examine all the cords and wires behind the system. Make sure everything is connected properly and that there's no damage or frayed wires. Next, take off the grill and examine the speaker for physical damage. Open up the case and run a 9-volt battery over the leads. If there's no popping sound, the electronic connection has been severed.
