Basic home theater and stereo troubleshooting tips.

  • It seems a number of people are experiencing problems with the HDMI in the new receivers.
  • If you have experienced any of these issues most likely you have a bad HDMI board. Troubleshooting: Connect HDMI Cable directly from the DVD or Cable box to TV bypassing the HDMI on the audio receiver and see if it works.
  • If you have lights on your Receiver but no sound Check Tape Monitor switch.
  • If you are using Master Remote for your Home Theater be sure all units are off before you turn it on.
  • Verify if Receiver is on right input for audio and video.
  • Verify if Receiver/Amplifier is set on right speakers output and use correct speaker and wires see below.
  • Turn off your Receiver or Amplifier before inspecting speaker connections.
  • Check Speaker Wires on Receiver and Speakers look for damage or loose connections and whiskers.
  • Make sure that the insulation is adequately stripped on both ends of the wires and they are not touching each other and not damage receiver.
