  Heather OsbornJul 30, 2025
  If there is no sound, several factors could be at play. First, check if the power indicator LED is lit. If not, examine the amplifier fuses, the remote turn-on wire connection, the signal leads, the gain control, and the source volume level. Also, try cleaning the contacts on the fuse holders. If the fault LED is lit, inspect for a speaker short circuit, amplifier overheating, or low voltage.

  If your amplifier isn't turning on, start by checking if there is power to the power wire. Ensure the amplifier has a solid ground connection and repair the power wire or its connections if needed. Next, verify if there's power to the remote turn-on wire when the receiver is on, checking the connections to the +12 V source. Finally, see if a fuse has blown and replace it if necessary.

How to troubleshoot no sound on one channel of my Insignia NS-A1000?
- D
  Don RogersAug 23, 2025
  To troubleshoot the absence of sound on one channel, begin by inspecting the speaker leads for any short circuits or open connections, and repair if needed. Next, check the audio input leads by reversing the left and right inputs to see if the issue originates before the amplifier.
