Why do some channels not display on my Insignia LED TV?
- D
  Donald HoldenSep 12, 2025
  If one or more channels do not display on your Insignia LED TV, make sure that the channels are not blocked. Make sure that the channels are not hidden. If you are using a cable or satellite box, use the remote that came with that box to change channels. Press INPUT and make sure that you have selected the correct input for the device or service you are trying to use. If you are using an antenna, the digital channel signal may be low.

  If, after an Auto Channel Search, there are no channels on your Insignia LED TV, reception can vary by channel depending on the broadcast power level of a given station. Contact your cable or satellite TV provider. Make sure that the antenna or cable/satellite TV is connected securely to your TV. Try replacing the cable between the antenna/cable or cable/satellite box and your TV.

  Michael PowellSep 9, 2025
  If your Insignia LED TV has no power, make sure that the power cord is plugged into a working outlet. Unplug the power cord, wait 60 seconds, then plug it back in and turn on your TV. Other devices may be interfering with your TV. Try turning off one device at a time to determine which device is causing interference, then move it further from the TV.

  samuelnealSep 8, 2025
  If your Insignia LED TV has no picture (screen is not lit) and no sound, press the power button on the TV or remote control. Ensure the Audio Only option is set to Off. Verify that the video cables are correctly and securely connected. Adjust the contrast and brightness. Make sure the power cord is plugged into a working outlet. Press INPUT and select the correct video input source. Try another channel, as the station may be experiencing problems. Ensure the incoming signal is compatible. Check that the antenna or cable TV is correctly and securely connected. Check the closed caption settings, as some TEXT modes can block the screen.

Why is there good picture but no sound on my Insignia LED TV?
- M
  Michael CannonSep 7, 2025
  If your Insignia LED TV has good picture but no sound, first increase the volume and make sure that the sound is not muted. Check if headphones are connected, as this will disable the TV speakers. Try changing the audio mode by pressing AUDIO. If you're using a home theater system, sound bar, or external speakers, ensure they are turned on, not muted, and set to the correct output mode. If connected with a digital optical cable, set the Digital Audio/SPDIF option on the Audio menu to PCM. Also, check that the audio cables and the antenna or cable TV are securely connected. If you're using an antenna, check the digital channel signal strength. Try a new set of audio cables in case the current ones are faulty.
