Why is the picture quality on my Insignia NS-40D40SNA14 TV good on some channels and poor on others?
- M
  Michael MarquezAug 31, 2025
  If your Insignia TV shows poor picture quality on some channels but good quality on others and the sound is good, the problem may be a weak signal from the broadcaster or cable TV provider. If you connect to cable or satellite TV without a set-top box, you may need to install a set-top box to improve signal reception and picture quality. Contact your cable or satellite TV provider about upgrading to a set-top box.

  If your Insignia TV has no power, ensure the power cord is correctly connected to the TV and the power outlet. If it's connected, 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, so try turning off one device at a time to determine which one is causing the interference, then move it further away from the TV.

Why is the picture dark on my Insignia TV but the sound is good?
- J
  James PetersenAug 28, 2025
  If your Insignia TV displays a dark, poor, or no picture but the sound is good, try switching to another channel as the station may be experiencing problems. Also, ensure that the antenna or cable TV is connected correctly and securely. Adjust the brightness and make sure that the correct picture mode is selected. If you are using an antenna, the digital channel signal may be low. If the signal strength is low, adjust the antenna or use a highly directional outdoor antenna or set-top antenna with a built-in amplifier. Make sure that the video cables are connected securely to your TV and if the video cables are bad, try a new set.

  If your Insignia TV displays no picture and no sound, try the following: First, press the power button on the TV or remote. Ensure the Audio Only option is set to Off. Check that all video cables are securely connected. Adjust the contrast and brightness settings. Make sure the power cord is plugged in, the correct video input source is selected, and try another channel in case the station is experiencing issues. Confirm the incoming signal is compatible, and that the antenna or cable TV is properly connected. Finally, check the closed caption settings, as some TEXT modes can block the screen.

  Christina GuerreroAug 27, 2025
  If your Insignia TV has good picture but no sound, first increase the volume and make sure the sound isn't muted. Ensure headphones are disconnected, as they disable the TV speakers. Verify the correct audio mode is selected and that all audio cables are securely connected. Also, confirm that your antenna or cable TV is properly connected. If using an antenna, check the digital channel signal strength. A bad audio cable may also be the cause, so try a new set.

  Joshua SkinnerAug 25, 2025
  If your Insignia TV remote isn't working, ensure the power cord is correctly connected to the TV and a power outlet. Also, make sure there are no obstructions between the remote and the TV's sensor. Point the remote directly at the sensor, verify the batteries are correctly installed, and replace dead batteries with new ones.
