Insignia TVs from Best Buy are reputable for their good performance and lower prices. While they are good quality TVs that can be perfect for your home entertainment, sometimes the TV set can have issues, either to do with installation and setup or just one of those days the TV decides to “act up”.

  1. Press the “Menu” button on your Insignia remote control.
  2. Scroll to the right and select “Channels”.

If there is still no picture, try resetting your TV to resolve the issue:

  • Unplug the TV for at least a minute.
  • While it is unplugged, disconnect all the devices from the TV.

How Do I Navigate My Insignia TV without the Remote?

The Roku app will allow you to use a smartphone or tablet to control your Insignia smart TV. However, make sure that your smartphone and Roku player are connected to the same Wi-Fi network:

  1. Download and install the Roku app.
  2. Open the app and follow the on-screen instructions.
  3. Tap on “Devices”.
  4. Select your Roku device.
  5. Tap the “Remote” icon.
  6. You can now use the remote on the app to control your TV.

How to Connect Insignia TV to My Sound System

If you have a sound system that you want to connect to your Insignia TV:

  1. Locate the audio output on the backside of the Insignia TV.
  2. Plug the red and white audio RCA cables into the audio out ports. Make sure the appropriate colors of the cables are connected to the same colors as the ports.
  3. Plug the other end of the cables into the audio-in port on the sound system.
  4. Power on the TV and the surround system. If you are using a surround sound receiver, press the “TV” button on the speaker system. For a stereo system press the “Aux” button.
  5. Adjust the volume using the volume dial or with the remote control included with the speaker system.

If your sound system has an Optical port, you can opt to use this instead of RCA as the sound quality is better and it can support surround sound (5.1)

You can also opt to use an HDMI ARC connection to manage all the sound between your sound system and the TV. This gives you better sound quality like the optical cable and also supports other surround formats like Dolby Atmos.

Why Won’t My Insignia TV Connect to WiFi

If you have an Insignia Roku TV and it is not connecting to Wi-Fi, it may be because the Roku version is outdated. You need to ensure that the latest Roku version is installed.

Navigate to Settings> System> System Update, and then select “Check Now”.  After making sure the lasts Roku version has been installed, attempt to connect to the Wi-Fi network once again.

If the problem persists, go ahead and change the default Wi-Fi network channel throughout your Wi-Fi settings, and then try connecting again.

If your TV is still not connecting to Wi-Fi, then power cycling the TV may solve the problem:

  • Unplug the power cord from the back of your TV.
  • Disconnect the cables between the TV and any connected device.
  • Allow the TV to sit unplugged for 1-2 minutes.
  • Plug back in the TV’s power cord, reconnect any other devices, and then turn them back on.

If power cycling fails to resolve the problem, try resetting your Insignia TV to factory settings.

Insignia TV Input is Blocked Meaning

This is usually an issue of parental controls. If parental controls are on, it can cause the input to be blocked.

To disable the “Input Blocked” feature on an Insignia TV, follow these instructions:

  1. From the Insignia remote press “Menu”
  2. Go to “Setup” and then “Parental”
  3. Enter the password. If you have never set a password previously, enter ‘0000’. In case it prompts for a password change, choose something that will be easy to remember.
  4. Navigate to “Input Block”.
  5. If it is blocked, select and unlock it.
  6. Press “Exit”.

Insignia TV Won’t Turn On, Red Light Flashing

The number of red light blinks is a “blink” code that indicates the nature of the fault with the TV. Usually, these are various failures to do with internal fuses or circuit boards.

If your Insignia TV doesn’t turn on and red light is flashing, it likely indicates a failed main power supply.

There are at least two supplies; one keeping the remote function alive continuously and another that is turned on when the TV is ordered to operate.

To resolve this problem, try performing a power reset:

  • Unplug the TV from the outlet.
  • Then hold down the power button for one minute.
  • Release the power button, plug the TV back into the power outlet, and try to power on.

If a power reset doesn’t solve the problem, you may have to find a technician to fix the problem as it may be much more complicated than you can handle.
