Insignia TV red light blinking – how to fix and possible causes

One of the reasons why your Insignia TV has a blinking red light is because of power supply issues. The quickest way to try and fix it by performing a power cycle.

Here’s how you can do a power cycle –

• Switch off your TV
• Unplug it from the main outlet
• Wait for about 60 seconds
• Plug it back in and switch the TV on
• Check if the blinking red light is gone

Sometimes a loose or broken cable can cause the red light blinking on your Insignia TV. To make sure this isn’t the case:

• Check each wire and look for any cuts or lose ends.
• Check if the external devices are properly plugged in
• If you see any damaged cables, consider replacing them

Some gaming consoles have a feature called INlink that won’t turn on your TV unless the console has been turned on.

This can mean that there was nothing wrong with your TV. We’d advise you to turn off the feature.

• Go to the setting of your TV using the remote
• Select to INlink (HDMI-CEC) or Control other devices (CEC)
• Make sure it has been turned off.

If you have any console connected, try turning on the console to turn on your TV. You can also disconnect the console entirely from the HDMI port and then switch on your TV to check if it is working.

As mentioned earlier, your Insignia TV can flash the red light if there’s a power supply issue. One of the things that might cause hindrances in power supply is the outlet itself. Or the surge protector if you have one.

Here’s what you can do –

• See if your power outlet is working properly. You can check this plugging in another device
• As mentioned earlier, you can perform a power cycle and see if that solves your issue
• If you have a surge protector, try removing it and plugging the TV directly to the wall outlet

There is a possibility that your TV is functioning but your remote isn’t, which can cause the red light to blink.

If you suspect that this is the case, here’s what you can do –

• Get closer to the TV and see if it responds to the remote
• Change the remote batteries, if you think it has run out of juice
• If your remote does not work, you can get a universal remote or use a remote app

If your TV’s software is old, then it might have some performance issues.

While the exact process might be different for your model, here’re the common steps to follow-

• From the home screen, go to Settings menu
• Go to Device Preferences or similar option
• In the About section, look for System Update
• The TV will look for available updates
• If the updates are available, install them

After your TV restarts, see if the red blinking light is gone.

If nothing seems to work, then you can consider factory resetting your Insignia TV. Usually, a factory reset resolves TV issues.

Before you do a hard reset, keep in mind that your data might get wiped off – so you should use this as a last resort.

Here’s a general rundown of the resetting process –

• Go to Settings menu from the Home screen
• Look for the Advanced Settings option
• Then, search for Reset or Factory reset option

After your TV restarts, check if the blinking light is gone.

Sometimes, there might be damaged hardware in your TV such as broken backlight strips, swollen capacitors, power board failure, etc. that may cause the blinking light. In that case, contact a professional from the Insignia help center. You may need details such as the model of the TV, purchase date and contact info for their assistance.
