The first step is to completely discharge the power of the Insignia TV by disconnecting the cable from the back of the TV as well as from the wall outlet.

The next step is to verify that the outlet is functional by plugging another device such as a lamp or phone charger into the strip or outlet.

Inspect the TV’s Power Equipment:

The Insignia TV’s power equipment could be a standalone power cable or a combination of a cable and a power brick.

You need to verify that the cable is not broken, burnt, or melted on its connectors, which ultimately prevents the TV from being supplied with an electrical current.

Was There a Recent Power Outage?

If you’re able to recall a recent power outage, keep in mind that the red light might be appearing due to fluctuations in the power.

The Insignia TV might remain blinking in red until the power is fully back and there are no fluctuations or any sort of inconsistency.

Pro Tip: Plug the TV directly into the electrical outlet without having any strip, power plug, or anything in between the outlet and power adapter. 

2. Inspect the Insignia Remote!

One of the reasons why the Insignia TV is blinking in red is false signals from the remote.

Well, whenever one of the remote buttons is stuck, it will constantly send false IR signals to the TV, which ultimately makes the IR receiver blink every time an infrared signal is sent.

  • To exclude this possibility, eject the batteries from the remote control!

In case the blinking stops when the remote is without batteries, verify that there is no button that is stuck within the remote.

The easiest way to check is to press all remote buttons, which will also contribute to a full remote discharge, and hopefully, the blinking red light will be finally gone!

Quick Fact: A weak battery charge on the remote might interfere with the IR receiver on the TV!

3. Reduce the TV Overheating

After a force shutdown, the red light is likely to start blinking as an indication that something went wrong.

Here are some of the best steps to help you reduce TV overheating:

  1. Open a window to ventilate the environment/room.
  2. Using a vacuum cleaner removes dust accumulation.
  3. Clean the ventilation openings on the TV from dust.
  4. Lower the streaming resolution to reduce utilization.
  5. Leave the television unplugged for longer to cool down.

In case the Insignia TV is not turning on at all, only the red light keeps blinking, well, now is the time to test plugging your TV into a different power outlet.

Perhaps your wall outlet went faulty and is no longer supplying constant electrical current, which prevents the TV from working…

4. Switch HDMI & Source Resolution!

Sometimes, when you switch to an empty or non-working HDMI input on your Insignia TV, the red light will blink as an indication.

This is why if you have a connected HDMI device to the TV and the red light is constantly blinking, plug the device into an alternative HDMI TV port.

  • The Insignia TVs should have up to 3 x HDMI (1 x SIDE and 2 x BACK ports)!

We strongly recommend plugging your HDMI device into one of the back ports on your Insignia TV since the SIDE HDMI could be worn out.

The back ports are not that frequently used so it’s likely that they will be working better with your HDMI device.

An Incompatible HDMI Resolution?

The Insignia TV red light might be blinking when you’re on one of the HDMI inputs because the connected device resolution is incompatible.

So, switch to another resolution, preferably to a resolution that your TV supports, so try 1920 x 1080 (FULL HD), or 1280 x 720 (HD).

5. Factory Reset the Insignia TV
