Insignia TV Won’t Turn on/No Sound/Picture/Flashing

I’ve had my Insignia Smart TV for a few years and one day it wouldn’t turn on. So, I did a bunch of research into how to fix it and here’s what I found.

Attempt to power reset your Insignia TV by unplugging it at the wall. After it is unplugged, hold down the power button on your Insignia TV for 60 seconds. That will completely drain any remaining electricity in the TV. After that plug it back in and attempt to power it on.

If that doesn’t work there are a few other steps you can try to get it working again. However, in some cases the power board or another component has become faulty.

In this article, I will explain the steps you can try to get your Insignia TV to turn on, as well as, explain how to fix other issues that can happen with your Insignia TV.

Insignia TV Won’t Turn On

You instantly know that there’s an issue with your Insignia TV if you can’t get it to turn on. On top of doing a power reset using the instructions above here’s how you can get it working again.

Start by resetting your Insignia remote control. To do that take the batteries out of the remote. Then hold down the power button on the remote for 15 seconds. Finally put the batteries back into your remote and press the power button to attempt to turn your Insignia TV on.

If that doesn’t work then you should try plugging your Insignia TV into a different wall outlet. Or try a different device on the power outlet. For example, you could try unplugging your Insignia TV from the wall outlet. And plug in a smartphone charger and see if it will charge your phone.

If it can charge your phone the wall outlet is working fine, it’s likely an issue with the internal components in your TV. There is typically a pamphlet with the warranty information for your TV. I would contact the customer support for Insignia TVs and enquire about the cost and process for having it repaired under warranty.

It might end up being worthwhile buying a whole new TV depending on the cost of the repair. However, the customer service reps should be able to advise you on the best course of action depending on how old your TV is, and their estimate for how much it will cost to repair.

Insignia TV Has No Sound

Another issue that can happen with your Insignia TV is that you don’t get any sound. This can be because of a range of reasons, here’s what they are.

Plug in a pair of headphones or pair bluetooth speakers to your Insignia TV. Then assess whether sound is audible through the headphones or the bluetooth speakers. When you can get sound it indicates the speakers on your Insignia TV are faulty. It can be repaired, replaced, or a bluetooth speaker can be used.

If you want to repair it, then it’s best to contact Insignia customer support by emailing them. But, there are a few other ways to get it working again that you should try first.

The HDMI cable may be causing the issue. An HDMI cable sends both the picture and the sound from your streaming device, or receiver.

Therefore, if it’s faulty you may get a picture and no sound. If you have a spare HDMI cable lying around, swap it out to see if the HDMI cable is faulty. Otherwise they are very inexpensive on Amazon.

Failing that you can try to power reset your Insignia TV by unplugging it at the wall for 60 seconds. While it’s unplugged hold down the power button on your Insignia TV to drain any remaining power from your Insignia TV.

After that, plug it back in again. Whether that works your next step should then be to contact the customer support team as Insignia, and read through your warranty card to see what is and isn’t covered by the warranty. And whether your Insignia TV is still within its warranty period.

Insignia TV Has No Picture

Your Insignia TV may show a red or blue light that shows that it has power. But, when you turn it on nothing shows on the screen. To get it working again here’s what you should do…

Verify that the Insignia TV is on the correct video source. For example, if there is an HDMI cable plugged in make sure the Insignia TV is set to HDMI1 or HDMI2 depending on what port it is plugged into. It can also indicate a faulty HDMI cable or faulty LED strips.

LED strips can be repaired at a cost of around $70, and people claim that is a very common issue with these TVs. However, it is impossible to know if that is exactly what’s causing the issue.

So, a good first step is to unplug the HDMI cable and then plug it back in again. Sometimes the HDMI cable can be slightly loose. As a result, it sends the sound signal but not the image signal.

Also using your Insignia remote change the source to a different HDMI source to see if it starts to show anything on the screen. If that doesn’t get the picture showing them swap out your current HDMI cable for another HDMI cable. You may have a spare one or you can pick one up on Amazon for under $10.

Before you do that though, reset your Insignia TV. To do that, unplug your Insignia TV at the wall and wait for 60 seconds. After that plug it back in and turn it back on.

If you tried all of the steps above then your Insignia TV is likely faulty and you should contact Insignia customer support to inquire about whether it’s covered by warranty and the cost of repair.

Insignia TV Flashing

An issue that you may have run into is that the screen on your Insignia TV flickers on and off. I looked into how to fix it. Here’s what I found.

Reset the Insignia TV by unplugging it at the wall. Wait for 1 minute and then plug it back in. Power the Insignia TV back on. Verify whether the issue is resolved. Otherwise check the cables and the inputs. Finally, if it is still flashing contact Insignia customer support.

One of the cables may be a bit loose, so any cables that you can unplug you should do so, and then plug them back in. Ensuring they’re pushed in all the way.

If you tried the above steps the official support team from Insignia has stated to get in touch with them to let them know about the issue and they will let you know the best next step.

Insignia TV Flashing Blue Light

If your Insignia TV is exhibiting a flashing blue light, a common cause is a power supply issue. Try unplugging the TV from the power outlet, waiting for a few minutes, and then plugging it back in. Often, a simple power cycle can rectify power-related glitches and reset the TV’s functions.

Another reason for a flashing blue light on an Insignia TV might be related to an input source issue. Ensure the TV’s input source matches the connected device. For example, if you’re using an HDMI connection, ensure the TV is set to the correct HDMI input. If you’re using a remote, the ‘Input’ or ‘Source’ button can help cycle through available inputs.

Additionally, faulty internal components, such as a malfunctioning main board or backlight, can cause the flashing blue light symptom. If basic troubleshooting steps don’t resolve the issue, it may be necessary to seek professional repair. Consider reaching out to Insignia customer support or a certified technician for further assistance.

Insignia TV Black Screen Blue Light Blinking

If your Insignia TV displays a black screen with a blinking blue light, it often indicates a failed firmware update. Try performing a hard reset: unplug the TV from the power source, wait a few minutes, then plug it back in and power it on. This can clear any temporary software glitches or failed update remnants.

Another potential reason for the black screen and blinking blue light on an Insignia TV is related to its mainboard or power board malfunctioning. Over time, these components might experience issues due to wear and tear or power surges. If the TV is still under warranty, reach out to the manufacturer or the place of purchase for a potential repair or replacement.

Furthermore, incorrect source selection can sometimes lead to a black screen. Although the blue light blinking might suggest a deeper problem, it’s still worth ensuring you’re on the correct input source. Use the TV’s remote to cycle through available input sources or try reconnecting any attached external devices, such as gaming consoles or streaming devices, to ensure they’re functioning correctly and transmitting data to the TV.
