How to Fix Hisense TV Flashing Red Light

Hisense TVs offer impressive picture quality so that you can enjoy a movie, your favorite series, or even play games. However, like any electronic device, they can occasionally encounter issues. One such common problem is the Hisense TV flashing a red light. This can be frustrating and concerning, but don’t worry; we have you covered.

A flashing red light on the TV is more than just an annoyance; it signals that something is wrong with the device. It can disrupt your viewing experience and make you worry about potentially costly repairs. However, understanding the root causes and knowing the right troubleshooting steps can save you time.

Today, we will help you understand the causes behind the red light blinking on your Hisense TV and provide you with effective solutions to fix it.

Why is Hisense TV Flashing Red Light?

The reasons why a smart TV flashes a red light include power supply issues, damaged cables, hardware issues, etc. However, in the case of Hisense TV, it can differentiate what the problem is by looking at the number of blinks.

  • Usually, if the red light blinks once on Hisense TV, it indicates that your TV is stuck in standby mode.
  • Two blinks tell us there is an issue with the power supply, and three red light blinks indicate you have an inverter circuit or backlight issue.
  • Four blinks suggest a problem with the video processing board or main board, while five blinks indicate a problem with the T-CON (timing controller) board.
  • If the red light is blinking six times, it gives us a signal for an issue with the internal temperature sensor or cooling system.
  • On the other hand, seven or eight blinks indicate a backlight issue and the nine red blinks indicate a backlight voltage issue.
  • Lastly, ten blinks mean you’ve got a faulty powerboard, mainboard, or LED driver/LED strips.

While finding the reason behind the red light flash issue is very easy thanks to Hisense’s indicator codes, it does not work for all the models, as many users mention that some of the TV models do not follow the number of blinks pattern to indicate the specific issue.

That’s said, the best thing you can do to figure out what’s wrong and fix it is to try all the common fixes one by one to see which one works for you. Read on to check them out.

Get Out of Standby Mode

If your TV is stuck in standby mode, you can simply fix the issue by pressing the Power button to power the Hisense TV on to take it out of standby mode. If this does not fix the issue, move on to the next one.

Get Out of Standby Mode

Soft Reset the TV

The next thing you can try is to soft-reset your Hisense TV. You can also use this method if you having an unstable voltage supply. Here’s how you can soft reset the TV.

Step 1: Power off and unplug the TV from the power outlet.

Soft Reset the TV

Step 2: Wait for about 1 minute, then plug it again.

Step 3: Turn on the TV, and your issue should be fixed.

Update the TV Firmware

If the Hisense TV is outdated, then it may cause some issues, including the red light flash. In this case, you can try updating the device by following these simple steps:

Step 1: Navigate to Settings > Device Preferences.

Step 2: Choose About, then System Update.

Update the TV Firmware

Step 3: If there is an update available, install it.

Once done, see if the issue is fixed or not. If not, move on to the next solution.

Check the HDMI cable

HDMI cable is an important part of a TV, and the same goes for Hisense TV. If there is any damage to the cable or if it’s not connected to the TV properly, it may blink a red light. Here’s what you need to do:

  • Check the cable for any cuts and bends.
  • Verify if the HDMI cable is properly inserted into the port.

Factory Reset the TV

If the above methods do not fix the issue, then you need to try factory resetting the device, as it removes all the software errors and configurations on the Hisense TV. But it will also erase all the data and information stored on the TV, so keep that in mind before performing a reset. If you are okay with that, check out our dedicated guide to perform a factory reset.

Contact Hisense Support

If none of the above-mentioned methods helped you fix the issue, then it means your TV has an issue due to an inverter circuit, backlight, T-CON (timing controller) board, internal temperature sensor, cooling system, backlight voltage, faulty powerboard, mainboard, or LED driver/LED strips.

In this case, you may need some professional help. You can get it by contacting the Hisense support team.

Wrapping Up

So, these are some troubleshooting methods you can try to resolve the red light blinking issue. In most cases, you don’t have to worry when your Hisense TV blinks a red light, as it can be solved by a soft reset, power cycle, update, factory, or even restart.

However, if there is an issue that you can’t fix yourself, you need to contact an experienced technician. You can also contact Hisense for troubleshooting or repair if your TV has an active warranty.
