If you have noticed your Hisense TV blinking red light after you hit the power button, do not panic. It indicates that the TV is getting power from the main board but can’t distribute it.
However, this red light blinking is in various progressions. It can blink once, it can blink twice, or maybe thrice. Each number of times it blinks, it has its significance.
Fortunately, I am very knowledgeable when it comes to Hisense TV issues like this. By the end of this guide, I will help you understand what it means when you see your TV blinking red light and how you can fix it.
Why Is Your Hisense TV Red Light Blinking?
There are so many reasons why your Hisense TV is blinking a red light. The blinking red light could either indicate a hardware or software failure. Other reasons your Hisense TV is blinking a red light include;
- Damaged power supplies or cables.
- Outdated firmware.
- Signal issues or HDMI glitches.
Now that you know why your Hisense TV is blinking red light, let’s go into understanding the significance of each blinking pattern.
What does the blinking red light on Hisense TV indicate?
The Hisense TV blinks the red light a specific number of times as an indicator of an error or a problem. This indicator can help anyone trying to fix the TV diagnose the problem.
However, the meaning of the blicking pattern may vary depending on the issue. I’ll explain all the errors that correspond with the number of times the TV blinks.
1. Blinking once:
When your Hisense TV blinks the red light once, it means it’s stuck on standby mode. When this happens your TV screen will go black while the indicator light stays on and even when you press the power button, nothing happens.
2. Blinking twice:
When your Hisense TV starts blinking twice, you should know that the TV is experiencing a Power supply issue. It could be an issue with the amount of voltage supplied to the TV or a faulty power cord.
3. Blinking three times
This indicates an issue with the inverter circuit or backlight. The inverter circuit is what drives the backlight of your Hisense TV and when it’s faulty you might have the TV blinking red light three times
4. Blinking four times:
When your Hisense TV blinks 4 times, it’s an indication that there is an issue with your video processor or main board. This issue can affect the display and overall functionality of your TV.
5. Blinking five times:
If you notice that your Hisesnse TV is blinking red light 5 times, there is a problem with your Timing Controller (T-Con) board. The T-Con board is one of the most important components of your Hisense TV. It helps in processing video signals and controlling the timing of the individual pixels on the screen.
6. Blinking six times
Your Hisense TV will blink six times when there is an internal temperature sensor or cooling system issue. This issue can lead to overheating which can potentially damage the TV.
7. Blinking seven or eight times
Hisense TV blinking seven times is often accompanied by a black screen. This indicates that there is an issue with the backlight of the TV.
8. Blinking nine times
A backlight voltage issue is often the reason why Hisense TV blinks nine times. If there is a problem with the voltage supply to the backlighting system, you will get the blinking red light accompanied by other issues like dim or black screen, uneven brightness, flickering screen, and backlight bleeding.
9. Blinking ten times
Finally, If the red light on your Hisense TV is blinking ten times, it’s either due to a faulty motherboard or LED driver/stripes.

To update your Hisense TV, follow the steps below:

Method 4: Restore the TV’s factory settings

- Inspect the power cord for any damage and make sure it is perfectly plugged into the TV
- Plug the TV in a different power outlet and check if the red light continues to blink

You should also contact Hisense TV support for further assistance. If the TV is still under warranty, they will help you fix the issue free of charge or even change the TV set if necessary.
