Hisense TV Blinking Codes (All Codes Explained)

A Hisense TV flashing a red light is like a distress signal, a cry for help from your beloved entertainment hub.

This blinking isn’t just a random occurrence but a coded message revealing the underlying issue plaguing your TV.

Jim Coleman (a professional TV repair expert) says, “These blinking codes are like a TV’s way of talking to us, telling us what’s wrong under the hood.”

So, understanding these codes is the first step towards resurrecting your Hisense TV.

Let’s move on…

Let’s discuss about the Blinking pattern of a Hisense TV

Hisense TVs communicate through a series of blinks, each pattern signifying a unique problem.

Here are some of the most usual ones:

  • 2 Blinks: This often signals a problem with the power supply or the LED backlight.
  • 3 Blinks: Similar to 2 blinks, but might also indicate a problem with the T-con board, which controls the display.
  • 4 Blinks: Problems with the main logic board, which is essentially the brain of your TV.
  • 5 Blinks: This is a more serious code, often signifying a severe malfunction within the mainboard.
  • 6: These less common codes usually indicate issues with the TV’s firmware or internal software.
  • 10 Blinks: Primarily associated with issues in the inverter board or its wiring, affecting the backlight operation.

Each blink pattern is a clue, guiding us towards the root of the problem. “Think of these blink codes as a treasure map,” says electronics engineer, Sarah Johnson. “Each blink is a step closer to finding the buried treasure, which in this case, is a functioning TV.”

Troubleshooting Steps: A 100% Working Fix

Now that you have a better understanding of the blinking codes, you can now try some basic troubleshooting steps.

Step 1) Do an HDMI Reset

This is not like power cycling.

In power cycling, you just disconnect the TV from the power outlet and then reconnect it again after a specific time.

But in HDMI reset, along with draining power from the TV’s internal components, you also need to address the potential buildup of residual static electricity that interferes with the HDMI signal.

Anyway, here’s how:

  • Disconnect the TV from the power outlet completely.
  • Similarly, disconnect all the other HDMI-connected devices and audio cables from the TV.
  • Wait for 5 minutes.
  • During this time, press and hold the TV’s power button for about 30 seconds.

Once you are done, power the TV back on.

Now check whether the TV powers on correctly. If not, proceed to the next step…

Do this at least 5 times. Sometimes, the first and second attempts don’t work, but the fourth try may be successful. Who knows, this could also be the case for you too?

2) Inspect and Clean Internal Components

Open the TV’s back cover with caution, only if you’re comfortable doing so and have the necessary tools.

A good rule of thumb is to only attempt this step if you’ve previously opened electronic devices. Even a small misstep can cause further damage to your TV.

Once you have access to the internal components, use compressed air to gently remove any dust or debris from the circuit boards, vents, fans, and other components.

Be mindful of the distance between the nozzle and the components, as holding the can too close can dislodge delicate components or cause static shocks.

To wipe away any stubborn dust particles, use a soft brush or microfiber cloth.

Finally, once you’ve finished cleaning the internal components, carefully reattach the back cover and secure it with the screws.

Important safety precautions to remember: Avoid touching any capacitors, wires, or connectors with your bare hands. These components may hold residual electrical charges that can deliver a shock or damage the TV. If you need to disconnect any cables, take note of their location and how they are connected so you can easily put everything back together.

Step 3: Mainboard Inspection and Diagnosis

If the previous troubleshooting steps haven’t resolved the blinking red light, it’s time to turn our attention to the mainboard, the central hub of your Hisense TV’s operations.

But diagnosing mainboard issues requires a delicate touch and a bit of technical know-how.

However, before proceeding, ensure your TV is unplugged and you have the necessary tools to open the back panel safely.

Once you have access to the mainboard, carefully inspect it for any visible signs of damage, such as:

  • Burnt components: Look for any darkened or discolored areas on the board, particularly around capacitors or resistors.
  • Swollen or leaking capacitors: These cylindrical components can sometimes bulge or leak fluid when they fail.
  • Loose or damaged connectors: Check if any cables or connectors are loose, damaged, or disconnected from the mainboard.

If you identify any of these issues, it’s highly likely that the mainboard is the culprit behind the blinking red light.

At this point, you have two options:

  1. Contact Hisense Support: If your TV is still under warranty, contacting Hisense is the best course of action. They can provide further guidance, repair the mainboard, or even replace your TV if necessary.
  2. Seek Professional Repair: If your warranty has expired or you prefer to take matters into your own hands, consider taking your TV to a qualified technician. They have the expertise and tools to diagnose and repair mainboard issues effectively.

This is because, attempting to repair the mainboard yourself can be risky if you don’t have the necessary experience.

A misstep can lead to further damage, potentially rendering your TV irreparable.


Q: Is the blinking red light covered under warranty?

A: If your Hisense TV is still under warranty, the blinking red light issue might be covered.

Contact Hisense customer support to inquire about your warranty status and potential repair or replacement options.

Q: How much does it cost to fix a Hisense TV with a blinking red light?

A: The repair cost depends on the specific cause of the issue and whether your TV is under warranty.

If the problem is minor and can be fixed with a simple reset or cleaning, it might be free.

However, if a component needs replacement, the cost can vary depending on the part and the repair service’s fees.
