Hisense TV Red Light Blinks 3 Times (Here’s The FIX!) in 2024

Flashing red light on Hisense TVs are often an indication of error, whether from software or hardware, as it is with most TVs. The number of times the light blinks gives an indication of the specific error based on the blinking codes.

If your Hisense TV red light blinks 3 times, and won’t turn on, then you are not alone.

In this guide, I am going to explain to you why this happens and more importantly, show you how to stop this error on your Hisense TV, whether it happened while already watching TV or just when you try to power it on.

Without any further ado, let’s dive right in!

Why Hisense TV Red Light Blinks 3 Times

If your Hisense TV red light flashes 3 times when you try to power it on and there is no picture on the screen, then you most likely have a LED rail shutdown issue. In such case, some lamps in the panel might have been damaged and will need to be replaced.

This can be from excess voltage or current from power surge. In some other cases, the red light flashing with black screen can also be due to faulty power supply board or sometimes, just a mere software glitch causing the TV to be stuck in standby mode.

However, if you are experiencing the issue on Hisense Roku TV, then there is a separate guide to fix red light flashing issue on Hisense Roku TVs.

That said, let’s look at how to fix this issue in Hisense TVs.

How to Fix Hisense TV Red Light Blinking 3 Times

If your Hisense TV is blinking red light 3 times, you need to power cycle it. To do that, turn off your TV and unplug it from the power outlet. Leave it unplugged for 60 seconds. While unplugged, press the power button on the TV for 30 seconds. Now, plug the TV back and turn it on. The red blinking light should stop. 

1. Power Cycle your TV

I’ll let you in on a little secret – No matter what issue you have with your TV (as long as the set is still intact), always power cycle it first. You will be surprised at the number of issues a simple power cycling can fix on any TV.

If your TV is stuck in standby mode with 3 repeated flashes or there are other software related issues, this will help you fix it quickly and clear the error.

Could it end up being a more technical hardware issue? Definitely. However, until you do this, don’t try the next thing yet.

With  that said, here’s how to power cycle your Hisense smart TV:

  • Unplug your TV from power outlet
  • Leave it unplugged for 60 seconds
  • While unplugged, press the power button on your TV for 30 seconds (not the one on the remote)
  • Plug the TV back into the power source and try to turn it on

If the red light stops flashing, good. Otherwise, move on to the next tip.

2. Check for Defective Backlight

Based on Hisense TV blinking codes, Hisense TV red light blinking 3 times is often an indication of LED rail shutdown which can be caused by excess voltage or current from power surge. In other words, some lamps in the panel might have been damaged leaving you with a defective backlight.

In that case, you can start with a flashlight test to check if the backlight is defective.

So, how do you check if the issue is with your TV backlight?

  • First, make sure your TV is plugged into the power outlet and you have pressed the power button the normal way you get it to turn on
  • In addition, make sure that you’ve done all the steps shown above (that way, you can be sure your TV did actually respond to the power signal).
  • Next, point a flashlight to your TV screen (you can also move it around the screen),

If your TV backlight is working well, all you should see is the reflection of the flashlight. However, if you can see dull images on the screen while pointing the flashlight, then your TV backlight is defective.

You can watch the video below for a visual demonstration of the process.

A more accurate way to check for faulty backlight is to actually disassemble the TV and test the backlight strips. Here’s how to do that:

  • Open up the TV and test the lamps in the panel. You can use a 3V power source (2 AA batteries) to test each lamp one at a time. Once you find faulty ones, replace them. This will take you more time since you have to test each lamp and replace faulty ones.
  • While it’s much cheaper to replace individual LEDs, the issue may happen again since this could indicate a bad batch.
  • Your best bet is to replace the entire LED strip which is not only easier but also a better solution.

Replacing faulty LED backlight strips or installing a new backlight inverter board will fix the issue 9 out of 10 times.

If it’s not coming from a faulty backlight, then it’s more than likely the power supply board.

3. Check for Connection Issues 

This only applies to you if your Hisense Vidaa OS or android OS smart TV is blinking 3 times while the TV is on and there’s picture, because you need that for this particular method. However, if your TV is not even showing any picture at all, just move to the next fix.

Now, let’s continue.

Your Hisense smart TV is likely disconnected from your network, probably because you restarted or unplugged your internet router, and your TV is failing to automatically connect back to the router.

So, go to your Hisense smart TV settings and reset the Wi-Fi connection. Once done, reconnect your TV back to your Wi-Fi and the red light should stop blinking.

4. Inspect the Power Supply Board

If the issue is not coming from a faulty backlight (either after doing the test or having replaced the faulty bulbs and still experiencing the issue), then next thing you need to check is the power supply board.

Capacitors on the power supply board can receive a surge and then fail. Most times, you can detect faulty capacitors by visual inspection when you open up the panel.

If a capacitor is faulty, some of the signs you might see include:

  • The capacitor is bulging at the top
  • The capacitor is leaking
  • Corrosive layer on one or both legs of the capacitor
  • Bottom of the capacitor is pushed out

Once you see any of the above visible signs on the capacitor, then you need to remove and replace such capacitor.

NOTE: The capacitor may be faulty and not show any visual sign. Hence, the most accurate way to check in such case will be to use a multimeter to check the voltage, and compare it to the expected/labelled voltage of the capacitors. If you see a wrong voltage reading on the multimeter, then it is faulty even if there is no visual sign.

To remove the faulty capacitor:

  • Carefully take note of the pin on the board that the capacitor is attached. You should do the removal with a soldering iron (do not force pull it out)
  • With the heated soldering iron, carefully apply pressure from the back of the board on the pin for the faulty capacitor until it melts.
  • Then, you can go ahead and remove it.
  • Once you have gotten the new capacitors, replace the old faulty one you removed using a soldering iron.

While replacing the capacitor, you should know the following:

  • The new capacitor must be placed in exactly the same direction as the old damaged one (this is why I advised taking some pictures of your board before removing anything earlier).
  • Ideally, you should replace the capacitor with a new one that matches the ratings (Voltage, Temperature and Micro farads). In case where you can’t get the exact value for the 3 ratings, you can get one that has voltage and temperature that is higher that that of the old capacitor but not lower. The micro farad can also be slightly higher, but not lower.

Once you replace the faulty capacitors, turn on your TV and the red blinking light should stop.

5. Contact Hisense Support

If any of the steps above is too technical for you (especially if you still have warranty) or you still couldn’t get your Hisense TV to stop flashing red light 3 times, go ahead and contact Hisense support for technical support.

Alternative, you can get it fixed at any good repair shop or just buy a new smart TV.

  1. I have 4 Hisense TVs that did this and now my bedroom tv is doing this. Nothing work in troubleshooting it. I will never buy another Hisense TV. Now I have these tvs that I need to get rid of. Hisense customer service in so many words telling you to buy a new tv. It’s driving me insane.
