Blinking Once — TV stuck in standby mode

If your Hisense TV’s red light blinks once, the television is stuck in standby mode.

This isn’t a problem, as the television is simply waiting for an action on your end.

Quick Fix: Press the power button on your remote control or television to resolve this issue. It should turn on immediately, and the red light should stop blinking as the Hisense TV is no longer in standby mode. If this doesn’t work, ensure the remote control has batteries and try again. If that doesn’t work, unplug and replug the television in to reset the connection.

Blinking Twice — Power supply issue

If your Hisense TV’s red light blinks twice, the television may have a power supply issue.

The television is most likely experiencing an unstable voltage supply or problem with the power board, causing it to not work properly.

Quick Fix: You’ll want to soft reset your television. Unplug it from the wall, then plug it back in after 60 seconds. This will help about 80% of you. In other cases, you’ll want to contact Hisense support or a technician to identify and fix the diagnosed problem.

Blinking Three Times — Inverter circuit or backlight issue

If your Hisense TV’s red light blinks thrice, takes a break, and does it again, there might be a problem. This blinking pattern can mean trouble with two parts of your TV: the backlight and the inverter circuit.

The backlight’s job is to light up your screen. The inverter circuit’s role is to give power to the backlight. If either of these parts isn’t working right, your screen might go dark or show other visible problems.

Quick Fix: Sorting out issues with the backlight or inverter circuit can be quite a challenge for everyday folks. These parts require certain skills and special tools to identify and mend. Your smartest move? Reach out to the support team at Hisense or a skilled technician. They can pinpoint the problem, check if you need a fresh backlight, fix the inverter circuit, or discover if there’s another hidden issue.

Blinking Four Times — Video processing or mainboard issue

When you see the red light on your Hisense TV flash four times, then stop, and start flashing again, there might be an issue. This could indicate a problem with the mainboard or the video processor. The mainboard is like the brain of your TV, controlling everything it does. The video processor is what makes the pictures appear on the screen. If either part isn’t working right, you might notice the picture is missing, looks odd, or your TV might not even turn on at all.

Quick Fix: It’s a tough task when it comes to sorting out issues with your TV’s motherboard or its video processing unit. You’d be best off getting help from a professional. You could get in touch with Hisense’s customer service or a skilled repair person. They’re trained to figure out the issue and see if the motherboard needs repair or replacement. It’s key to rely on these pros because if you try to fix it by yourself, you could damage your TV even more.

Blinking Five Times — T-CON board issue

If you see a red light flashing five times, then taking a short break before starting over might mean there’s an issue with the T-CON board. This board is like the traffic cop for your TV—it helps pass information between the mainboard and the screen. When it doesn’t work right, you might notice weird pictures, lines across the screen, or sometimes, no picture at all.

Quick Fix: Dealing with a T-CON board problem can be pretty challenging. Therefore, it’s best to seek advice from experts. You should get in touch with Hisense’s customer service or a professional repair person. They’ll help determine whether the T-CON board needs a repair or a total replacement, getting your TV back in its best condition. If you try to handle this on your own, it could create even more issues. Let those with expertise handle such matters is usually a good idea.

Blinking Six Times — Internal temperature sensor or cooling system issue

When you see the red light on your Hisense TV flash six times, pause, then start flashing again, there might be an issue. It could mean something is wrong with the TV’s temperature sensor or cooling system.

Making sure your TV is well-ventilated and at the right temperature is key. This helps your TV run smoothly and last longer. If your TV gets too hot, it might not work as well, it could stop working sooner than it should or break for good.

Quick Fix: Your TV needs to breathe! This means it needs plenty of space around it, so don’t box it in somewhere without good airflow. Double-check that it’s not hugging it too closely if it’s on the wall. Keep it out of the hot sun and away from radiators, too.

Now, if your TV keeps flashing, even though it’s got enough fresh air, it’s time to call Hisense support or a skilled technician. They’re the pros who can figure out what’s wrong with your TV, like a hiccup with the temperature sensor, cooling system, or another part. Trust them to fix things so you won’t risk making the problem worse.

Blinking Seven, Eight, or Nine Times — Backlight issue

Your Hisense TV is giving you trouble. The red light flashes 7, 8, or 9 times, but there’s no picture, right? This suggests that your TV’s backlight may be having issues.

You might see a sequence where the power light flashes seven times, takes a break, and then flashes three more times, totaling ten. Alternatively, the red light might flash slowly once, followed by seven quick flashes. No matter the flashing pattern, there are some steps you can take.

First, try pressing the power button to turn on your TV. Pay close attention to any sounds from the TV. If you can hear something but there’s no picture, it’s likely the backlight isn’t functioning as it should.

Another method to test the backlight involves using a flashlight. Shine the flashlight directly onto your TV screen. If your backlight is busted, you should be able to see some faint images on the screen. This can happen even if the TV is on and running properly, just not displaying a clear picture.

NOTE: If it blinks nine times, it’s most likely a backlight voltage specific issue, but the instructions remain the same for fixing it.

Quick Fix: Fixing issues with your TV’s backlight or a part called an inverter circuit can be pretty tough if you’re not an expert. You need special knowledge and tools to do it. So, what should you do? Contact Hisense’s help team or a TV repair person. They know how to find and fix the problem, whether it’s a broken backlight, a damaged inverter circuit, or something else you can’t see.

Blinking Ten Times — Faulty powerboard, mainboard, or LED driver/strips

When your Hisense TV’s red light flashes 10 times, this could be due to a defective LED driver or LED strips, a malfunctioning power board, or a problematic main board.

Suppose your TV’s red light blinks 10 times and then turns off, just as it usually would when it starts showing an image, but this time, no picture appears. In this case, you most likely have a faulty LED driver or LED strips. Often, you’ll still hear sound, but there will be no image on your screen.

If you notice that the red light on your Hisense TV starts flashing after you hit the power button, it indicates that the TV is getting power from the main board but can’t distribute it to power up. This issue suggests that your power supply board might be damaged due to a faulty capacitor or diode.

NOTE: If the TV’s red light begins to flash the moment you plug it into an electrical outlet, it’s likely a problem with the main board. This is because the main board controls the initial power-on command.

Quick Fix: Start by checking all the LED strips. You can do this using an LED tester or a battery. If all the LED strips are in good shape, your next step should be to replace the LED driver on the power supply board. Alternatively, you might need to replace the entire power supply board.

If replacing these parts doesn’t solve the problem, swapping out the main board might be time. You can identify whether the power supply or main board is the issue by testing each one with a meter.

The good news is these boards are designed to be easily replaced – they’re plug-and-play, so you don’t have to worry about soldering anything. All you need is a screwdriver to open up the TV, locate the troublesome board, disconnect it using the plastic connectors, and replace it with a compatible working board.
