Hisense TV Flickering ON and OFF: Why is this Bug So Popular?
Budget-friendly Smart TVs like Hisense are extremely popular among new-age users. Despite being significantly more affordable, these TVs typically deliver high-quality user experiences. However, the number of users complaining about the Hisense TV blinking issue has increased a lot in the past year, mainly due to two factors:
The Rising Popularity of Hisense TVs: In 2022, Hisense increased its TV sales by 16%, becoming the second-best-selling smart TV of the year. Many of these recent buyers have faced and complained about the Hisense Roku TV turning on and off problem online.
Lack of Clear Instructions from the Company: The long catalog of Hisense TVs contains products powered by Amazon Fire TV, Google TV, Xumo TV (from Comcast), and of course Roku OS. This fact alone confuses many users. On top of that, the instructional guide on fixing the Hisense Roku TV keeps flashing on and off issue from Roku (read it here) is also extremely confusing.
Unlike Roku, I will explain how to fix the Hisense Roku TV blinking on and off issue in simple language using easy-to-follow instructions. Before that, let’s try to narrow down the reasons why you are facing this problem.
Why Is My Hisense Roku TV Blinking ON and OFF?
Your Hisense Roku TV could be blinking on and off issue for any one of the following reasons:
Firmware/Software Issues: Outdated firmware/software can lead to the rise of glitches that cause your TV screen to flicker.
Loose or Poor-Quality Cables: Loose cables that aren’t securely connected can cause your screen to flicker on/off. The same goes for off-brand, poor-quality cables.
Settings Error: In some very rare cases, changes to the TV’s display settings may trigger glitches that lead to the screen flickering problem.
Poor Network: If the Wi-Fi signals your smart TV is receiving are weak or interfered with by nearby objects (blocked by surrounding devices, walls, or furniture) your smart TV screen may malfunction. The same issue can arise if your TV is located too far away from the Wi-Fi router.
If you suspect that poor Wi-Fi signals are the main reason why your Hisense Roku TV keeps flashing on and off, I recommend checking out the following video. It explains why certain Hisense TVs keep disconnecting from Wi-Fi networks and how to fix it:
Power Fluctuations: The worldwide transition to renewable energy sources has led to a global increase in power supply fluctuations. How does that impact your Hisense TV viewing experience? Well, fluctuations in the power supply can cause your TV screen to flicker. If left unaddressed, the flickering can quickly lead to all-out device failure.
Fixing Hisense Roku TV Blinking On and Off
Restart Your Hisense TV
First things first, manually turn off your Hisense smart TV. The Hisense TV restarting or flicking on/off issue is often caused by internal system glitches. Manually restarting the device can help get rid of these temporary bugs and glitches. Here’s a step-by-step guide on restarting your Hisense TV:
- On your TV remote control, press the Home button
- From the menu, enter “Settings”
- Navigate to the option titled “System”
- Select “Restart” and confirm your decision in the pop-up window
The TV will restart. If your Hisense TV keeps rebooting on its own, power-cycle it. Turn off the TV again. This time, unplug the cables and wait 60 to 120 seconds before powering the TV up again. Replug the power cables, turn the TV back on, and check if the flickering issue is solved.
Try Another Power Outlet
Ever experienced a hair dryer conking out in one socket and springing back to life in another? Your Hisense Roku TV might be pulling a similar stunt. Think of it like this: your TV might just be craving a different ‘juice bar’. So, if your TV is flashing that pesky red light, here’s a quick trick: unplug your TV from the wall outlet and then plug it into another power outlet. A TV blinking red light issue can sometimes be as simple as insufficient power. And yes, this sounds deceptively simple, but hey, even the geekiest tech aficionados miss this sometimes. If you’re still having issues after trying this, it’s onto the next step.
Turn off the energy-saving option on your Hisense TV
Energy-saving modes are like that friend who insists on going to bed early even when there’s a game night going on. It’s a good feature, don’t get me wrong. But sometimes, it can lead your Hisense Roku TV to blink as if it’s caught in some weird tech rave. Dive into your settings and turn off this option to see if it works. If your TV isn’t blinking post this, then voila! If not, hold tight, Sherlock, we’ve got more to explore.
Check your TV Hardware for Problems
If turning off the energy-saving mode is a no-go, let’s get a bit hands-on. Remember the last time you played detective, hunting for that lost game controller? Well, now it’s time to channel that energy to fix the Hisense TV. Grab a torch (or your phone’s flashlight), unplug your TV, and remove the back. Once inside, give those circuit boards a gentle dusting with compressed air. While you’re at it, check for any evident signs of damage on the capacitor, t-con board, power board, and inverter board. Using a multimeter can help you gauge the voltage and current on these components. But, if you feel this is way out of your tech comfort zone, it might be time to contact Hisense or a professional.
Unplug Your HDMI Cables
Ah, HDMI cables. Those nifty, yet occasionally mischievous, tech connectors. Here’s a revelation: if your Hisense TV is blinking or flashing, those HDMI ports or the cables themselves might be the culprits. An HDMI input not playing nice can make your TV go into a frenzy. So, go ahead, unplug your HDMI cables, give them a once-over, and maybe try using a different HDMI slot. If your TV works correctly post this – kudos, you just troubleshooted the issue! If not, well, we tried, and there are always more troubleshooting tips and tricks up the techie sleeve.
Check for Cable Damages
Visually inspect all the HDMI cables connected to your Hisense Smart TV. This includes all the cables that connect your gaming consoles, HDTVs, Blu-ray players, or other devices to your TV. Make sure that these cables are not loose, damaged, or insecurely connected to your TV. All of these flaws can lead to the Hisense Roku TV blinking on and off issue.
Unplug all the HDMI cables. Dust off all debris and dirt buildups. Replug them back into your device in a secure and tight manner. If possible, borrow some high-quality cables and test your TV. If the flickering issue disappears once you connect higher-quality cables to your TV, you may need to replace your old HDMI cables.
Adjust Picture Settings
Glitches may arise if you intentionally or mistakenly alter your TV’s display settings. To ensure that’s not the case, try restoring your Hisense smart TV’s default picture settings:
- Turn on your Hisense TV
- On the remote, press the Settings button
- Select “Picture”
- On the next page, scroll down and select the option titled “Restore Default Picture”
- Press “OK” to confirm your decision
If adjusting the display settings doesn’t fix the problem, try adjusting another feature: your Hisense TV’s built-in energy-saving feature. In some cases, this feature causes Hisense TV screens to draw less energy than they need to function efficiently. To ensure that’s not the case with your Hisense TV, take the following steps:
- Go to “Settings”
- Select “Picture”
- Select “Picture Mode”
- Select the option titled “Energy Saving”
- Turn off this feature and check if the flickering issue persists.
Update Your Hisense TV
If none of these basic solutions work and your Hisense TV keeps turning on and off repeatedly, it’s time to move on to some more complicated troubleshooting techniques. The first order of business is updating your Hisense Smart TV’s software follow these steps:
- Go to “Settings”
- Select “Device Preferences”
- Navigate to “About”
- Select “System Update”
- Choose the option titled “Check Now”
Wait for your TV to check for updates. If there are updates, download and install them. If updating your TV software doesn’t work, I highly recommend you contact the Hisense Support team. Inform the experts of all the steps you’ve taken. Factory reset your TV only if the experts ask you to. Here’s a simple video guide on how to factory reset Hisense Smart TVs:
Either factory reset your Hisense TV (with the company technician’s permission) or take your TV to a Hisense-certified repair technician. If hardware issues are to blame for your TV’s flickering problem, there’s nothing much you can do on your own at home. Hopefully, one of the solutions mentioned above will work before you need to take such a step!
Alright, tech crusaders, we’ve embarked on quite the journey together. From the moment your Hisense Roku TV started giving you the silent, blinking red light treatment, we’ve delved deep into the heart of this tech conundrum. Just like gaming levels, we tackled each issue step-by-step.
Remember the basics: when in doubt, plug your TV out and then plug it back in. Kind of like a power cycle for your electronic buddy. And if that red light blinks its naughty little eye at you again, try holding that power button down for about 30 seconds. Sometimes, all your TV needs is a gentle reminder that you’re the boss.
For those who’ve ventured further down the rabbit hole, perhaps you’ve faced the tough love of a factory reset. As painful as pressing and holding can be, especially knowing that a reset will erase those painstakingly customized settings, it’s sometimes the nudge your TV needs to get back into the groove.
