Fix Hisense TV Stuck in Reboot Loop
By Robert Jones · 2021-09-27
If your Hisense TV is stuck in that maddening reboot loop, don't chuck it out just yet! I've spent years sorting out these tech headaches, and I'm here to share the common fixes that can get your Hisense back on track without needing a new one.
I've had my hands on countless tellies over the years, testing them for SpeakersMag.co.uk. Hisense sets, in particular, often punch above their weight for the money, offering a cracking picture and smart features without breaking the bank. But, like any bit of tech, they can sometimes throw a real spanner in the works. One of the most infuriating glitches I've seen, and surprisingly common for Hisense, is the dreaded reboot loop. You know the one: the Hisense logo flashes up, then it goes black, then the logo again, endlessly. It's like the TV can't quite make up its mind whether to start or just keep teasing you. Now, before you start eyeing up the recycling bin, there are quite a few things we can try to get it sorted. I've seen these methods rescue everything from budget 32-inchers to some of the fancier 65-inch ULEDs I've had in my own workshop and home. So, let's get stuck in. **Quick Verdict:** Most Hisense reboot loops can be fixed with a bit of patience and a hard reset. ### Who it's for: * Anyone with a Hisense TV stuck in a reboot cycle. * DIY enthusiasts looking to troubleshoot before calling support. * Those wanting to save a bit of cash by not needing a repair technician. * Owners of older Hisense models out of warranty. ### Who should skip it: * People who aren't comfortable fiddling with electronics. * Those with brand new Hisense TVs still under warranty (call support first). * If your TV has visible physical damage.  *Fix Hisense TV Stuck in Reboot Loop — tested in the SpeakersMag workshop.* ## The Age-Old Trick: Power Cycling Honestly, it sounds so ridiculously simple, doesn't it? But you'd be utterly gob-smacked how often this little manoeuvre sorts out a multitude of tech woes. It's the classic "have you tried turning it off and on again?" line, only when your TV's stuck in a loop, you can't just press a button. You've got to be a bit more direct. I've lost count of the times I've been called out by a mate, or had a unit sent to me for testing that's playing up, and this has been the magic bullet. It's my absolute first port of call, every single time. ### How to Power Cycle Your Hisense TV: 1. **Unplug the TV completely.** And I mean completely. Don't just turn it off at the wall socket; pull that chunky power cord right out of the back of the TV itself. This is crucial. What you're doing here is allowing all the residual electrical charge stored in the TV's capacitors to drain away. Think of it as a complete brain dump for the TV's internal gubbins. It clears out any lingering glitches or corrupted bits of memory that might be causing the loop. 2. **Wait a good 5-10 minutes.** Now, this isn't a quick flick of a switch. You need to give it time. Go and put the kettle on. Make yourself a proper builder's brew. Check your phone for those emails you've been ignoring. The longer you leave it unplugged, the more certain you can be that every last bit of juice has left the system. I usually aim for at least ten minutes, especially if it's a persistent problem. This ensures a clean slate when you power it back up. 3. **Plug it back in.** Make sure it's a snug fit, both at the TV end and at the wall socket. Sometimes a loose connection can cause all sorts of bother. Once it's plugged back in, try powering it on normally with the remote or the TV's power button. Honestly, I've seen this fix more than a few gadgets over the years. It's simple, it costs nothing, and it's often all you need. If you're lucky, your TV will fire up like nothing ever happened, and you can get back to watching the footie or whatever you were doing. If not, don't fret; we've got more tricks up our sleeve. ## The Stubborn Set: Hard Reset Combination Right, so the simple power cycle didn't do the trick? No worries, sometimes you need to be a bit more... assertive. This next method is about forcing the TV to properly shut down and then try to boot clean, bypassing whatever software hiccup is causing the loop. Certain button combinations can sometimes kick a stubborn Hisense TV back into life, almost like resetting its internal sequence. I remember a few years back, I had a 55-inch Hisense ULED that a neighbour brought round, doing exactly this. The power cycle just wasn't cutting it. He was ready to give up and buy a new one, but I told him to hold his horses. This particular method ended up doing the job, and he saved himself a grand or so. ### Performing a Hard Reset: 1. **Unplug the TV again.** Yes, we're going right back to square one with a complete power cut. Same as before, pull the cord out of the TV itself. We want no residual power mucking things up. 2. **Locate the physical power button on the TV.** This is crucial. Do *not* use the remote control for this step. Most Hisense TVs have a physical button, often on the bottom right or centre, or sometimes on the back. It might be a single button that does power and input, or a dedicated power switch. Press and hold this button down firmly. 3. **While still holding the physical power button, plug the TV back in.** This is the tricky bit, so make sure you've got a free hand or a helper. You're essentially telling the TV, "Right, you're getting power, but you're also staying off until I say so." 4. **Continue holding the power button for about 30-60 seconds after plugging it in.** Don't let go too soon! This extended hold helps to discharge any remaining energy and can sometimes force the TV into a recovery mode or clear out a corrupted state in the boot sequence. You might see the Hisense logo flicker or stay on, or nothing at all. Just keep that button pressed. 5. **Release the button and try powering on.** After the 30-60 seconds, release the power button and then try to power the TV on normally using the remote or a quick press of the physical button. With a bit of luck, this will have bypassed whatever was causing the loop, and the TV will boot up properly. If it does, make sure you let it run for a while, maybe check for system updates (more on that later), and don't switch it off at the mains for a few days if you can help it. ## Firmware Follies: The USB Update Gambit Alright, if the basic resets haven't worked, it's time to consider something a bit more involved: the firmware. Think of firmware as the TV's basic operating system, the underlying code that makes everything tick. Sometimes, this code can get corrupted during an update, a power cut, or just a random glitch. When that happens, the TV might not know how to boot up properly, leading to our dreaded reboot loop. This isn't as scary as it sounds, but it does require a bit of preparation. I've had to do this more than once for various devices, not just TVs. It's a bit like giving the TV a fresh brain. If your TV is trying to load a corrupted operating system, it's going to keep failing and restarting. A fresh install of the firmware from a USB stick can bypass this problematic boot sequence entirely. ### Preparing for a USB Firmware Update: 1. **You'll need a USB flash drive.** A small one, 4GB or 8GB, is usually plenty. Make sure it's formatted to FAT32. Most drives come this way, but it's worth double-checking. Don't use a massive external hard drive; stick to a simple USB stick. 2. **Find your TV's exact model number.** This is absolutely critical. You'll usually find it on a sticker on the back of the TV itself. It'll be something like "H65U8B" or "50A7200GTUK". Write it down. Getting the wrong firmware for your model can cause more problems than it solves, potentially bricking the TV, which is a right pain to fix. 3. **Head to the Hisense support website.** Go to the official Hisense UK website (or your regional equivalent). Navigate to the "Support" or "Downloads" section. You're looking for firmware updates. Input your exact model number. Take your time here. I cannot stress enough how important it is to get the correct file. 4. **Download the firmware file.** It will usually be a compressed file, often a .zip or .rar archive. Once downloaded, extract its contents. You're looking for a file that often ends in .pkg or has a similar, specific name for firmware. Crucially, the extracted file (or files) needs to be placed directly into the *root directory* of your USB stick. Don't put it in a folder; it needs to be accessible immediately when the TV scans the drive. ### Performing the USB Firmware Update: 1. **Unplug the TV.** You know the drill by now. Completely remove the power. 2. **Insert the USB drive.** Pop your prepared USB stick into one of the USB ports on the TV. Usually, any USB 2.0 port will do, but if your TV has multiple, try the one labelled "Service" or "USB1" if it exists. 3. **Plug the TV back in while holding the physical power button.** This is a variation of the hard reset. Plug the power cord back in while keeping that physical power button on the TV pressed down. Keep it held down for at least 30-60 seconds, as before. The TV might detect the USB stick and automatically start the update process. You might see a progress bar or a message indicating a firmware update is in progress. 4. **If it doesn't start automatically:** Try releasing the power button after 30-60 seconds and then quickly pressing it again. Some Hisense models require a different button combination to enter recovery mode, often a combination of Power + Volume Down, or similar. Check your TV's manual or the Hisense support page for specific instructions for your model if the standard method doesn't trigger the update. 5. **Let the update complete.** This can take a good few minutes. Do not, under any circumstances, unplug the TV or remove the USB stick during this process. You'll see progress on the screen. Once it's done, the TV should restart. Remove the USB stick *after* the TV has rebooted successfully. This method can be a lifesaver, particularly if the loop started after a dodgy software update. It's a bit more fiddly, but often well worth the effort. ## Factory Reset: Wiping the Slate Clean If you've tried the above and your Hisense TV is still playing up, a factory reset might be the next step. This is a bit more drastic, as it wipes all your settings, downloaded apps, Wi-Fi passwords, and calibration settings. It essentially takes your TV back to how it was when it rolled off the production line. However, it's often the cure for deeply ingrained software glitches that aren't fixed by a simple power cycle or firmware re-installation. I've had to do this on my own test sets when they've become sluggish or developed odd behaviours. It's annoying to set everything up again, but it's far less annoying than a TV that won't switch on properly. ### How to Factory Reset (if you can get into a menu): If, by some miracle, your TV occasionally boots up for a few seconds before looping, or if one of the earlier methods gets it to stay on for long enough, you can perform a factory reset through the TV's settings menu. This is the ideal way to do it. 1. **Navigate to Settings.** Look for the cog icon or "Settings" on the main menu. 2. **Find "System" or "Device Preferences."** The exact path varies a bit between Hisense models and their smart platforms (Android TV, VIDAA U, etc.). 3. **Look for "Reset," "Factory Reset," or "About" -> "Reset."** You'll usually get a warning message about losing all data. Confirm you want to proceed. 4. **The TV will restart.** It will then guide you through the initial setup process, just like when it was new. ### How to Factory Reset (if stuck in a loop): This is the more likely scenario. When you can't get into the menus, you'll need to use a button combination. This varies wildly by model, so *check your specific TV's manual or Hisense support page* for the precise method. However, here are some common combinations I've encountered: * **Power + Volume Down:** With the TV unplugged, plug it back in while holding the physical power button and the volume down button simultaneously on the TV itself. Hold for 30-60 seconds. * **Power + Input/Source:** Similar to above, but holding the input/source button instead of volume down. * **Service Button:** Some Hisense TVs have a tiny "service" or "reset" button, often recessed and requiring a paperclip to press. This is usually near the other physical buttons or ports. Unplug, press and hold this, then plug back in. This is less common on consumer models, more on commercial displays, but worth checking for. If you successfully trigger a factory reset this way, the TV should show a message indicating it's resetting or will simply reboot into the initial setup wizard. ## Last Resorts and When to Call for Backup If you've diligently worked through all these steps – power cycling, hard resets, a USB firmware update, and a factory reset – and your Hisense TV is still stubbornly stuck in that reboot loop, then it's time to consider that the problem might be a bit more serious. At this point, we're likely looking at a hardware fault. ### Common Hardware Culprits: * **Faulty Power Supply Board:** This is a very common cause of reboot loops across many TV brands. If the power supply isn't delivering stable voltage, the TV tries to boot, fails, and restarts. You might notice a clicking sound if this is the case, but not always. Replacing this board can be relatively straightforward if you're comfortable with electronics, but it's definitely a job for a qualified technician or someone who knows their way around a multimeter. * **Faulty Main Board/Motherboard:** This is the brains of the operation. If components on the main board, like memory chips or the main processor, have failed or become corrupted, the TV simply won't boot. This is generally a more expensive fix, as the main board is a key component. Again, a technician's job. * **Bad Capacitors:** On older sets, capacitors on the power supply or main board can dry out or swell, leading to unstable power delivery. This is usually visible upon inspection, but opening up a TV requires care. * **Backlight Issues:** Less common for a full reboot loop, but sometimes a failing backlight can cause power issues that prevent a full boot. The TV tries to light up, draws too much current, and shuts down/restarts. ### When to Seek Professional Help or Consider a New TV: * **Still under warranty?** Absolutely, get onto Hisense customer support immediately. Don't mess around with firmware or factory resets if you can help it, as some manufacturers can be picky about what counts as "user intervention" voiding a warranty. Let them guide you or arrange a repair/replacement. * **Out of warranty, but a relatively new TV (1-3 years old)?** It's worth getting a quote from a local TV repair shop. A power supply board replacement might only be £100-£200, which is a lot cheaper than a new TV. Get a couple of quotes if you can. * **Older TV (3+ years old) and out of warranty?** Honestly, for anything more than a simple board replacement, it might be more economical to start looking at a new set. The cost of diagnosis and repair for a main board, combined with the age of the panel, often makes a repair uneconomical. Modern TVs, especially Hisense, offer so much more in terms of picture quality and features for a reasonable price now. You might find a great deal on a newer ULED model that makes the old one seem ancient. ## Comparison: Troubleshooting Steps Here's a quick rundown of the methods we've discussed, their difficulty, and likelihood of success: | Method | Difficulty | Effectiveness for Reboot Loop | Risk of Data Loss | Notes | | :------------------- | :--------- | :---------------------------- | :---------------- | :-------------------------------------------------------------------------------------------------- | | **Power Cycle** | Very Easy | High | None | First port of call.

What does that mean? **A:** A clicking sound, especially if it's rhythmic or happens just before the Hisense logo appears and then disappears, often points towards a problem with the power supply board. It's trying to power up, encountering a fault, and then cycling. This is usually a job for a technician, as replacing the power board involves opening up the TV, dealing with mains voltage, and correctly identifying and fitting the right component. ### Q2: Can a bad HDMI cable cause a reboot loop? **A:** It's unlikely a faulty HDMI cable would cause a continuous reboot loop *of the TV itself*. A bad cable might cause no picture, flickering, or audio dropouts, but typically the TV would still power on and stay on, perhaps displaying an error or just a black screen. However, a faulty device connected via HDMI could potentially interfere with the TV's boot sequence. If you're trying to troubleshoot, it's always a good idea to disconnect *all* external devices (HDMI, USB, aerial) and try to boot the TV purely on its own to rule out external interference. ### Q3: My TV started looping after a power cut. Is that common? **A:** Absolutely, yes. Power cuts or sudden surges can be a common trigger for a reboot loop. An unexpected power loss can interrupt a crucial process, like a background firmware update, or even damage sensitive components on the power supply or main board. This is precisely when a power cycle or a USB firmware update is most likely to sort things out. It's why I always recommend plugging expensive electronics into surge protectors, even if it feels a bit overkill. ### Q4: How can I prevent this from happening again? **A:** While you can't guarantee against every glitch, there are a few sensible precautions. Firstly, always ensure your TV is connected to a reliable power source, ideally via a surge protector. Secondly, allow your TV to complete any firmware updates without interruption. Don't pull the plug or turn it off while an update is in progress. Finally, if your TV allows it, disable "Fast Start" or "Quick Start" modes in the settings. While convenient, these modes often keep parts of the TV semi-powered, which can sometimes lead to instability over time compared to a full power cycle each time it's turned off. ## Final Word Seeing your Hisense TV stuck in a constant reboot loop is bloody frustrating, there's no two ways about it. It makes you feel utterly powerless. But, as I've found time and again in my twenty-odd years of tinkering with speakers, amps, and now tellies, these things often have a simpler fix than you might initially imagine. Don't immediately despair or assume it's a goner. Start with the easy stuff – that good old power cycle – and patiently work your way through the options. More often than not, it's a software hiccup rather than a catastrophic hardware failure. With a bit of patience and following these steps, you've got a decent chance of bringing your Hisense back from the brink. If you do get it going, make sure to keep an eye on it for a few days, and maybe check for any available system updates that could stabilise things further. And if, after all that, it's still playing up, then it's time to either call in the pros or start browsing for a shiny new upgrade. There are some cracking deals out there these days, especially on the bigger screens. But let's hope it doesn't come to that, eh? Good luck, and let me know how you get on!
