Why Does Hisense TV Keep Restarting?
Understanding why your Hisense TV keeps restarting is the first step to solving the problem. Restarting issues can arise from both hardware and software complications, ranging from a faulty power supply to corrupted system updates or incompatible apps.
Common causes include:
- Power supply interruptions or faulty adapters.
- Outdated or corrupted firmware/software.
- Bad HDMI cables or connected devices.
- Overheating or internal hardware faults.
- App-level glitches or RAM overload.
- Dust, moisture, or even bugs inside the hardware.
Identifying the root cause quickly helps you apply a focused solution, saving time and money.
The Quick Fixes You Should Try First
Before you open your toolbox or contact Hisense support, run through these basic checks. Often, a quick fix can resolve what seemed like a big issue.
Power Cycle Your TV – The most straightforward solution is often a simple power cycle.
Steps for a Power Cycle:
- Turn off the TV with the remote.
- Unplug the power cable from the wall outlet.
- Wait for 3–5 minutes.
- Plug the TV back in and power it on.
A power cycle clears minor bugs and resets temporary memory. This often stops random restarts, especially after a recent power surge or temporary glitch.
Check Your Power Source and Cables – A weak, inconsistent, or faulty power supply is a major culprit behind TVs that keep rebooting. Inspect your power cable for kinks, wear, or exposed wires. Consider plugging your TV into a different power outlet, and use a surge protector if you aren’t already.
If you notice loose connections, burnt smells, or visible wire damage, replace the power cord immediately. Many Hisense TV models use universal power cables.
Hisense TV Need a Software Update – Hisense regularly releases firmware updates to fix bugs and boost performance. However, outdated or corrupted software can crash the system and trigger restarts.
How to Update Hisense TV Firmware
- Connect your TV to the internet (via Wi-Fi or Ethernet).
- Go to Settings > Support > System Update.
- Select Check Firmware Update or Software Update.
- Install any available updates.
Sometimes, updates fail midway and can get the TV stuck in a restart loop. If your TV never gets past restarting, try downloading firmware from the official Hisense support page onto a USB drive. Insert the drive into your TV and follow the on-screen instructions.
Tips: Always ensure your internet connection is stable. Don’t unplug during the update.
Overheating and Hardware Issues – Heat can impact the internal components of your TV, leading to automatic shutdowns and restarts as a safety measure. Dust buildup and poor ventilation are common triggers.
Steps to Rule Out Overheating
- Ensure the back and sides of your TV are unobstructed.
- Clean dust from vents using canned air or a soft brush.
- Place your TV in a well-ventilated spot away from direct sunlight and heat sources.
If overheating persists and you hear clicking noises or smell burning plastic, unplug your TV and seek professional repair.
Check Your Connected Devices – Smart TVs like Hisense models often handle multiple HDMI, USB, and AV inputs. A malfunctioning HDMI cable or a faulty streaming device can send error signals that force restart.
Troubleshooting External Devices – Disconnect all devices (game consoles, USB drives, streaming sticks, soundbars). Turn the TV back on. If it runs smoothly, reconnect devices one by one.
Replace bad HDMI cables with tested alternatives. High-quality cables, like this Choice HDMI cable, can prevent future glitches.
App and Memory Glitches – Hisense smart TVs run on VIDAA, Roku, or Android TV platforms, each with a suite of downloadable apps. Too many background apps or one buggy app can overload the TV’s memory, causing restarts.
App Management Tips
- Remove unused or suspicious apps.
- Clear the cache/data of heavy apps (e.g., streaming services).
- Perform a factory reset if the issue persists (see next section).
Note: Back up account logins and settings before factory resetting.
Perform a Factory Reset (as a Last Resort) – If your Hisense TV keeps restarting after all the above attempts, a factory reset can wipe out software-related bugs.
This step reverts your TV to its original factory settings, erasing all customizations and downloaded apps.
How to Factory Reset Hisense TV
- Go to Settings > Device Preferences > Reset (naming may vary by model).
- Choose Factory Data Reset and follow prompts.
- For TVs stuck in a loop, use the physical reset button (usually near HDMI ports), holding it for 15-30 seconds.
Once the reset is done, set up your TV from scratch. Only reinstall essential apps and monitor for issues.

FAQs on Hisense TV Keeps Restarting
Why does my Hisense TV restart randomly, even after a factory reset?
A random restart after a factory reset indicates a deeper problem, usually with internal hardware. Potential causes include blown capacitors, a faulty mainboard, or persistent overheating issues. If standard fixes and resets don’t work, professional diagnostics are necessary.
Replacing electronic components inside the TV without expertise can also void warranties or make the problem worse. If your TV is under warranty, always contact Hisense support before opening the device.
Is this a widespread issue for Hisense TVs or just my model?
Restarting glitches are reported across various Hisense TV models, regardless of year or operating system (VIDAA, Roku, or Android TV). However, the frequency and root cause may vary.
Firmware glitches are often fixed in newer software updates, while older TVs may develop hardware faults over time. Checking relevant user forums and the Hisense support site can help determine if your model is affected by a known issue.
Will using a universal power adapter or third-party remote affect restarts?
Generally, a universal power adapter or remote from a reputable brand should not trigger restart loops, but you must match voltage and amperage exactly as per your TV’s specifications.
Cheap, off-brand adapters can deliver inconsistent current, leading to problems. Stick to verified power cords whenever possible.
My Hisense TV keeps restarting only when streaming – what’s causing this?
Streaming-related restarts often tie back to software, apps, or internet connectivity. Streaming apps (YouTube, Netflix, etc.) consume more RAM and processing power. Corrupted app data, overloaded memory, or an unstable Wi-Fi connection can cause mid-stream crashes.
Try clearing the app cache, reinstalling the problematic app, and resetting your router. If the TV’s firmware is outdated, updating it can resolve many streaming issues as well.
How can I check if my power outlet is causing the restart loop?
Plug your Hisense TV into a known, reliable outlet (preferably one powering another device without issues). If your TV works in a different room or when connected through a surge protector, it suggests the original outlet was the issue.
Outlets with loose wiring or fluctuating voltage can damage sensitive electronics gradually or cause abrupt restarts. If your outlet feels warm or you detect burning smells, have a qualified electrician inspect it immediately.
Can bad weather or power surges cause repeated restarts?
Absolutely. Lightning strikes, brownouts, or brief power outages can damage internal circuits or corrupt software. Modern TVs are sensitive to power surges, making surge protectors essential for every TV setup.
After severe weather, perform a power cycle and consider a full reset. If the issue persists, inspect your power and HDMI cables for visible damage.
How do I back up my Hisense TV before a factory reset?
While Hisense TVs don’t yet offer robust cloud backup like smartphones, you can jot down your Wi-Fi passwords, streaming app logins, and preferred settings.
Some Android-based models allow partial backup through Google account sync, but most settings will need to be re-entered after a reset.
Take photos of app layouts and menu settings to restore your customizations more easily afterwards.
