Like all electronic devices, Hisense televisions can experience technical issues that frustrate users. Understanding these common problems and their solutions can help extend the lifespan of your Hisense TV and avoid costly repairs or replacements.
The most common problem with Hisense TVs is the black screen issue, often caused by backlight failure, power supply malfunction, or software glitches. This is followed closely by power-related problems where the TV won’t turn on or repeatedly restarts, and audio issues including no sound or distorted audio. Software bugs, particularly in smart features, and remote control malfunctions round out the top five most prevalent issues.
Black Screen Problems
One of the most frequently reported issues with Hisense televisions is the black screen problem. This occurs when the TV powers on (often indicated by status lights), but the display remains black.
The primary cause of black screen issues in Hisense TVs is backlight failure. LED backlights have a finite lifespan, and when they deteriorate, the screen may appear black even though the TV is functioning otherwise.
Another common cause is a faulty T-Con (Timing Control) board, which synchronizes the display signals. When this component fails, you might hear sound but see no picture.
Power supply issues can also trigger black screen problems. Internal power components may not provide adequate voltage to the display panel, resulting in a black screen despite the TV appearing to be on.
Software glitches sometimes cause black screen issues that can be resolved without replacing hardware. These typically occur after firmware updates or due to corrupted system files.
To troubleshoot a black screen on your Hisense TV, try these steps:
- Perform a power cycle by unplugging your TV from the wall outlet for at least 60 seconds
- Check all cable connections, ensuring HDMI cables are securely connected
- Try different input sources to rule out issues with a specific connection
- Attempt a factory reset (usually via a pinhole reset button on the back of the TV)
- Look for visible light when shining a flashlight at the screen (which would indicate backlight failure if you can faintly see images)
“The backlight issue is particularly common with Hisense models from 2020-2023. Often the TV is otherwise functional – you can hear sound and the processor is working, but without backlight illumination, the screen appears completely black.”Electronics repair technician, Michael Chen.
If these troubleshooting steps don’t resolve the issue, the problem likely requires professional repair or component replacement, typically of the backlight array, power board, or main board.
Power-Related Issues
Power-related problems rank second among Hisense TV issues and manifest in several ways, from complete failure to turn on to random shutdowns or restart loops.
The most obvious power issue is when your Hisense TV won’t turn on at all – no lights, no sound, no response from controls. This often stems from problems with the internal power supply board or main board.
Intermittent power issues where the TV turns on briefly then shuts off are frequently reported with certain Hisense models, particularly in the R6 and U6 series. This behavior typically indicates a failing power board or thermal protection activating.
Red light blinking patterns can provide diagnostic clues. Different patterns (such as 2, 4, or 8 blinks) correspond to specific internal problems, from power supply issues to mainboard failures.
To resolve power-related problems with your Hisense TV:
- Check the power outlet by plugging another device to ensure the outlet works properly
- Inspect the power cord for damage and ensure it’s securely connected
- Perform a power cycle by unplugging the TV for 5 minutes
- Press and hold the power button on the TV itself (not the remote) for 15 seconds while unplugged
- Look for reset buttons on the back of the TV (sometimes hidden in small pinhole)
“Power supply issues account for approximately 35% of all Hisense TV repairs we see. The good news is that power boards are often replaceable components that cost significantly less than buying a new television.”
For persistent power problems, replacement power supply boards are available from electronics parts suppliers. A power board replacement for most Hisense models ranges from $25-50, making this a cost-effective repair compared to purchasing a new TV.
Audio and Sound Problems
Sound issues represent another common category of problems affecting Hisense televisions, ranging from complete audio failure to distorted or inconsistent sound quality.
The most frequently reported audio issue is complete sound loss, when the TV displays images normally but produces no audio whatsoever. This may result from incorrect settings, software bugs, or hardware failures.
Intermittent audio problems, where sound cuts in and out during playback, often indicate connectivity issues between the main board and the internal speakers or faulty speaker components.
Audio sync problems, where sound doesn’t match up with the images on screen, frustrate many Hisense users. This issue frequently occurs during streaming or with external devices connected via HDMI.
Distorted audio quality, including buzzing, static, or tinny sound, can stem from speaker damage or problems with the TV’s audio processing components.
To resolve sound issues on your Hisense TV:
- Check if the TV is muted or volume is set extremely low
- Navigate to sound settings and ensure the correct audio output is selected
- Test different input sources to determine if the problem is content-specific
- Perform a power cycle by unplugging the TV for 60 seconds
- Reset audio settings to factory defaults through the TV’s menu system
- Try an external speaker to determine if the issue is with the TV’s internal speakers
“Almost 20% of Hisense TV owners will experience some type of audio problem during the lifespan of their television,” Consumer electronics analyst, David Park.
For persistent audio problems, particularly those involving distortion or no sound at all, the issue may require replacement of internal components like the audio board or speakers. These repairs typically cost between $75-150 when performed by professional technicians.
Smart Features and Software Issues
As Hisense continues to develop more sophisticated smart TV platforms, software-related problems have become increasingly common across their product lineup.
App crashes and freezing occur frequently, particularly with streaming applications like Netflix, Hulu, and YouTube. These issues may stem from insufficient system memory or software conflicts.
Slow or unresponsive interfaces frustrate many Hisense smart TV owners, with lag occurring during menu navigation, input switching, or app launches. This often worsens over time as the TV’s operating system becomes outdated.
Wi-Fi connectivity problems plague many Hisense models, with users reporting frequent disconnections, inability to maintain stable streaming connections, or failure to connect to wireless networks altogether.
Software update failures represent a particularly troublesome issue, as interrupted updates can leave TVs in unusable states or “boot loops” where the device continually restarts without fully powering on.
To address software and smart feature issues on your Hisense TV:
- Restart your TV by unplugging it for at least 60 seconds
- Check for and install any available firmware updates
- Clear the cache for problematic applications through the settings menu
- Perform a factory reset (note this will erase all personalized settings)
- Ensure your home network provides sufficient bandwidth for streaming
- Consider using a wired Ethernet connection instead of Wi-Fi when possible
“Hisense uses multiple operating systems across their TV lineup, including Android TV, Roku TV, and their proprietary VIDAA platform,” Smart home technology specialist, Sarah Miller.
For more serious software problems like failed updates or boot loops, users may need to perform USB recovery procedures. Hisense provides firmware files on their support website that can be loaded onto USB drives to recover TVs with corrupted system software.
Remote Control and Input Problems
Issues with remote controls and input functionality round out the top five most common problems affecting Hisense televisions.
Unresponsive remote controls top the list of input-related complaints. Many users report their Hisense remotes stop working entirely or respond inconsistently to button presses.
Input recognition problems occur when the TV fails to detect connected devices or switches between inputs unpredictably. This often happens with HDMI connections to gaming consoles, streaming devices, or audio equipment.
CEC (Consumer Electronics Control) functionality issues are particularly frustrating, as this feature is designed to allow control of multiple devices with one remote but often works inconsistently with Hisense TVs.
IR sensor failures can prevent the TV from receiving signals from the remote control entirely, necessitating the use of the physical buttons on the TV itself for operation.
To resolve remote control and input issues:
- Replace the batteries in the remote control
- Remove any obstructions between the remote and the TV’s IR sensor
- Reset the remote by removing batteries and holding down the power button for 15 seconds
- Check and reseat all HDMI and other input connections
- Power cycle both the TV and any connected external devices
- Disable and re-enable CEC functionality through the TV settings menu
“Remote control problems are often mistaken for more serious TV malfunctions,” says consumer electronics reviewer Mark Johnson. “I’ve seen customers ready to replace entire televisions when the issue was simply a failing remote that could be replaced for under $20.”
Replacement remote controls for Hisense TVs are widely available, ranging from exact OEM replacements to universal remotes programmed to work with Hisense models. Original replacement remotes typically cost between $15-30, while universal options can be found for as little as $10.
If the issue persists with multiple remotes, the problem likely involves the TV’s IR sensor or main control board, which would require professional repair.
Hardware Failure Points and Lifespan Issues
Beyond the five most common problem categories, Hisense TVs may experience more serious hardware failures that affect their overall reliability and lifespan.
Panel defects including dead pixels, color uniformity issues, and screen burn-in occur in a small percentage of Hisense TVs. These problems are often present from manufacturing but may develop over time with usage.
Main board failures represent a serious issue that typically requires professional repair or complete replacement. Symptoms include failure to power on, stuck bootup screens, or erratic behavior across all functions.
Backlight array failures are particularly common in older Hisense models, with LEDs burning out progressively and creating uneven illumination, dark spots, or eventually complete picture loss with only sound remaining.
Capacitor degradation on the power board occurs as TVs age, leading to power instability, random shutdowns, or failure to power on. This issue becomes more common after 2-3 years of regular use.
To maximize the lifespan of your Hisense TV:
- Ensure adequate ventilation around the TV to prevent overheating
- Use surge protectors to guard against power fluctuations
- Turn off the TV when not in use rather than leaving it in standby mode
- Keep the TV in a temperature-controlled environment away from extreme heat or cold
- Clean vents periodically to prevent dust accumulation
- Avoid keeping static images on screen for extended periods to prevent burn-in
“Most Hisense TVs are designed with a projected lifespan of approximately 40,000-60,000 hours of use,” explains electronics engineer James Tan. “However, component failures often occur much earlier, particularly with power supply components and backlighting systems.”
For serious hardware failures, replacement parts are available online through electronics suppliers. Complete replacement kits containing power boards, main boards, and T-Con boards for common Hisense models typically cost between $50-100, such as this Television Repair Kit for Hisense 65R6E3
The cost-effectiveness of repairs versus replacement depends on the TV’s size and age. For larger models (55″ and above), professional repairs often make economic sense, while smaller or older models may be more economically replaced entirely.
Warranty and Customer Support
Understanding Hisense’s warranty coverage and customer support options is essential when dealing with TV problems that may require professional intervention.
Standard warranty coverage for most Hisense TVs in North America is limited to one year for parts and labor. This covers manufacturing defects but excludes physical damage or issues resulting from improper installation or usage.
Extended warranty options are available at the time of purchase, typically extending coverage to 3-5 years for additional cost. These plans often include enhanced support options and in-home service for larger models.
Customer support experiences vary widely among Hisense owners. Some report helpful and efficient service, while others describe frustrating experiences with long wait times and difficulty reaching knowledgeable representatives.
Repair authorization processes can be cumbersome, with many users reporting requirements to provide proof of purchase, detailed problem descriptions, and sometimes even photo or video evidence of issues before repairs are approved.
If you need to contact Hisense customer support:
- Have your model number, serial number, and proof of purchase ready
- Document the specific problems you’re experiencing in detail
- Take photos or videos demonstrating the issue when possible
- Be prepared to perform basic troubleshooting steps with the representative
- Request case numbers for all interactions to streamline follow-up communications
“Hisense has been working to improve their customer service experience in recent years, However, they still lag behind premium brands like Samsung and Sony in terms of support responsiveness and overall warranty satisfaction.”
For out-of-warranty repairs, Hisense typically directs customers to authorized service centers. Repair costs vary significantly based on the specific issue, with simple repairs starting around $75 and more complex problems like panel replacements potentially exceeding $400.
Some users find more cost-effective solutions through independent repair shops or DIY repairs using parts from suppliers like TV Parts Today or similar electronics parts retailers.

Frequently Asked Questions
How do I fix a Hisense TV with a black screen but has sound?
A Hisense TV with sound but no picture typically indicates either a backlight failure or T-Con board issue. First, perform a power cycle by unplugging the TV for 60 seconds. Then, shine a flashlight at the screen at an angle, if you can faintly see images, the backlights have failed.
For temporary use, try performing a factory reset by locating the reset button (usually a small pinhole) on the back of your TV and pressing it for 15 seconds.
If these steps don’t work, the problem likely requires replacement of either the LED backlight strips or the T-Con board, which costs between $50-150 in parts plus labor.
Why does my Hisense TV keep turning off and on by itself?
Random power cycling in Hisense TVs is typically caused by power supply instability, overheating, or software glitches. Start troubleshooting by disabling any sleep timers or power-saving features in your TV’s settings menu. Next, ensure your TV has adequate ventilation to prevent overheating.
If the problem persists, perform a factory reset by pressing the pinhole reset button on the back of your TV for 15 seconds. For many models, particularly in the R6 series, this issue often points to a failing power supply board, which can be replaced for approximately $30-50 plus labor if you’re not comfortable performing the repair yourself.
How long do Hisense TVs typically last before developing problems?
Hisense TVs generally provide trouble-free operation for 3-5 years, though this varies significantly based on usage patterns and model. The most durable components are the display panels themselves, while power supply boards and backlighting systems typically fail first.
“Heavy users who keep their TVs on for 8+ hours daily may notice problems emerging within 2-3 years, particularly backlight dimming or power instability.
To maximize your TV’s lifespan, use surge protectors, ensure adequate ventilation, and avoid leaving static images on screen for extended periods. While Hisense TVs may develop issues sooner than premium brands, their lower initial cost often still provides good overall value even accounting for potential repairs.
