Troubleshooting Hisense TV Flickering
Hisense TV flickering can disrupt your viewing experience. Addressing this issue involves a few key steps, including checking the HDMI cable and adjusting the refresh rate.
HDMI Cable Check
One common cause of flickering is the HDMI cable. Ensuring that this cable is properly connected and functioning can often resolve the flicker issue (PCGuide).
- Check Connection: Unplug the HDMI cable from both the TV and the external device. Reconnect it tightly to ensure a firm connection.
- Inspect the Cable: Look for any visible damage to the HDMI cable. Try using a different cable if possible.
- Change Ports: If your TV has multiple HDMI ports, try connecting the cable to a different port on your Hisense TV.
If the issue persists, refer to our guide on fixing Hisense TV screen flicker for additional troubleshooting steps.
Refresh Rate Adjustment
Adjusting the refresh rate can also mitigate flickering issues. The refresh rate should match the capabilities of your Hisense TV and the connected device (ScreenCloud). Here’s how:
- Access Settings: Use your TV remote to navigate to the settings menu.
- Find Refresh Rate Settings: Depending on your TV model, this may be under “Picture Settings” or “Advanced Settings.”
- Adjust Refresh Rate: Set the refresh rate to 60Hz, which is often a reliable setting for most HDMI-connected devices.
Below is a table summarizing the supported refresh rates for different HDMI versions:
| HDMI Version | Max Refresh Rate (1080p) | Max Refresh Rate (4K) |
|---|---|---|
| HDMI 1.4 | 60Hz | 30Hz |
| HDMI 2.0 | 60Hz | 60Hz |

Resolving Hisense TV Blinking Issues
When experiencing blinking issues with Hisense TVs, two primary areas to examine include the power supply and firmware updates. Here’s how to diagnose and address these issues effectively.
Power Supply Analysis
Blinking red lights on a Hisense TV often point to power supply issues. These can stem from a faulty power cord, internal power board problems, or a malfunctioning surge protector.
To analyze the power supply:
- Inspect the Power Cord: Ensure that the power cord is securely connected to both the TV and the outlet. Look for any visible damage to the cord.
- Check the Surge Protector: If using a surge protector, make sure it is functioning correctly. Test the TV by plugging it directly into the wall outlet.
- Power Cycle the TV: Disconnect the TV from the power source, wait 30 seconds, and then plug it back in. This can reset the internal power board.
- Internal Power Board Check: If the issue persists, the internal power board might be faulty. In this case, professional repair or replacement may be necessary.
Firmware Update
Firmware updates are essential for maintaining the proper functionality of your Hisense TV. Outdated firmware can cause various issues, including blinking and flickering screens.
To update the firmware:
- Check for Updates: Navigate to the TV’s settings menu, and look for firmware updates. This option is usually found under the “Support” or “System” section.
- Download and Install: If an update is available, follow the on-screen instructions to download and install it. Ensure your TV remains connected to a stable internet connection during this process.
- Factory Reset: If updating the firmware doesn’t resolve the issue, consider resetting the TV to factory settings. This drastic step will erase all data and settings but can resolve persistent problems (All About Hisense).

Addressing Hisense TV Horizontal Lines
Horizontal lines on a Hisense TV can be a frustrating issue. These lines can manifest as static, flickering, or scrolling bars across the screen and can result from either software glitches or hardware failures. Understanding the cause is key to finding the right solution.
Software vs. Hardware Causes
Horizontal lines on a Hisense TV can be due to various reasons, ranging from minor software hitches to severe hardware malfunctions. It’s important to differentiate between these causes to apply the correct fix.
| Cause Type | Characteristics |
|---|---|
| Software | Lines appear intermittently or temporarily and may disappear after a reset or update. Often linked to minor glitches and can be solved through troubleshooting steps. |
| Hardware | Persistent lines that remain visible regardless of input source or settings changes. Indicate a more severe problem related to physical components like the display screen or LED modules. |
Temporary lines often result from software issues. These can frequently be resolved by resetting the TV or performing a firmware update. Hardware problems, on the other hand, cause persistent lines that don’t change with input or settings. They often require professional repair or component replacements.

Hisense TVs often have hidden diagnostic modes that can provide additional information for troubleshooting horizontal line issues. These modes can help identify if the problem is related to the firmware or other software configurations. To update your firmware, follow these steps:
- Go to Settings: Navigate to the settings menu on your Hisense TV.
- Select Support: Find and select the “Support” option.
- Choose Software Update: Click on the “Software Update” option.
- Check for Updates: Select “Check Firmware Update” to see if there are any new updates available.
- Update if Available: If an update is available, follow the on-screen instructions to download and install it.
Ensuring your TV’s firmware is current can help eliminate or reduce horizontal line issues, improving your viewing experience. For more tips on updating firmware and resolving other TV issues, see our how to fix Hisense TV flickering guide.

Fixing Hisense TV Screen Flicker
Backlight Control Analysis
Screen flicker in modern televisions is often caused by the way the TV’s backlight is controlled, specifically through a method known as Pulse Width Modulation (PWM). PWM can create a strobing effect that may lead to eye strain over extended periods (TV Parts Today). To analyze and potentially fix this issue, one could:
- Check the television’s backlight settings in the menu and try different levels.
- If available, adjust the PWM frequency settings to reduce flicker.
- Look for firmware updates that could address known flickering issues.
Consulting the TV manual or the manufacturer’s website can provide specific instructions for your model. For more detailed analysis of backlight issues, read our article on unlocking Hisense TV screensaver potential.
Adjusting Picture Settings
In addition to backlight control, adjusting the picture settings on your Hisense TV might help alleviate screen flicker problems. This is especially relevant when the TV is connected to a PC via HDMI (ScreenCloud).
To troubleshoot and adjust picture settings:
- Brightness: Lower or increase the brightness setting to see if the flickering is reduced.
- Contrast: Adjust the contrast settings to find a comfortable viewing level.
- Color Settings: Modify the color settings that might be causing stress on the screen.
- Refresh Rate: Ensure the refresh rate is set to a level compatible with the connected device (usually 60 Hz is standard for TVs).
| Setting | Default Value | Recommended Adjustment |
|---|---|---|
| Brightness | 50 | 40 – 60 |
| Contrast | 50 | 40 – 60 |
| Color | 50 | 45 – 55 |
| Refresh Rate | 60 Hz | 60 Hz – 120 Hz |
