Have you noticed an annoying blue tint or hue covering the screen of your Hisense TV? This common issue can be frustrating, but is usually easy to resolve with a few quick troubleshooting steps.
As a tech specialist with over 10 years of experience repairing consumer electronics, I’ve helped countless customers fix blue tinted Hisense TV screens. In this comprehensive guide, I’ll outline the leading causes of the blue screen problem and walk you through solutions even a beginner can implement.
Overview: What Causes Blue Tint on Hisense TVs
Before jumping into the step-by-step game plan, it’s helpful to understand what underlying issue causes a blue hue or tint.
The blue tint stems from one of three core problems:
- Software glitch or firmware needing update
- Faulty/damaged HDMI input or cable
- Backlight LED failure
Let’s explore each one in more detail:
Software Issues Causing Blue Tint
Like any smart device, Hisense TVs rely on complex software to operate properly. Occasionally a minor software glitch leads to display abnormalities like blue tint. Restarting or resetting your TV essentially refreshes the software, clearing up any bugs as covered in this guide to fixing Hisense TVs that won’t turn on.
Restarting or resetting your TV essentially refreshes the software, clearing up any bugs.
Outdated firmware versions can also introduce problems, so updating to the latest firmware revamps device performance.
Input/Cable Issues Behind Blue Tinted Screen
At their core, televisions simply project the content from external devices like Blu-ray players, streaming sticks, or cable boxes.
If the HDMI cable connecting your device malfunctions or the TV’s HDMI port sustains damage, it can alter colors displayed.
Reseating cables often solves input issues leading to blue tint. Examining ports and replacing faulty HDMI cords restores proper signal transfer.
If your TV displays correct colors on startup but exhibits blue hue when streaming or gaming, it suggests input interference rather than internal TV failure. See this troubleshooting guide for Hisense TVs with no sound for help diagnosing connection issues.
Backlight Failure Creating a Blueish Image
Modern LCD displays utilize LED backlighting rather than old-fashioned CCFL backlights.
The LEDs emit blue light that passes through a yellow phosphor coating, creating bright white illumination for the screen.
But after thousands of hours of use, this yellow coating wears off, allowing blue light to tint on-screen colors. Replacing damaged LED strips resolves this.
Now let’s dive into the step-by-step game plan for troubleshooting and resolving a Hisense TV blue tint issue based on its underlying cause.
Step 1: Reset/Restart Your Hisense Smart TV
Begin troubleshooting by resetting your Hisense television, as minor software glitches often generate on-screen tinting.
Recycling power clears any corrupted data or firmware hiccups causing display issues. Best of all, restarting your TV only takes a minute.
Here is the quick process to reset power on your Hisense:
- Locate the power button on the side or back of television. Newer voice-enabled models feature a mic-mute button that also controls power functions.
- Press and hold this power button for 10-15 seconds until the TV fully shuts down.
- Unplug TV power cable from electrical outlet and wait 1 minute.
- Reconnect power cable, then turn TV on normally using remote or power button.
Upon restart, your Hisense TV blue tint may have disappeared completely.
If not, continue troubleshooting because the underlying cause likely relates to connection or hardware issues covered in subsequent steps.
Refreshing Hisense TV Firmware
Alongside resetting power, verify your television runs the latest firmware version. Outdated firmware often introduce software bugs yielding display problems.
Access firmware update menus through the settings cog icon on your Hisense television:
- Using remote, select the settings icon from your Hisense TV’s home screen menu.
- Choose “Support” option, then select “System Update” or similarly named choice.
- The menu displays current firmware version and automatically checks server for updates.
- If update available, select “Yes” to install newest firmware version.
Updating older firmware boosts stability and performance while squashing bugs causing issues like screen tinting.
Step 2: Inspect All Connected Devices and Cables
With software troubleshooting complete, turn attention to external devices and cables that could cause a Hisense blue tinted picture.
If your TV displays correct colors on startup but exhibits blue hue when streaming or gaming, it suggests input interference rather than internal TV failure.
Scan all devices transmitting content to your television, including:
- Game consoles
- Blu-ray/DVD players
- Streaming boxes like Roku or Firestick
- Cable/satellite box
- Computer monitor cable
Follow this systematic process inspecting connections:
- Power down television – Unplug all devices from power sources prior to disconnecting.
- Label cords – Organize cables by taping labels near each end indicating connected device. e.g. “Blu-ray player”.
- Photograph setup – Take photos of existing cable setup from both the front and rear of devices so you can replicate the original configuration.
- Disconnect HDMI cords – Unplug all HDMI cables from rear of television. Coaxial cables can remain plugged in.
- Inspect TV ports – Shine flashlight inside HDMI input ports on the television, checking for broken/bent pins or debris/damage. If ports appear cracked or pins crooked, contact Hisense Support about replacing defective HDMI inputs.
- Check cable tips – Similarly examine the metal tips of disconnected HDMI cords for cracked plastic housings or twisted metal pins. Faulty cables require replacement.
- Reconnect HDMI devices – Firmly reinsert HDMI cords back into original television input ports according to your labeling system and photos. Triple check connections feel snug.
- Eliminate sources individually – Turn television back on and reconnect devices ONE-BY-ONE. Between testing each external component, check if blue tint persists onscreen. If tint disappears upon removing a particular device, investigate cable connections or try updating device firmware.
This systematic inspection often exposes the root cause of Hisense TV blue tint — a faulty HDMI cable or malfunctioning media player/cable box introducing display errors. Reseating connections helps too.
Searching for input interference only takes about 15-20 minutes and costs nothing. If blue hue persists onscreen regardless of connected devices, backlight issues likely cause the problem instead.
Step 3: Adjust Color Profile and Blue Channel Settings
Before delving into complex backlight repairs, attempt software tweaks correcting color balance on your Hisense television.
Modern televisions allow extensive image customization, including directly manipulating color channels delivering blue hues responsible for unwanted tinting.
Access the color management menus from picture settings on your Hisense television remote.
Here are the steps for adjusting color channel settings:
- Press “Menu” button on Hisense remote to bring up main television settings
- Select “Picture” option, then choose “Expert Settings” submenu
- Open “Color Tuner” selection with RGB slider adjustments
- Drag blue channel setting left toward minus sign (-) to reduce blue intensity
- Test different blue slider positions to minimize blue tint presence
Lowering blue channel delivery potentially counters a blue tint without resetting television. However, color distortion may persist if backlights emit primarily blue wavelengths.
Continue tweaking color temperature and blue slider settings to combat less severe cases of blue tinting on the Hisense TV display.
Step 4: Factory Reset Hisense Smart TV
If you’ve worked through input devices, cables, ports, and color settings without resolving blue hue, consider factory resetting your Hisense Smart TV as a last resort software fix.
Factory reset erases all user data and customizations, reverting television software back to original out-of-box state. Resetting deletes stored bugs that alter color display.
On modern voice assistant-capable Hisense TVs manufactured after 2018, you can factory reset using buttons on the TV itself rather than remote control.
Here are simplified steps to factory reset Hisense televisions with/without remote as outlined in this step-by-step walkthrough for resetting your Hisense TV.
Factory Reset Using Hisense TV Remote
- Press “Home” button on remote to open Smart TV settings
- Select the “Settings” gear icon, then choose “Device Preferences”
- Scroll down to the bottom “Reset” option
- Confirm factory reset prompt by choosing “Reset” again
Factory Reset Without Hisense Remote
- Unmount TV from wall to access rear panel
- Locate small “Reset” pinhole button on the lower backside
- Straighten paperclip into makeshift reset tool
- Push pin inside “Reset” hole for 10+ seconds until TV restarts itself
Once your Hisense TV completes factory reset process, rerun channel scans and reconnect streaming/cable devices.
Hopefully the fresh software install clears all prior display issues. But if a stubborn blue tint remains visible, investigate backlight fixes covered next.
Step 5: Replace Defective Backlight LED Strips
The Hisense TV blue tint fix journey culminates with backlight inspection and rejuvenation.
As outlined earlier, degraded or burned out LEDs frequently cause color temperature imbalance and blue hue.
Fortunately, opening the TV to access and replace LED strips only requires a Phillips screwdriver and small flathead tool. With a minor investment of time and about $65 for replacement parts, you can often resolve backlight issues yourself rather than paying $250+ for professional TV repair costs.
Review this condensed overview of do-it-yourself Hisense LED backlight replacement:
LED Backlight Replacement Process
- Unplug television power cord and carefully place screen-down on a soft, clean surface.
- Using Phillips screwdriver, remove all rear cover screws from plastic backing. Set aside intact for reassembly.
- Starting at bottom edge corners, carefully pry off rear cover using a small flathead screwdriver. Work slowly around perimeter to avoid cracking plastic.
- Upon removing rear shell, you’ll see metal framework and circuit boards housing LED strips mounted along bottom edge.
- Referencing part numbers stamped onto circuit boards, purchase compatible LED strip replacements on Amazon or DigiKey for about $12 per strip.
- Unscrew defective LED strips and unplug wiring harness connectors. Match part numbers to new replacement strips.
- Connect harness plugs to updated strips. Secure metal mounting brackets using original screws.
- Test illumination of new backlights by temporarily reconnecting rear cover and power cord. Power on TV and check for blue tint.
- Seeing normal colors again, fully reassemble metal housing and plastic shell. Reinsert all perimeter screws carefully to avoid cracking case.
Take precautions against electrocution and LED eye damage when operating on open televisions. Work slowly and double check connections to avoid mistakes that may cause a blinking red light on your Hisense TV indicating errors.
But implementing a DIY solution typically beats the high expense and delayed timing of TV repair shops. And it strengthens your repair skills.
