If you’ve landed on this page, you’re probably experiencing the infuriating dilemma of your Hisense TV’s brightness acting up. I feel your pain; I’ve been there, and it can be frustrating.
But fret not, because I’ve got some insights to share on why Hisense TV brightness keeps changing and how I managed to fix this issue.
Why does my Hisense TV’s brightness keep changing on its own?
Before diving into solutions, it’s essential to understand why your Hisense TV’s brightness fluctuates like a rollercoaster. This unpredictable brightness issue can occur for a variety of reasons:
Ambient Light Sensor (ALS): Hisense TVs come equipped with an Ambient Light Sensor that automatically adjusts screen brightness based on the light in your room. This is usually great for energy-saving but can sometimes get a bit too sensitive.
Software Glitch: Software bugs or updates can occasionally mess with the TV’s settings, causing irregular brightness changes.
HDMI CEC Feature: If you have other devices connected to your TV through HDMI, they can send conflicting signals that affect the brightness.
Power Saving Mode: Hisense TVs offer power-saving features that can alter screen brightness to save energy.
Now, let’s get to the good part: How to fix it!
Fixing the Hisense TV Brightness Issue
1. Disable Ambient Light Sensor (ALS)
Step 1: Grab your Hisense TV remote.
Step 2: Press the “Settings” button.
Step 3: Scroll down to “Picture” settings.
Step 4: Find the “Ambient Light Sensor” or “Eco Sensor” option and turn it off.
Disabling the ALS will stop your TV from automatically adjusting brightness based on room lighting. This is a quick and effective fix if you prefer to set the brightness manually.
2. Check for Software Updates
Step 1: Again, press the “Settings” button on your remote.
Step 2: Navigate to “System” and select “Software Update.”
Step 3: If an update is available, follow the on-screen instructions to install it.
Updating the software can resolve potential bugs that might be causing the brightness fluctuations.
3. Disable HDMI CEC
Step 1: Access your TV’s settings as before.
Step 2: Go to “General” settings.
Step 3: Look for “HDMI CEC” or “Device Link” options and disable them.
Disabling HDMI CEC can prevent external devices from sending conflicting signals that affect your TV’s brightness.
4. Adjust Power Saving Mode
Step 1: One more time, press the “Settings” button.
Step 2: Head to “General” settings.
Step 3: Find “Eco” or “Power Saving Mode” and customize it to your liking.
Tweaking the power-saving settings can help maintain a more consistent brightness level.
