What Causes Samsung TV Half Screen Darker From One Side?
Numerous factors might contribute to a Samsung TV being dark on one side. The first possibility is that you accidentally switched off your TV or firmly yanked the cord out. Another cause might be if your Samsung TV software is outdated or if a foreign object comes between screen and backlight.
Also, if a child has been playing with the remote, there is a chance that the settings have been changed. If this is the case, you can reset the settings and get it back up and running.
Whatever the cause, here’s a comprehensive list of fixes to get your TV working again.
How to Fix Samsung TV Dark on One Side
You can fix your Samsung TV half-screen darker by power cycling your TV, updating your TV software, resetting the TV picture setting, changing the backlight, and disconnecting and reconnecting all cables. If none of these solutions works, you can factory reset the TV or contact Samsung Customer Service for assistance.
1. Disconnect and Reconnect All Cables
A cable that isn’t correctly positioned may cause your Samsung screen to appear partially dark.
What Causes the Cable Not to Function Properly
- Poor-quality cable
- Broken pins in the port
- Insufficient contact between cable and plug
It’s essential to inspect your cables regularly.
- Turn off the TV.
- Remove all physical cords attached to the TV’s back, including any HDMI cables.
- If you have access to any compressed air, you should use it to clean the contacts in the connection on the TV and those on the cable. Blow softly on them if you don’t have compressed air available.
- Push the cords firmly back into their ports on the TV.
- Turn the TV back on once again.
Try an alternative HDMI input if it doesn’t resolve the issue. Many TVs feature three or four HDMI ports. Try the one located in a different portion of the TV, if there is one, as it should not share a connection with the rest of the TV’s components in the main board.
Insert your HDMI cable into the new port, make a mental note of the number next to it, and then choose the appropriate HDMI input source on your TV. You can press the Input or Source button on your TV remote.
Besides that, you can disconnect all external components, including Bluetooth-enabled gadgets and any coaxial or signal cords, leaving the TV with only a power wire plugged.
Try connecting each HDMI cable and other cables back on the television one by one until you identify the faulty cable that you need to change.
2. Conduct a Picture Test
In the Settings section of every Samsung TV are self-diagnosing features. By using them, your TV will be able to report on any potential problems. Use this picture test tool to see if there are any immediately apparent problems with your TV.
Follow the guidelines below to conduct a picture test. Screen issues, such as white spots on a Samsung TV, are only one of several that Picture Tests can report.

This check should reveal screen issues that are simple to repair.
3. Reset the Picture Settings

At this point, we suggest restoring them to their factory settings.

4. Check for Foreign Object Between the Backlight and the Screen
If something is blocking the backlight from reaching your TV screen, a black shadow will appear on the screen. This can be dust or dirt, or perhaps a bug got lodged.
To examine whether anything obstructs your TV’s lighting, remove the screen. It usually only takes a screwdriver and a helping hand to complete this. We advise getting assistance from a skilled expert.
5. Power Cycle Your Samsung TV

6. Adjust Your TV’s Backlight Level
Today’s Samsung TVs provide a wide variety of visual modes. Choosing which settings to change might be challenging to solving your TV’s black screen issue.
To be more precise, consider lowering the lighting on your TV. Because if you reduce it, the LED lighting strips won’t be under as much stress. And in certain instances, this is sufficient to save some backlights from failure.
The steps to changing the lighting level on your Samsung TV are as follows:
