<\/span><\/h3>\n\n\n\nNext, check your HDMI cable and port.<\/p>\n\n\n\n
A loose or damaged HDMI cable or port can disrupt the data flow between the TV and the external device, causing display issues like a half-black screen.<\/p>\n\n\n\n
Step 1: Power off the TV<\/strong><\/p>\n\n\n\n <\/figure>\n\n\n\nStep 2: Inspect the HDMI cable<\/strong><\/p>\n\n\n\nExamine the HDMI cable connected to the TV and the external device.<\/p>\n\n\n\n
Look for any visible damage like bends, cuts, or fraying.<\/p>\n\n\n\n
Step 3: Disconnect and reconnect<\/strong><\/p>\n\n\n\nCarefully unplug the HDMI cable (from both the external device and the TV).<\/p>\n\n\n\n
Then, securely plug it back into both ends.<\/p>\n\n\n\n
Step 4: Use a different HDMI port<\/strong><\/p>\n\n\n\nIf your TV has multiple HDMI ports, try switching to a different one.<\/p>\n\n\n\n
Sometimes, a specific port might have issues.<\/p>\n\n\n\n
Step 5: Power on the TV and device.<\/strong><\/p>\n\n\n\nIf the half-black screen problem occurs due to the HDMI cable and port, now your TV can work again.<\/p>\n\n\n\n
<\/span>Method 5: Try A Picture Test<\/strong><\/span><\/h3>\n\n\n\nThis test helps identify whether the issue is intrinsic to the TV or external factors, specifically:<\/p>\n\n\n\n
\nIf the TV displays content correctly during this process but not with the source, the problem could be the source device, the cable, or the settings.<\/li>\n\n\n\n If the issue persists even during the picture test, it’s a problem with the TV.<\/li>\n<\/ul>\n\n\n\nFollow these steps for this test:<\/p>\n\n\n\n
Step 1: Go to Settings.<\/strong><\/p>\n\n\n\nStep 2: Navigate to “Device Care.”<\/strong><\/p>\n\n\n\nStep 3: Select “Self Diagnosis.”<\/strong><\/p>\n\n\n\nStep 4: Choose “Picture Test.”<\/strong><\/p>\n\n\n\nStep 5: Confirm your selection by clicking “OK.”<\/strong><\/p>\n\n\n\nStep 6: Examine the picture displayed.<\/strong><\/p>\n\n\n\nYou can respond with “Yes” if the picture is normal, “No” if there’s a problem, or “Show again” for another view.<\/p>\n\n\n\n
If you own an older version of the TV ( 2021 and earlier), follow these steps to test it:<\/p>\n\n\n\n
1\/ Access Settings on your TV.<\/p>\n\n\n\n
2\/ Proceed to “Support” and select “Self Diagnosis.”<\/p>\n\n\n\n
3\/ Choose “Picture Test” and follow the on-screen instructions.<\/p>\n\n\n\n
By carrying out this test, you’ll know whether the TV is causing this problem or if external factors are to blame.<\/p>\n\n\n\n
Then, you can decide on the appropriate troubleshooting steps or repairs needed.<\/p>\n\n\n\n
<\/span>Method 6: Reset Picture Settings<\/strong><\/span><\/h3>\n\n\n\nSometimes, incorrect picture settings can cause display anomalies. Here’s how to go about it:<\/p>\n\n\n\n
Step 1: Access Picture Settings<\/strong><\/p>\n\n\n\nUse your Samsung TV remote control to navigate to Settings.<\/p>\n\n\n\n
Then, scroll through the settings options and choose the Picture option.<\/p>\n\n\n\n
Step 2: Find and select Expert Settings.<\/strong><\/p>\n\n\n\nStep 3: Scroll down until you locate the Reset Picture option.<\/strong><\/p>\n\n\n\nNote:<\/em><\/strong> If this option is gray, ensure you don’t have any apps running in the background.<\/em><\/p>\n\n\n\nStep 4: Confirm the reset<\/strong><\/p>\n\n\n\nStep 5: TV restart<\/strong><\/p>\n\n\n\nAfter confirming the reset, your TV will restart. It’s normal and part of the process.<\/p>\n\n\n\n
Resetting the picture settings can help eliminate incorrect settings that might cause display issues like a half-black screen.<\/p>\n\n\n\n
If the problem was due to settings misconfigurations, this method should rectify it.<\/p>\n\n\n\n
<\/span>Method 7: Update System Software<\/strong><\/span><\/h3>\n\n\n\nI usually use this method if the above methods do not solve the problem.<\/p>\n\n\n\n
Besides fixing the half-black screen, software updates often include bug fixes and improvements that can resolve display-related issues.<\/p>\n\n\n\n
Step 1: Access System Settings<\/strong><\/p>\n\n\n\nStep 2: Find System Software Update<\/strong><\/p>\n\n\n\nLook for \u201cSoftware Update\u201d within the settings menu.<\/p>\n\n\n\n
It might be under “General” or a similar category.<\/p>\n\n\n\n
Step 3: Check for Updates<\/strong><\/p>\n\n\n\nSelect \u201cSoftware Update\u201d and then choose “Check for Updates.”<\/p>\n\n\n\n
Your TV will now search for any available updates.<\/p>\n\n\n\n
Step 4: Install available Updates<\/strong><\/p>\n\n\n\nIf there’s an update, follow the on-screen prompts to install it.<\/p>\n\n\n\n
Your TV might need to restart during this process.<\/p>\n\n\n\n
Then, allow the TV to complete the installation of the updates.<\/p>\n\n\n\n
Step 5: Restart TV<\/strong><\/p>\n\n\n\nAfter installing the updates, your TV might prompt you to restart it.<\/p>\n\n\n\n
If not, you must manually power off and then power on the TV.<\/p>\n\n\n\n
<\/span>Method 8: Reset To Factory Settings<\/strong><\/span><\/h3>\n\n\n\nResetting to factory settings essentially wipes out any customized settings and returns your TV to its original state when you first purchased it.<\/p>\n\n\n\n
So it can help eliminate complex software issues.<\/p>\n\n\n\n
Step 1: Access Settings<\/strong><\/p>\n\n\n\nStep 2: Reset<\/strong><\/p>\n\n\n\nLook for the General or Support category within the settings menu.<\/p>\n\n\n\n
Inside this section, find the option labeled “Reset” or “Factory Reset.”<\/p>\n\n\n\n
Then, choose this option to initiate the process.<\/p>\n\n\n\n
A confirmation message will appear, warning that it’ll erase all settings. Confirm that you want to proceed.<\/p>\n\n\n\n
Step 3: Enter the security PIN<\/strong><\/p>\n\n\n\nIf prompted, enter the security PIN for your TV.<\/p>\n\n\n\n
The default is often “0000” unless you’ve changed it.<\/p>\n\n\n\n
Once confirmed, the TV will begin the factory reset process in a few minutes.<\/p>\n\n\n\n
Note<\/em><\/strong>: This action will erase all your settings and installed apps.<\/em><\/p>\n\n\n\n<\/span>Method 9: Replace The Backlight Strips<\/strong><\/span><\/h3>\n\n\n\nNext, I’ll guide you through replacing the backlight strips.<\/p>\n\n\n\n
This method addresses hardware-related problems that might be causing the uneven display.<\/p>\n\n\n\n
But I recommend taking these steps only if you have the knowledge and technique of repairing electronic devices.<\/p>\n\n\n\n
Here’s what you need to do:<\/p>\n\n\n\n
Step 1: Turn off and unplug<\/strong><\/p>\n\n\n\nEnsure your TV is turned off and unplugged from the power outlet to ensure your safety.<\/p>\n\n\n\n
Step 2: Remove the bezel<\/strong><\/p>\n\n\n\nGently remove the frame (bezel) around the TV screen.<\/p>\n\n\n\n
This step involves unscrewing screws or using a plastic pry tool to pop off the bezel.<\/p>\n\n\n\n
Step 3: Access the backlight strips<\/strong><\/p>\n\n\n\nOnce the bezel is off, access the backlight strips. These are usually behind the screen panel.<\/p>\n\n\n\n
Step 4: Detach old backlight strips<\/strong><\/p>\n\n\n\nCarefully detach the old backlight strips from their connectors. Take note of their positions and connections.<\/p>\n\n\n\n
Step 5: Attach new backlight strips<\/strong><\/p>\n\n\n\nConnect the new backlight strips in the same positions as the old ones.<\/p>\n\n\n\n
Step 6: Reassemble<\/strong><\/p>\n\n\n\nPut the bezel back on and secure it in place. Make sure you tighten all screws and align the frame.<\/p>\n\n\n\n
