A common issue that many users encounter is a blurry horizontal screen. This can be annoying and affect your user experience. However, there’s no need to worry too much because this issue can be resolved with a number of solutions. In this article, FPT Shop will help you understand the causes of a blurry horizontal screen and share some ways to fix it.

The causes of a blurry horizontal screen

There are several reasons for a phone screen to be blurry horizontally. Specifically:

• LCD screen malfunction: Some pixels on the LCD screen may be dead or not functioning properly, resulting in a blurry horizontal screen.
• Damaged screen cable: The screen cable is the component that transmits signals from the motherboard to the screen. If the cable is cracked, damaged, or not properly connected, it can cause a blurry horizontal screen.

• External interference: Some electronic devices such as smartphones, speakers, or uncertified devices can cause interference and result in a blurry horizontal screen on the phone.
• Operating system or application errors: Occasionally, there may be conflicts between software or application errors on the phone’s operating system that can cause a blurry horizontal screen.
• Uncertified software or viruses: Malicious software installed from outside sources can invade the phone and cause screen issues, including blurry horizontal lines.

How to fix a blurry horizontal screen

There are several causes of a blurry phone screen, and the following solutions can temporarily help you fix this issue:

Restart the phone

Restarting the phone is a simple step but often effective in addressing minor screen-related issues. When you restart your phone, the operating system and applications will be reloaded, helping to resolve temporary errors or software conflicts that may cause a blurry horizontal screen.

Follow these steps:

• Press and hold the Power button on the smartphone to bring up the menu. Usually, this button is located at the top or side of the device.
• Next, select the “Restart” or “Shutdown” option. Confirm once again by pressing the “OK” or “Yes” button.
• After the phone is completely turned off, restart it and check if the issue has been resolved.

Check and clean the screen

To check and clean the phone screen, you can follow these methods:

Step 1: Ensure that the phone is turned off to ensure safety and avoid damage to the device.

Step 2: Use a soft and gentle cloth to clean the screen. Avoid using abrasive materials such as paper or fabric with hardness to prevent scratching the screen.

Step 3: Apply a small amount of distilled water or screen cleaning solution to the cloth and gently clean the screen. Make sure you don’t use too much water to avoid excessive moisture on the screen.

Step 4: If there are stubborn stains on the screen, you can try cleaning them with the following method:

• Use a soft, dry cloth to gently wipe off the dirt.
• If the stain remains, try using a small amount of screen cleaning solution or 70% isopropyl alcohol solution and gently wipe the stain.
• Avoid using solutions containing ammonia, gasoline, or strong cleaning agents, as they can damage the screen.

Check the screen cable connection

The screen cable is the component that connects the screen to the motherboard of the phone. If the screen cable is loose or not connected properly, it can cause a blurry horizontal screen. To check and reconnect the screen cable, you can follow these steps:

Step 1: Turn off the phone

Before starting to check and reconnect the screen cable, turn off the phone to ensure safety and avoid damage to the device.

Step 2: Disassemble the phone

Use appropriate tools (such as a plastic pick or small screwdriver) to open the phone and access the screen and motherboard section.

Step 3: Locate the screen cable

Find and identify the screen cable, which is a flat ribbon cable that connects the screen to the phone’s motherboard. Usually, this cable has one end fixed to the motherboard and one end plugged into the screen.

Step 4: Check the screen cable connection

Check the connection of the screen cable at both ends. Make sure the cable is firmly plugged into the corresponding ports on the screen and motherboard. If the cable feels loose, push it into the port securely.

Step 5: Clean the screen cable

If the screen cable is dirty or dusty, use a clean, soft cloth to gently wipe it. Avoid using strong cleaners or solvents as they can damage the screen cable.

Step 6: Reconnect the screen cable

After checking and cleaning, connect the screen cable to the corresponding ports on the screen and motherboard. Check once to ensure that the cable is securely plugged in and not loose.

Step 7: Reassemble the phone

After reconnecting the screen cable, proceed to reassemble the smartphone components in the correct order.

Step 8: Power on the phone and check

Check the screen from different angles, such as top to bottom, bottom to top, left to right, and vice versa. Observe carefully from different directions to ensure that the blurry horizontal screen issue has been completely resolved.
