Methods to Fix the Horizontal Lines on Sharp TV Screen
When an issue arises, you can try power cycling as a primary fix. However, if these methods fail to resolve the problem, you can follow the advanced techniques below.
Power Cycle the Sharp TV
Temporary glitches and bugs can cause horizontal lines to appear on the Sharp TV screen. You can manually reboot the Sharp TV to get rid of the bugs and glitches.
1. Disconnect the power cord of your Sharp TV from the wall socket while it is still turned on.
2. After unplugging, locate the Power button at the bottom or backside of the TV.
3. Long-press the Power button for 30 seconds to discharge any remaining power from the TV. This will perform a power cycle on your TV.
4. After a few minutes, reconnect the power cord to the outlet and power on your Sharp TV.
In many cases, this technique resolves the issue. However, if the problem persists, move to the next troubleshooting method.
Check the Power Supply
If there are any power fluctuations, your TV won’t receive an adequate supply to power up. The standard reason for the low voltage is faulty surge protectors. So, detach the TV cord from the outlet and remove the surge protectors from the wall socket. Connect your TV cord directly to the wall socket and check if it works.
Check the Connected Cables on the Sharp TV
Cables play an important role in flawless TV streaming. However, if the cable is loosened or damaged, horizontal lines will appear on your TV screen.
- Examine the cable quality if you’re utilizing an external device to stream content on your TV.
- Detach the cables from the TV and inspect for any damage.
- If you find any damage within the cables, replace them with new ones.
After changing the cables, check if the issue has been resolved. If it stays, try the next solution.
Inspect the Sharp TV Inputs
It is important to connect the cable to your Sharp TV’s port firmly. Otherwise, the loose connection will cause the content to flicker or display horizontal or vertical lines. To fix this, eject the connected cable, wait a few minutes, and reattach them to the port properly. If the issue stays the same, try the next workaround.
Update the Sharp TV Using a USB
If you forget to update your Sharp TV, it will create issues. Updating your Sharp TV is mandatory because updating the firmware will fix all the technical errors associated with it. If you can’t upgrade the Sharp TV software via settings, use a USB drive to update it manually.
1. Visit the Sharp Product Downloads page on your desktop or PC.
2. Enter the required details in the field and click the Next button.
3. Download and extract the Software ZIP file and copy it onto the USB drive.
4. Now, insert the drive into your Sharp TV and press the Menu button.
5. Choose the Digital Setup option and click the Software Update (USB).
6. Enter your Sharp TV’s Model Number and input the Password.
7. Tap the Enter button and wait until your Sharp TV detects a USB drive.
Your TV will initiate the Software update and restart on its own, then select the Enter option to complete the process.
Hard Reset the Sharp TV
Another way to get rid of the horizontal lines is to reset the Sharp Smart TV to factory default settings. You can reset the Sharp TV using the steps below.
1. Disconnect your Sharp TV cord from the wall socket.
2. Perform the simultaneous action of pressing the Channel Down and Input buttons.
3. While keeping the buttons pressed, connect the Sharp TV to the power source.
4. If your Sharp TV is not turning on by itself, press the Power button to turn it on manually.
5. Navigate to the Service Mode menu using the TV’s Channel Up and Channel Down buttons to toggle between each menu.
6. Choose Factory Reset and confirm your action.
7. Now, follow the on-screen procedures to complete the reset process.
Keep in mind that resetting your Sharp TV will permanently erase all your data, and you will need to set up your Sharp Smart TV from the beginning. You won’t be able to retrieve the lost data under any circumstances.
