How to Fix Vertical Lines on Sharp TV Screen
Follow these troubleshooting methods in chronological order to make the process simple.
Check the Power Supply
First, inspect the power supply to your TV. An excessive or unstable power supply might affect the TV’s internal components and ultimately cause vertical lines on your Sharp TV. Connect the TV’s power cable to a different wall outlet or connect the cable to the surge protector. Then, turn on your Sharp TV and look for the vertical lines. If the issue persists, move on to the next fix.
Power Cycle the Sharp TV
Start by detaching the power cord from the socket and leave it disconnected for a few minutes. Locate the power button on your Sharp TV, typically found at the bottom or rear of the device. Hold down the Power button for about thirty seconds to drain any remaining power completely. After waiting, reconnect the TV cord and switch on your Sharp TV.
Performing a power cycle often resolves vertical line problems on Sharp TVs. If the issue persists after trying this, try the next troubleshooting technique.
Connect Cable to a New Port
Ensure the HDMI cables connecting to your TV are not damaged and securely plugged into the HDMI port. If you notice any damage to the cable, switch to a new HDMI cable. If the cable seems fine or if you don’t find any issues, try using a different HDMI port on your TV. Once you have inspected the cables and ports and ensured they are in good condition, proceed to check the TV input settings.
Change the TV Input
Check if you have chosen the appropriate input using the remote control. Once selected, ensure the external cables are firmly connected. If the vertical lines are still showing, the problem may be with the TV’s HDMI port. Disconnect and connect the external device to a different port. Then, change the Sharp TV input to the respective HDMI you have plugged in. If it doesn’t work, try the next solution.
Update the Sharp TV Firmware
Updating the Sharp TV firmware is another reliable way to fix picture-related issues such as vertical lines. Ensure your Sharp TV is connected to stable WiFi and check whether you have missed any firmware updates. After completing the update, restart the Sharp TV to get the latest version and check if the vertical lines issue is resolved.
Factory Reset Sharp TV
If the vertical lines appear after restarting, it is better to perform a hard reset on your Sharp TV. This process permanently deletes all your data, including the installed apps, watch history, and account info. After resetting, check whether a vertical line problem is resolved. If you still have this issue, jump into the next troubleshooting technique.
Check for Hardware Damages
In most cases, vertical lines occur on your Sharp TV due to the defective T-con board or LCD Panel tab bonds. Both these parts are responsible for displaying pictures on the screen. If there is any damage on these parts, you will see vertical lines on the Sharp TV screen. You need the help of a technician to repair or replace the parts. Instead of contacting unauthorized service centers, you should contact the Sharp customer support team to get a reliable solution.
