Dealing with a TV screen that displays annoying lines can be frustrating, especially when you’re trying to enjoy your favorite shows or movies. These lines may be a sign of internal damage or a failure in the screen’s connections. Here’s a step-by-step guide on how to fix broken screen tv with lines, determine the cause of the problem and potentially fix it yourself before considering professional repairs or replacement.

How to Fix Broken Screen Tv With Lines?

Step 1: Diagnose the Problem

Check Connection Cables: First, inspect all HDMI and other connection cables to ensure they’re not loose, damaged, or faulty. Try replacing them with new ones to see if the issue resolves.
External Devices: Disconnect all external devices (like gaming consoles, DVD players, etc.) to rule out the possibility that the lines are being caused by one of these devices.

Step 2: Perform a Soft Reset

Power Cycle Your TV: Unplug your TV from the wall, wait for about one minute, and then plug it back in. This can reset the TV’s internal components and possibly eliminate the lines.

Step 3: Adjust Display Settings

Picture Settings: Go into your TV’s settings menu and adjust the picture settings such as contrast, brightness, and color. Sometimes, incorrect settings can cause display issues.
Software Update: Ensure your TV’s firmware is up to date. Manufacturers often release updates to fix bugs or other issues.

Step 4: Check for Physical Damage

Screen Examination: Carefully inspect the screen for physical damage. If there’s visible damage and your TV is under warranty, contact the manufacturer for repair or replacement options.

Step 5: Tinker with Internal Components (Advanced)

Re-seat Internal Cables: If you’re comfortable with electronics and your TV is out of warranty, you might consider opening the back panel of your TV to check for any loose internal connections. Re-seat any loose cables, especially those connected to the screen.
Check the T-Con Board: The Timing Control Board (T-Con Board) is often responsible for addressing rows and columns on LCD TV screens. If this board is faulty, it could result in horizontal or vertical lines.

Step 6: Seek Professional Help

If none of the above steps work, it’s likely that the issue is more serious (like a damaged LCD panel). In this case, consult a professional technician. Repairing a broken screen, especially if it involves replacing the LCD panel, can be almost as expensive as buying a new TV.

Prevention Tips

Surge Protection: Use surge protectors to safeguard your TV from voltage spikes.
Proper Handling: Always handle your TV with care. Avoid physical impacts or pressure on the screen.
Ventilation: Ensure your TV has proper ventilation to prevent overheating, which could lead to internal damage.

Fixing a TV with lines on the screen can sometimes be simple, but it often requires professional intervention, especially when dealing with internal hardware issues. Always consider the cost of repair versus replacement, particularly if your TV is older and might not be worth a costly repair.
