Identifying the Issue
Types of Screen Issues
Screen issues can often manifest in various ways, one common problem being the appearance of horizontal lines on the screen. Specific issues include:
- Odd colors on the screen, with the screen displaying mostly yellow, gray, red, blue, or purple hues.
- Horizontal lines appearing across the screen.
- The screen displaying abnormal or distorted colors (Sony Support).
Different symptoms might indicate different underlying problems ranging from simple adjustments to more serious hardware issues.
Troubleshooting Steps
When facing screen issues like horizontal lines on a Sony TV, here are some initial troubleshooting steps:
-
Check for Loose Ribbon Cables:
- Owners have noticed issues like dark sides of the screen, ghosting, and horizontal lines on older Sony Bravia models can stem from loose ribbon cables. Pressing along the top of the ribbon cables might temporarily fix the problem, but this is often not a permanent solution (iFixit).
-
Adjust Resolution Output:
- For some users, adjusting the TV’s resolution output to a lower HD setting has helped eliminate horizontal lines and improve picture quality significantly.
By identifying the specific type of screen issue your Sony TV is experiencing, and following these initial troubleshooting steps, you can determine whether a simple fix is possible or if further action is required.

Horizontal Line Causes
Internal Hardware Defect
Horizontal lines on a TV screen can often be traced back to internal hardware defects. One common culprit is failed gate drivers on the panel. These gate drivers are integral to the LCD panel and are not easily replaced. Ribbon cables connecting the driver board to the LCD panel could also induce horizontal lines. Applying pressure to the ribbon cable at the location of the line may help to diagnose the issue. If the line changes or disappears with pressure, it could indicate a failed bond. Conversely, an unchanged line might suggest a failed gate driver for that region, pointing to a panel issue rather than a board failure.
Panel vs. Board Issue
Diagnosing whether a horizontal line issue is due to a panel defect or a board problem is crucial. On a Sony Bravia TV, the symptoms could suggest either a tcon (timing control) or main/control board issue, or a more grave panel defect inside the screen itself.
| Issue | Possible Cause |
|---|---|
| Line changes/disappears with pressure | Likely failed bond |
| Line remains unchanged with pressure | Possible gate driver failure |
| Multiple lines across the screen | Could indicate a tcon board issue |
| Isolated line | Likely a localized panel defect |

DIY Troubleshooting
Reseating Connectors
Unplugging and reseating connectors and cables on the TV, such as the ribbon cables, could resolve horizontal lines issues. This simple troubleshooting step may help in cases where the screen exhibits jumping or flickering lines. Loose cables inside the flatscreen TV or dust accumulation interfering with the picture can be potential causes of these issues (iFixit – Brian Koleszar).
Steps to Reseat the Connectors:
- Unplug the TV from the wall.
- Carefully remove the back panel of the TV.
- Locate the ribbon cables and other connectors.
- Unplug and re-plug each connector to ensure a secure fit.

Checking Ribbon Cables
Horizontal lines on a TV screen are often caused by failed gate drivers on the panel. These drivers are part of the panel and cannot be easily replaced, requiring special equipment. If issues persist, it is recommended to check the flat ribbon cables that connect from the driver board to the LCD panel. Applying pressure to the ribbon cable corresponding to the location of the line might reveal a failed bond or a faulty gate driver for that region, which indicates a panel issue rather than a board failure.
Steps to Check Ribbon Cables:
- Unplug the TV from the power source.
- Remove the back panel carefully.
- Identify the flat ribbon cables connected to the driver board.
- Apply gentle pressure on the ribbon cable near the site of the horizontal line.
- Observe any changes on the screen.

Applying Pressure
Horizontal black lines, particularly in the middle of the screen, may sometimes self-correct after a severe power fluctuation caused by a power company failure. Applying gentle pressure to specific areas of the screen might also provide a temporary fix.
Steps for Applying Pressure:
- Turn off and unplug the TV.
- Lay the TV on a flat surface.
- Identify the general area where the horizontal lines appear.
- Apply gentle, but firm, pressure to the specific region.
- Turn the TV back on to see if the lines have disappeared.

Professional Solutions
When DIY troubleshooting steps fail to resolve horizontal lines on a Sony TV screen, professional assistance may be required. Here, we’ll discuss potential repair costs and considerations for replacing the television.
Repair Costs
Repairing horizontal lines on a Sony TV can be expensive, particularly if the issue stems from an internal hardware problem. According to JustAnswer, the cost for diagnosing and repairing a board issue, which typically includes parts and labor, is around $300. However, it’s important to note that if the problem is identified as a panel defect rather than a board issue, the TV might be irreparable, requiring complete replacement.
| Repair Type | Estimated Cost |
|---|---|
| Board Issue | $300 |
| Panel Defect | Not Repairable |

Replacement Consideration
In some cases, replacing the TV may be more cost-effective than repairing it—particularly for older models or when faced with significant hardware issues. Purchasing a new television can offer not only a resolution to the problem but also improvements such as enhanced picture quality, newer features, and a fresh warranty.
According to data from JustAnswer, a new 4K LED TV with contemporary features and a warranty can be bought for approximately $500. Given that the repair costs for significant issues can approach or exceed this amount, replacement becomes a viable alternative.
| Option | Estimated Cost |
|---|---|
| TV Repair (Board Issue) | $300 |
| New 4K LED TV | $500 |

Prevention and Maintenance
To prevent horizontal lines on your Sony TV and ensure its longevity, proper positioning and regular maintenance are crucial.
Positioning and Handling
Proper placement and care can significantly reduce the chances of encountering screen issues such as horizontal lines.
- Stable Placement: Place the TV on a stable, flat surface to prevent it from falling, which could damage internal components.
- Ventilation: Ensure the TV has adequate ventilation. Overheating can cause internal issues, leading to display problems.
- Avoid Direct Sunlight: Position the TV away from direct sunlight to prevent damage to the screen and internal circuitry.
- Avoid High Humidity: Place the TV in a room with low humidity to prevent moisture from affecting internal components.
- Careful Handling: When moving the TV, always support the screen. Avoid putting pressure on the screen to prevent damage to the panel and connectors.
Routine TV Care
Regular maintenance can keep your Sony TV in excellent condition and prevent issues like horizontal lines.
- Dusting: Regularly dust your TV, especially the vents and back panel, to prevent dust accumulation that can cause overheating or interfere with connections.
- Cable Check: Periodically check and ensure all cables are securely connected. Loose cables can lead to display issues (iFixit).
- Power Surges: Use a surge protector to protect your TV from voltage fluctuations that can harm the internal components.
- Clean Screen: Clean the screen with a microfiber cloth and a solution designed for screens to avoid scratches and build-up of residue.
- Firmware Updates: Regularly update the TV’s firmware to the latest version. Manufacturers often release updates to fix bugs and improve performance (Sony Support).
