Introduction

A modern smart TV is built to deliver sharp visuals and an immersive viewing experience. However, when your OnePlus TV begins flickering, showing horizontal lines, or displaying unstable images, it can quickly disrupt your entertainment. Screen disturbances often indicate deeper hardware or software issues that need immediate attention. In such cases, visiting a OnePlus TV Service Center is the most reliable solution for diagnosing and fixing the problem.

Users across regions like Thane, Mumbai, and other major cities get easy access to experienced technicians and specialized repair hubs. Even third-party professional brands such as Dial Service Centre offer expert-level assistance for display and motherboard faults, ensuring long-term reliability and genuine replacements.

Common Causes of Screen Flickering or Horizontal Lines in OnePlus TVs

Understanding what triggers the issue helps you take the right steps toward repair.

1. Loose or Damaged Display Cables

One of the most common causes of flickering or horizontal lines is a loose LVDS (Low-Voltage Differential Signaling) cable, which connects the screen panel to the motherboard.

Symptoms:

• Random screen flickering

• Horizontal or faded lines

• Distorted colors

• Screen going dark temporarily

Why It Happens:

• Physical shocks

• Manufacturing wear

• Cable oxidation

• Frequent overheating

Solution:

Technicians typically reseat or replace the LVDS cable. Repair centers in Thane and Mumbai handle these repairs using advanced tools for safe disassembly.

2. Backlight Failure

The backlight provides brightness to your TV screen. If it fails, flickering or partial dimming may occur.

Signs of Backlight Problems:

• Screen flickers when brightness changes

• Dark spots or inconsistent lighting

• Screen looks fine on high brightness but flickers on low

Common Causes:

• LED strip failure

• Power fluctuations

• Overuse of high brightness

• Aging components

Fix:

A technician may replace the LED strips or the backlight inverter board. This repair is precise and best handled by professionals.

3. Software or Firmware Bugs

Software defects can cause screen instability, especially after system updates.

Possible Symptoms:

• Flickering during app usage

• Lines appearing only during streaming

• Screen freezing then flickering

Quick Fixes:

• Update the TV to the latest firmware

• Restart and clear cache

• Reset picture settings

• Perform a factory reset

If the issue continues, the firmware may need reinstallation at a service center.

4. Panel (Display) Damage

One of the most serious causes is physical damage or internal panel failure.

Symptoms:

• Permanent horizontal or vertical lines

• Multi-colored lines across the screen

• Flickering at specific areas

• Blurry or distorted picture

Why Panels Fail:

• Physical impact

• Liquid entry

• Manufacturing defects

• Overheating behind the panel

Solution:

Depending on severity, the technician may repair the T-CON board or replace the entire panel. Major repair hubs in Mumbai often stock compatible panel replacements.

5. T-CON Board Failure

The T-CON (Timing Controller) board controls the timing signals that generate smooth images on the screen.

When It Fails, You May See:

• White or grey horizontal lines

• Screen flicker when switching apps

• Ghosting or double images

• Display freezing

Causes:

• Short circuits

• Dust accumulation

• Voltage fluctuations

Fix:

A T-CON repair or replacement is done by technicians using micro-soldering tools.

6. GPU or Motherboard Issues

Severe flickering could indicate damage to the motherboard or the graphics module.

Symptoms:

• Screen flickers after long usage

• Image tearing

• Lines appearing even in boot screen

• TV randomly shutting down

Common Reasons:

• Overheating

• Damaged capacitors

• Power surges

• Faulty GPU pathways

Solution:

Motherboard repair requires expert-level diagnostics. Brands like Dial Service Centre offer PCB-level repairs with high-precision equipment.

7. Incorrect Picture or Refresh Rate Settings

Sometimes the issue is simply due to misconfigured settings.

Check These Options:

• Adaptive brightness

• Motion smoothing

• Refresh rate

• Picture mode

• HDMI dynamic range

Quick Fix:

Reset your picture settings to default. Incorrect modes can cause flickering in dark scenes or high-contrast movements.
