INTRODUCTION

A sudden purple or blue tint appearing on your TV screen can interrupt your viewing experience and indicate internal hardware or software issues. If you are facing this problem, the Sony TV Service Center is fully equipped to diagnose and repair the underlying cause. Sony televisions use advanced display technology, and any unexpected change in screen color often requires certified technicians for accurate resolution. This blog explains why this issue occurs, how the service center handles it, and why choosing authorized repair support ensures long-term reliability.

Why Does a Sony TV Screen Turn Purple or Blue?

Unexpected purple or blue discoloration generally occurs due to internal faults such as:

1. LED Backlight Failure

If the backlight produces uneven illumination or some LED strips weaken, the colors may drift toward purple or blue.

2. T-CON Board Malfunction

The T-CON board controls color accuracy and pixel data. When it develops signal errors, severe tinting may appear.

3. Loose LVDS Cable

A loose or damaged cable between the display panel and motherboard disrupts color processing.

4. Software Glitches

Firmware problems may cause color shifts during boot or while streaming.

5. Panel Damage

Physical stress or aging can distort display colors permanently.

The Sony TV Service Center uses diagnostic tools to identify which of these causes is responsible and provides repair or replacement accordingly.

How the Sony TV Service Center Fixes Purple or Blue Screen Issues

Authorized Sony technicians follow a systematic repair process to restore display accuracy.

1. Complete Visual and Hardware Analysis

Technicians begin with a panel inspection, checking for backlight irregularities, discolored zones, and imaging faults. They examine the T-CON board, LVDS cables, power supply stability, and backlight levels.

2. Repair or Replacement of Faulty Backlight LEDs

If uneven lighting is detected, the service center replaces damaged LED strips with high-quality, brand-compatible units. Proper backlight calibration is also performed to prevent future color tinting.

3. T-CON Board Repair

A faulty T-CON board is one of the most common reasons behind a bluish or purplish display. Depending on the condition, the board is repaired at the component level or replaced.

4. LVDS Cable and Connector Correction

Loose connectors are re-seated, and damaged cables are replaced. This restores correct color transmission between internal components.

5. Firmware Reset or Update

If software corruption is causing color distortion, technicians install the recommended firmware for your Sony model. This eliminates color glitches in streaming apps, HDMI inputs, or live channels.

6. Final Quality Testing

After repairs, the TV undergoes color uniformity testing, grayscale assessment, and pixel-level inspection. The goal is to ensure that the purple or blue tint does not reappear under any brightness or contrast setting.

How to Prevent Purple or Blue Screen Tinting on Sony TVs
