Vertical or horizontal screen lines on a TV are frustrating and often indicate deeper internal problems.

If you are wondering whether the Mi TV Service Center in Navi Mumbai can fix these issues, the answer is yes. Authorized Mi service professionals specialize in diagnosing and repairing display panel faults, T-Con board issues, and internal cable defects that cause screen lines.

Understanding Vertical and Horizontal Screen Lines in Mi TVs
Screen lines can appear for several reasons, and the type of line often indicates the underlying issue. Here’s an overview:
1. Vertical Lines
These lines run from top to bottom and can be caused by:
- Faulty T-Con board
- Loose LVDS cables
- Panel driver IC malfunction
- Damage to the display panel
- Software glitches causing refresh errors
2. Horizontal Lines
These run left to right across the screen and may be due to:
- Damaged display drivers
- Faulty panel backlight circuit
- Weak display ribbon connections
- Overheating of internal components
Both issues require professional diagnosis because attempting to repair these problems at home may cause further damage.
Common Causes of Screen Line Problems in Mi TVs
Understanding the root cause helps determine the appropriate repair:
1. Physical Damage
Even small pressure or accidental impact can damage the internal display layers, resulting in permanent lines.
2. Moisture or Humidity Exposure
Moisture entering the panel can damage the ICs and cause lines on the screen.
3. Faulty T-Con Board
The Timing Control (T-Con) board is responsible for image processing. When it malfunctions, distorted lines appear.
4. Loose Ribbon Cables
Improperly seated cables disrupt the image signal, causing intermittent or permanent lines.
5. Panel Aging
Over time, display panels may develop dead pixels, line defects, or uneven pixel response.
6. Software or Firmware Errors
Sometimes, outdated or corrupted firmware causes temporary lines until updated.
An authorized Mi TV Service Center in Navi Mumbai ensures accurate diagnosis and safe repairs using genuine parts.
How the Mi TV Service Center in Navi Mumbai Diagnoses Screen Line Issues
Authorized Mi technicians follow a structured, multi-step diagnosis process:
1: Power and Input Check
They first inspect the power supply, HDMI inputs, and external device connections to rule out signal problems.
2: Display Test
Technicians run color patterns and pixel tests to identify line frequency, thickness, and behavior.
3: T-Con Board Diagnostics
They inspect circuits, voltages, and IC functioning to see if the line problem originates here.
4: Ribbon Cable Inspection
Loose, damaged, or burnt cables are carefully checked.
5: Internal Panel Examination
If needed, the panel is opened to check display layers and electrical pathways.
6: Firmware Review
Experts check for software problems and correct them through updates or system reset.
This systematic approach ensures the exact problem is identified before repair.
Repair Solutions Provided by the Mi TV Service Center
Depending on the diagnosis, several repair options are available:
1. T-Con Board Replacement
If the T-Con board is defective, replacing it eliminates display distortion and line issues.
2. Ribbon Cable Reseating or Replacement
Loose or damaged cables are replaced with original Mi components.
3. Panel Repair (Driver IC Recovery)
Technicians carefully repair IC-level faults where possible.
4. Full Panel Replacement
In cases of irreversible panel damage, the service center recommends a complete panel change.
