LED TV Half Display Problem — Causes, Diagnosis & Repair Guide
LED TV Half Display Problem
Is your LED TV showing only half screen, vertical lines, partial display or split picture? Learn the common causes and which spare part may need replacement.
Half display problems are one of the most common LED TV display issues. Sometimes only one side of the screen works, while the other side becomes white, black, flickering or shows vertical lines.
In many cases, the issue can be repaired after proper diagnosis. At Great Bharat Electronics, we help customers identify and buy tested T-Con boards, motherboards, LVDS cables and other LED TV spare parts.

Common Symptoms of Half Display Problem
- TV showing only half picture
- One side black and one side normal
- Vertical or horizontal lines
- Split screen issue
- White display on one side
- Screen flickering partially
- Picture distorted or stretched
- One half darker than other
Main Causes of LED TV Half Display Problem
1. T-Con Board Failure
The T-Con board controls image processing between the motherboard and display panel. If the T-Con becomes faulty, the TV may show half display, lines, flickering or distorted image.
2. Loose or Damaged LVDS Cable
Loose LVDS cable connection between motherboard and T-Con board can interrupt display signal and cause split screen or partial display problems.
3. Panel COF Damage
COF (Chip On Film) damage inside the display panel can cause permanent half display issues. This usually happens due to heat, pressure or panel aging.
4. Motherboard Signal Issue
A faulty motherboard may send incorrect display signal to the T-Con board and create half screen, color distortion or flickering problems.
5. Panel Failure
In some cases, the display panel itself becomes defective. Panel-related faults are usually expensive compared to board replacement.
Which Part May Need Replacement?
| TV Symptom | Possible Faulty Part |
|---|---|
| Half screen display | T-Con Board / Panel |
| Vertical lines | T-Con Board / COF / Panel |
| One side white screen | LVDS Cable / T-Con |
| Split image problem | Motherboard / T-Con |
| Partial flickering | T-Con / Panel Section |
✅ Quick Checks You Can Try
- Restart the TV completely
- Check if problem appears on menu screen also
- Reconnect LVDS cable carefully
- Check for physical panel pressure damage
- Observe if lines change after warming up
- Compare HDMI input and TV menu display
⚠️ Important Diagnosis Tip
Do not order parts only based on TV model number. The same model may use different T-Con boards and panel versions. Always match board number and original part image before ordering.
How to Order the Correct Spare Part
