VGH stands for Vertical Gate High.
It is a voltage used in liquid crystal displays (LCDs) to control the horizontal position of the liquid crystal molecules.
VGH positive 24V to 29V as per panel size
The exact voltage needed for VGH depends on the specific LCD display technology and manufacturer
VGL is the abbreviation for Gate-to-Source Voltage Low, Negative Voltage
which refers to the voltage applied to the gate terminal of a field-effect transistor (FET) to control the flow of current between the source and drain terminals.
It is commonly used in the context of FET amplifier circuits and is typically specified as a range of values, such as -5v to -11v

LCD and LED TV panels are delicate components that can develop various issues over time. Understanding how to diagnose and repair these panels can save costs and extend the TV’s lifespan. In this guide, we’ll cover common panel problems, repair techniques, and essential tools needed for professional LCD/LED TV panel repair.
Before repairing, it’s crucial to understand how an LCD/LED panel works. The main components include:
✅ TFT (Thin Film Transistor) Panel – Controls the pixels.
✅ LED Backlight – Provides brightness and illumination.
✅ COF (Chip on Film) – Manages image processing.
✅ T-Con (Timing Controller) Board – Controls panel signals.
✅ Power Supply Board – Regulates power flow.
Symptoms: TV powers on, but the screen is blank.
Possible Causes:
Fixes:
✅ Use a flashlight to check if the display is working but the backlight is off.
✅ If the backlight is faulty, replace LED strips.
✅ Test the T-Con board and ribbon cables for faults.
Symptoms: Thin or thick lines appearing on the display.
Possible Causes:
Fixes:
✅ Re-seat and clean the COF ribbon cables.
✅ Check the T-Con board and LVDS cables.
✅ If lines persist, the panel may need replacement.
Symptoms: TV screen brightness is low or flickers.
Possible Causes:
Fixes:
✅ Open the panel and test LED strips using an LED tester.
✅ Replace weak LED strips or power supply components.
To repair screen panels, you need professional tools:
🔹 Multimeter – For voltage testing
🔹 LED Tester – To check backlight strips
🔹 COF Bonding Machine – To fix loose COF ribbons
🔹 SMD Rework Station – For chip-level repairs
🔹 T-Con Board Tester – To diagnose display faults
✅ Keep the TV in a cool, dust-free environment.
✅ Avoid pressing or touching the panel too hard.
✅ Use a surge protector to prevent voltage fluctuations.
✅ Clean the screen with a soft microfiber cloth (no harsh chemicals).
LCD/LED TV panel repairs require technical knowledge and the right tools. By diagnosing issues correctly, technicians can save time and money while providing quality repairs.
