The GYD9E is almost always sold as part of the retrofit kit. You can purchase it from:
Features an ultra-compact length of 69 mm and a width of 19 mm .
Use a digital multimeter to trace the stable 12V or 24V supply rails, the ground plane, and the backlight activation signal pin on the main power board. gyd9e datasheet
Ensure the television or monitor is fully unplugged from alternating current (AC) mains before opening the enclosure.
The GYD9E is a constant current source LED driver. Below is a specification table compiled from component listings and confirmed by repair experts in technical forums.
A Chinese website article titled "gyd-9e恒流源电路原理" (gyd-9e Constant Current Source Circuit Principle) confirms that this is a standard buck constant‑current topology. The output current can be modified by changing the value of the current‑sense resistor(s) on the board, a useful feature for matching different LED strips. You can purchase it from: Features an ultra-compact
Hook up the positive and negative leads of your internal panel LED strip to the high-voltage output terminals.
A formal, manufacturer‑issued datasheet is often hard to find for generic products like the GYD‑9E, as it is a finished module, not a single IC. Here’s a practical guide to finding the specific information you need.
| Parameter | Value / Range | Details | | :--- | :--- | :--- | | | GYD-9E | Also referred to as GYD9E or GYD9E driver | | Input Voltage (V_in) | DC 10V - 30V | Wide operating range from sources like power supply units (PSUs) | | Output Voltage (V_out) | DC 7.5V - 9.5V | Dynamically matched to the forward voltage of connected LEDs | | Output Current (I_out) | 10 mA - 1000 mA | Adjustable to drive different LED loads | | Output Channels | 1 Channel | Common positive output for one or two LED strips wired in parallel | | Control Logic (ON/OFF) | High (3.3V - 5V) | Requires a positive DC voltage to enable output | | Dimming Control | Yes | Typically via a PWM (Pulse Width Modulation) or DC voltage signal | | Driver Dimensions | 70mm × 20mm | PCB (Printed Circuit Board) dimensions | | Typical Load | 2 × LED Strips | Designed for 15"-24" screens | The GYD9E is a constant current source LED driver
RDS(on)cap R sub cap D cap S open paren o n close paren end-sub ) or low quiescent currents to curb parasitic power drain.
: As of late 2025, many large‑scale Russian and Chinese distributors have listed this part as "discontinued" or "end of life" (EOL) due to industry shifts toward integrated LED boards on newer TVs. For long‑term projects, consider bulk‑buying the driver module separately while 4030‑type LED strips remain available.
The search for a "gyd9e datasheet" primarily leads to the practical world of display repair and modification. The is a versatile, user‑friendly LED driver board that has become a standard tool for replacing old CCFL backlights with modern LED technology. While an official, manufacturer‑issued datasheet may not exist, the collective knowledge found in repair forums and the information from component suppliers has effectively documented its core specifications and wiring.
