Compatible Screen Sizes 15" to 24" Widescreen panels Optimized for standard desktop/TV backlights. Control Signal Logic High Level: Low level ( ) disables operation. Physical Dimensions Ultra-slim form factor for tight chassis spacing. Pinout Configuration and Interface Layout
The GYD-9E is a universal or replacement constant-current power supply board designed to drive LED strips in 11" to 20" LCD monitors and televisions. It is frequently used in repair scenarios where the original internal backlight driver has failed. Key Specifications Application: LED Backlight Power Supply (Tira LED TV LCD) Supported Screen Sizes: 11 to 20 inches Input Voltage: Typically operates around +15V DC Major Components:
Expect an operating current roughly in the range of 3.5mA to 4mA depending on the active sensors. gyd-9e datasheet
When analyzing the datasheet, focus on these three critical areas:
