Samsung SM-A20S schematic section dedicated to the LCD backlight, 4.62 MB PDF. It covers the backlight driver circuit, its boost coil, diode and capacitors, and the lines to the display connector that power the panel illumination. This is the page to consult when the screen shows a faint image with no light, when the backlight driver area heats up, or when a coil or filter must be identified for replacement. Readable in any PDF viewer; verify component positions on the actual board first.
