Display (LCD) circuit schematic for the Samsung SM-A23, a 2.78 MB PDF sheet. It documents the display connector pinout, the MIPI data lanes, panel supply voltages and control signals between the panel and the processor. A technician uses it for no image, lines on screen or a display that stays black while the phone runs, checking voltages at the connector and looking for shorted filters. Make sure the board variant matches before relying on part references, as regional SM-A23 versions may differ.
