Schematic for a Lenovo LCD monitor, model D222, supplied as PDF in a RAR archive. Monitor schematics usually cover the power supply board, backlight driver and scaler mainboard, making them useful for no-power, dim-screen or no-signal faults. Use the diagram to trace supply voltages, check fuses and MOSFETs and follow the backlight enable lines. Panel and board revisions can vary within one model, so compare the board markings with the drawings before replacing parts.
