Circuit diagrams in PDF form for the Lenovo D222B LCD monitor, compressed as RAR. Monitor repair usually involves the power board, LED backlight driver and scaler logic, and these sheets help trace each stage when the screen stays dark, flickers or shows no image. The B suffix marks a separate variant from the plain D222, so take care not to mix up the two documents. Check part numbers on the monitor's internal boards against the schematic before ordering parts.
