Schematic in PDF format for the AOC T2965M, a 4.46 MB document covering this AOC monitor and TV model. Diagrams like these let a technician trace power supply outputs, scaler and panel interface lines, backlight driver circuits, and the voltage regulators feeding the main board. They are useful for chasing shorts, checking missing supply voltages, and identifying component values when markings are burnt. Compare the board code printed on the PCB with the drawings, since manufacturers sometimes ship one model with different main boards.
