Compact 99.3 KB PDF dedicated to the 2SA1732, a part number following the Japanese JIS scheme in which 2SA denotes a PNP bipolar transistor. The file name gives no board or equipment model, so treat it as a component datasheet rather than a circuit diagram despite its schematic classification. Use it to read the pinout and package drawing, check hFE class and voltage ratings, and test the transistor with a meter in diode mode, confirming the two junctions behave as expected for a PNP device before deciding it is faulty.
