Short 34.2 KB PDF for the 2SD2261, an NPN bipolar transistor from the 2SD family, catalogued as a schematic though the content should be a brief datasheet. Expect the essential limits, electrical characteristics and pin identification needed to test the part and choose a replacement. Measure the original out of circuit to confirm a short or open junction, and pick a substitute whose voltage, current and power ratings are at least as high, matching the package to the board footprint.
