Named for the 2SC4003, this 79.4 KB PDF is listed as a schematic but appears to be a transistor datasheet. The 2SC prefix in JIS numbering indicates an NPN bipolar transistor. No package, brand or other detail is given in the name. Read it for the pin configuration, voltage and current limits, and power rating, which are what you need to diagnose a shorted device and choose a replacement. Any PDF reader opens it. Check the code printed on the component matches before relying on these figures.
