PDF reference for the 2SK2993 transistor, 424 KB. The file name carries only the part number, which under the JIS scheme denotes an N-channel field-effect transistor, so the content is most likely a manufacturer datasheet rather than a schematic. Use it to read off the package type, pin functions, breakdown voltage and drain current limits, then pick a replacement with equal or better ratings. Diode-mode measurement between pins helps confirm whether the original device is shorted.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @cyberlanelectonik. Enginerys does not host this file.
