Compact 29.9 KB PDF for the 2SC5775 transistor, filed under schematics despite the name being a bare part number. Following the Japanese naming convention, 2SC marks an NPN high-frequency bipolar transistor, so expect a short datasheet with ratings, electrical characteristics and a package drawing. That information supports in-circuit testing, identifying the collector, base and emitter leads and choosing a compatible substitute. Check the tiny SMD marking code on the board against the datasheet before swapping parts.
