Small PDF schematic in a RAR archive for an LS-9412P LED board, revision R10. LS-prefixed numbers are typically Compal daughterboards, such as power button or indicator boards, paired with a main LA board. The diagram helps trace LED driver signals, connector pinouts and the link back to the motherboard when indicators or buttons fail. At only 70.8 KB it covers the small board alone. Check that the LS number on the daughterboard matches before relying on it.
