The page column refers to the schematics called "LA-8671P" by Compal from 2012-10-04, Rev. 1A_1004A. PTC are resettable fuses (deutsche Seite), it should never be necessary to replace them (in theory). The part numbers of the 2A fuses have typos in the schematics, but they are marked with "N" on the board (1A fuses carry the mark "H").
