Schematic for Compal board LA-K862P, revision R1A, archived as a RAR of around 3.8 MB holding the PDF. The circuit diagram covers power rails, sequencing and signal paths, helping a technician determine which regulator or enable line is at fault. Compal names its boards in the LA-xxxxP format; the brand is not given. Use it together with the matching R1A boardview, and confirm the revision printed on the PCB, as part numbers and circuits can differ between revisions.
