Schematic for Compal mainboard LA-D841P in PDF form, packed as a 2.86 MB RAR; the name gives no brand or revision. Opened in a PDF reader, it lets a technician trace power rails, follow the power-on sequence, read part values and track signals when diagnosing no power, shorts or charging faults. Compal prints its LA-xxxxP code and revision on the PCB, so check that they match before trusting net names and values. Pairing it with the boardview for the same board makes locating components much faster.
