Schematic diagram set for the Compal LA-2821P main board at revision 1.0, archived as a RAR of about 1 MB. A separate R0.5 engineering copy of the same board also exists, so compare the revision printed on your PCB and choose the matching document. Technicians use these pages to trace power rails from the DC jack and charger through the regulators, identify fuses and MOSFETs, and work out where a short or missing voltage originates. Extract it first, then view the drawing in a PDF reader.
