Compal LA-B291P schematic at revision 1.0, in a 1.16 MB RAR archive. The LA-B291P code follows Compal's board numbering, where the letter after LA- belongs to the newer series of project codes and the trailing P marks a variant of the base design. Use the drawings to trace power rails, follow signals between chips and locate components when hunting a short or missing voltage. Because P and non-P boards can differ, read the full code and revision on the PCB silkscreen before relying on this schematic.
