Compal LA-1121 schematic set at revision R1C, packed in a RAR archive of about 1.68 MB. LA- followed by digits is the Compal project numbering printed on the mainboard silkscreen, and this is an older, low-numbered board. Extract it with WinRAR or 7-Zip, then open the drawing in a PDF viewer to trace power rails, follow signal paths and identify components while checking a short or no-power fault. Confirm that the PCB really reads LA-1121 with revision R1C, because earlier revisions can differ in parts and routing.
