Pre-release revision R0.3 schematic for Compal board LA-4971P, in a RAR archive of about 1.18 MB. An R1.0 version of the same board exists too, so compare the revision silkscreened on your PCB and pick the matching document, since early issues can differ in parts and nets. The name lists no brand or model, only Compal's LA code. With the extracted PDF, a technician can trace power rails, check signals between chips and locate test points while diagnosing faults.
