2.0 Schematic ((link)): Zso50 La-a992p Rev

Some sellers offer USB drives containing thousands of Compal schematics, including this one, for ~$10.

Pay close attention to components marked "DO NOT POPULATE" (DNP). On Rev 2.0, some resistors from Rev 1.0 are removed to alter timing sequences. If you follow a Rev 1.0 guide and add a missing resistor, you may cause a short. zso50 la-a992p rev 2.0 schematic

Open the schematic and search for " PLT_RST " (Platform Reset). Step 2: Locate the test point (TP) for this signal. On page 8 of the LA-A992P Rev 2.0, it connects to the PCH. Step 3: Probe with an oscilloscope. If PLT_RST is pulsing, the CPU is trying to boot. If it's stuck low (0V), the PCH isn't happy. Step 4: Trace back what PLT_RST depends on. The schematic shows it requires: - SYS_PWROK (From the power sequencer). - All core voltages present (VCCSA, VCCIO, VCC_CORE). Step 5: Use the Boardview to physically locate the inductor for VCCSA (Usually PL802). Check voltage. If missing, go to page 5 of the schematic to find the VCCSA controller.
