The first MOSFET (PQA1) is a frequent failure point. Technicians often find that 19V reaches the first MOSFET but does not pass through because the gate signal is missing or there is a short on the output side.
can be more elusive. Technicians often rely on a combination of the Rev 1.0 schematic and BoardView files la-e801p rev 2.0 schematic
Technicians often find 19V reaching the first MOSFET, but failing to pass through due to faults in components like (often identified as a dual transistor). The Missing Display: The first MOSFET (PQA1) is a frequent failure point
