When you open the LA-E791P Rev 2.0 schematic, you will be greeted with dozens of pages. Focus on these five critical sections:
: A common failure point where the motherboard receives power but fails to provide the critical core voltage to the processor, often leading to a "No Display" symptom. Charging Circuitry
Look for the dual MOSFETs or the PWM Controller chip (often a RT series chip like RT8223 or similar).
