Schematic in PDF form for an LG LED TV power supply board with part number EAX64905301. It shows the standby and main converter stages, the PFC section, feedback loops and output rails that feed the TV mainboard and backlight. Technicians use it to trace a dead or cycling supply, identify fuses, MOSFETs, optocouplers and controller ICs, and confirm expected output voltages. Any PDF viewer opens it. Compare the EAX code printed on your PSU board before relying on component values, since LG reuses similar layouts across many models.
