LG LED TV POWER SUPPLY BOARD MODEL NUMBER OLED55C8PCA Digital Electronics Services pune maharashtra 9850791757 9763720390 (All India (COD) Cash on Delivery Service Available The Switch Mode Power Supply (SMPS) board for the LG OLED55C8PCA is part number EAY64749001 (associated with PCB model EAX67858001). It is commonly labeled as the LGP55C8-18OP board.Technical SpecificationsInput Voltage: AC 100~240V, 50-60Hz.Standby Power: Under 0.5W.Key Output Voltages:Standby (STBY): 3.5V must be present when AC is applied.Main Voltages: 12V and 24V are generated after the PWR_ON signal is received.Panel/T-CON Power: 12V and 24V for the T-CON and panel drive.Diagnostic & Testing ProceduresForced Power-On: To test the board independently of the main board, disconnect the main board cable and jump the PWR_ON pin to a 3.5V standby pin. This should trigger the relay click and activate all output voltages (12V/24V).Fault Indicators:If the red standby LED is not lit but standby voltage is present, the issue may be the Inrush Current Limiter (ICL).If the unit clicks on and then immediately off, it often indicates missing 12V output.Check for failed fuses, specifically Fuse F100.Service & SafetySafety Warning: The board contains large electrolytic capacitors that hold a dangerous charge even after the TV is unplugged. Wait several minutes before handling.Compatibility: This board is also used in other 55-inch C8 and B8 models, such as the OLED55C8PUA and OLED55B8PCA.Would you like the full pinout diagram or guidance on how to check specific component failures on this board?
