Circuit diagram in PDF format for the TCL power supply board SHG5504B09-101H, about 788 KB, labelled with the Russian word for schematic. It covers a TV power module, useful for diagnosing no-power, clicking or standby faults by following the primary switching stage, feedback loop and secondary output rails. Component references and values help when replacing failed capacitors, MOSFETs or controller ICs. Work carefully, as the primary side holds mains voltage, and check the board code printed on the PSU matches before relying on it.
