Koryo TV Power Supply Boards – Original SMPS & PSU Boards
The Power Supply Board, also known as SMPS Board or PSU Board, is one of the most important electronic boards inside an Koryo television. It converts incoming AC electricity into multiple regulated DC voltages required by different TV circuits.
Without a functioning power supply board, the television cannot operate correctly. Even if the motherboard, display panel and other components are working, a faulty power board can prevent startup or cause unstable operation.
