Common TV Symptoms Fixed

A faulty power supply may cause the TV to fail to power on, lose standby power, or shut down unexpectedly. These symptoms can also have other causes; confirm the power supply is faulty before replacing it.

Fitment & Ordering Guidelines

Verify the white-sticker part number RUNTKB286WJQZ, PCB/board number APDP203A1, full TV model suffix, and any version code against your original board. No specific supported version code or substitute part is confirmed in this listing. Compare connectors and labels rather than choosing by appearance or screen size alone.

Disconnect the TV from power before service. Power-supply capacitors can retain hazardous charge after unplugging; installation by a qualified TV repair technician is recommended. Use ESD precautions when handling the board and avoid touching circuitry.
