Apex IP46004-L07 TV Power supply Repair Service

Professional diagnostic and board-level repair service for this Apex IP46004-L07 TV Power supply.

The Apex IP46004‑L07 is the main power‑supply board used in the LD4088 series of Apex TVs, providing regulated 12 V and 5 V rails to the tuner, backlight inverter, and other subsystems. Common failure points on this board include electrolytic capacitor leakage or bulging (especially on the 33 µF/6.3 V caps near the input filter), burnt-out rectifier diodes in the primary side of the transformer, and overheating of the integrated voltage regulator due to inadequate heat sinking. First‑check diagnostics: verify that the AC mains input is present and within spec; measure output voltages at the board’s 12 V/5 V test points for proper regulation; visually inspect for bulging capacitors, burnt marks on ICs or diodes, and ensure the heatsink is clean and properly attached.
