TV Power Board Replacement Parts

TV power supply boards are critical components inside televisions that manage and distribute electrical power to various internal circuits. They convert the AC (alternating current) electricity from your home outlet into the lower-voltage DC (direct current) power required by the TV’s internal components like the main board, backlight, audio system, and screen.

A typical power supply board includes components such as transformers, capacitors, rectifiers, and voltage regulators. These parts work together to stabilize voltage and prevent surges that could damage sensitive electronics. Some power boards also include protection circuits that shut down the TV if a fault is detected, helping prevent fire or further component damage.

Signs of a failing power supply board include the TV not turning on, flickering, sudden shutdowns, or no power light. You may also hear a faint clicking sound when trying to power on. Common causes of failure include power surges, aging capacitors, or overheating. While some minor issues (like bulging capacitors) can be repaired, severe damage may require a full board replacement.
