Description

This SMPS AC/DC power supply board replaces a failed internal power module to restore a TV's ability to power up and distribute low-voltage power to internal circuits. Improves reliability when the main board receives correct voltages. What it does

• Converts incoming AC mains to the DC voltages used by the TV's main and backlight circuits.
• Commonly repairs symptoms such as no power/power light off, TV not turning on, or intermittent shutdowns.
• Regulates and protects downstream components from voltage faults and surges.
• Works alongside the main board and control boards to ensure stable system power.

What's included

• One SMPS AC/DC power supply board (single complete board as shown)

Install notes

• Disconnect the appliance from power before starting; allow capacitors to discharge.
• Take photos of all connector positions before disconnecting; reconnect wires to matching keyed connectors only.
• Handle the board by the edges and avoid ESD-sensitive components; use an anti-static wrist strap if available.
• If issues persist after replacement, test incoming mains and main-board connections before returning the part.
