When Might a Power Supply Board Need Replacement?

A failed power supply or LED driver board can be associated with several TV symptoms, including:

• TV will not power on
• No standby light or intermittent standby operation
• TV repeatedly powers on and off
• Backlight does not turn on
• Picture flashes briefly and then becomes dark
• Power-related operation becomes intermittent

These symptoms can also be caused by other TV components. Diagnose the television before replacing parts.

Installation Notes

Power supply board replacement generally requires removing the rear TV cover, disconnecting the wiring harnesses from the original board, removing the mounting screws, and installing the replacement board in the same position.

• Disconnect the TV from AC power before opening the cabinet.
• Photograph cable and connector positions before removing the original board.
• Handle the board by its edges whenever possible.
• Confirm every connector is fully seated before reassembling the television.
• Installation should be performed by someone familiar with electronic repair.

Electrical Safety

TV power supply boards contain high-voltage circuitry and capacitors that may retain electrical charge after the television has been unplugged. Do not work on the board while the TV is connected to AC power. If you are not experienced with electronic repair, professional installation is recommended.
