    • Carefully lay the TV screen down on a clean flat table with the back side facing you.

    • Using a #3 Phillips head screwdriver, remove the screws holding the back cover on.

    • Thoroughly clean the cover and boards using a damp towel (I like to use 91% isopropyl alcohol) and if heavily soiled use a vacuum with a brush.

    • Using the #3 Phillips head screwdriver, remove the screws holding the power supply board on.

    • Unplug the connectors connected to the board setting aside and carefully noting placement for later connection to the new board.

    • Insert the new power supply board into the location where the old board was located.

    • Follow the previous steps to connect the cables and screw in the screws.
