Tips & Warnings

• On some Samsung TV's there will be a White wire that runs from the old deflection board to the front of the TV. If this is the case you will need to remove the front lower panel of your TV to replace that wire. To remove the front panel, first remove the screws at the very bottom of the panel. Then pull each side of the panel out toward you to release the clips that hold it in place. Do this GENTLY and do not pull the panel toward you once the panel releases from the clips. You need to pull the panel downwards to release the top clips. You will see the wire going up into the Red Green Blue panel at the front of the TV. Pull the wire downwards to release it. Feed the new wire from the board to the front on the TV and replace it in the same place as the old wire. Replace the front panel on the TV.
• Important: UNPLUG THE TV FROM THE WALL OUTLET BEFORE WORKING ON IT.
