LE645 and LE654 Main Board Replacement

When replacing the Main PWB, select the correct main board by confirming the 5th position of the Serial
number. The Serial number label is located on the back of the TV or on the side label.

Using the incorrect main board may cause the image to appear grainy or the image may appear upside
down.
