HP- LT3200_ HP-LT3700_HP-LT4200_HP-LT4700 _ DISASSEMBLE PROCEDURE _ 1 of 2

                                       [1 of 2]
  • Carefully place the TV with the glass screen facing downward on a padded, stable table.
  • Position the bottom of the TV near the edge of the table so the pedestal hangs off the edge of the table.
  • Remove the four screws.
  • Carefully lift the pedestal off the TV.

DISASSEMBLING THE PEDESTAL
  • Position the pedestal so you can access the screws from the bottom of the pedestal.
  • Remove the four screws that hold the two pieces of the pedestal together.
  • Note: Hole usage varies depending on model.
  • Separate the two pieces of the pedestal.
REMOVING BACK COVER
  • Remove the thirteen screws as shown.
  • Note: Screws 9, 10, 11, 12, and 13 are sheet metal screws. During reassembly, make sure you return these sheet metal screws to their proper location.
  • Note: The 47-inch model has two extra screws (total of 15), one on each side toward the bottom of the unit.
  • On all sides of the unit, press the side of the back cover inward to release it from the inner latches.
  • Note: All models except for the 32-inch have small bumps on the edge of the bezel that indicate the locations where the cover is connected to the bezel. Apply pressure at these locations to loosen the cover.
  • Note: Removing the cover can be difficult and may take some time.
  • Carefully lift the back cover straight up off the unit.

REMOVING THE FUNCTION KEY BOARD
  • Lift the function keyboard from the slot and detach the cable from the connector.

INSTALLING THE PCA INTO THE KEY BOARD
The keyboard PCA may not come installed into the keyboard. If not installed, use the following procedure to install:
  • Make sure the connector on the PCA is facing outward so it fits into the slot in the keyboard, and make sure the buttons on the PCA are facing down and aligned with the buttons on the keyboard.
  • One side of the keyboard has two tabs. Snap the PCA into the slot below the two tabs.
  • While properly aligning the PCA so it is straight in the keyboard, press the PCA down into the slot below the tabs on the other sides of the keyboard until it snaps into place.
REMOVING THE INFRARED BOARD
  • Remove the one screw securing the infrared board.
  • Lift the infrared board and detach the cable from the connector.


On 32-inch models, to replace the IR board, plug the cable into the connector on the IR board before you replace the screws.
REMOVING THE WALL MOUNT BRACKET
  • Remove the four screws and lift the wall mount brackets away from the board cover.
