LG L30W26 - LG L30W36 - LG MW30LZ10 - LG MW30LZ12 - LCD DIRECT VIEW TVs - DISASSEMBLE PROCEDURE


DISASSEMBLY
This model contains many screws. During each level of disassembly, keep the screws separated to ease reassembly. If desired, mark the screws and screw hole with different colored markers while disassembling.
  • Remove the cover and the stand.
  • Remove the back cover.
With the back cover removed, individual circuit boards can be removed. The ballast assemblies can be accessed by removing the shield covering them. To gain access to the lamps, continue with the disassembly, starting with the support assembly. To remove the support assembly, first remove circuit boards that block the assembly's screws.
  • To aid with reassembly, mark each screw and location with a marker to insure they are used in the correct location. Use a different color marker for each level of disassembly.
  • Remove the Speaker and Control panel circuit boards.
  • Remove the Jackpack circuit board.
  • Remove the screws from the NTSC board and lay it over on the Power Supply board (there is no need to disconnect the board). Now, remove the frame and front of the cabinet.
  • Remove the shields from the three remaining circuit boards.
  • Now remove the LCD driver board by removing the cables. There is a latch on each of the female connectors that must be lifted before the cable can be removed.
  • To gain access to the lamps, turn the panel over, remove the screen’s metal frame, and remove the screws holding the plastic frame in place.
  • Once the screws are removed, place the metal frame back onto the screen (do not replace the screws). Turn the assembly over and remove the LCD driver cables from their holders. Then carefully lift the back-light assembly up from the screen.
  • Replace any defective lamps by unplugging the connectors at both ends, release the bulbs from the plastic holders (in the middle of each lamp assembly), and lift them up.
LARGE SCREEN MODELS
The example was made using the 32LX1D. It is very similar to the 26LX1D, 26LX2D, 32LP1D, and 32LX2D.
1) Remove the stand and back cover.
2) Remove the Jack pack trim piece and shield.
3) Remove the main shield.
Now most parts can be accessed.
