To remove the LCD-panel, carry out the following steps:
1. Disconnect the cables (1) from the "L" and the "R"
loudspeakers and remove the cables from their cable
clamps (1, see Figure "L" and "R" loudspeaker cables and
cable clamps").
2. Important: Unplug the LVDS connector (1) on the LCD
panel (see Figure "LVDS connector").
Be careful, as this is a very fragile connector!
3. Unplug the connectors (1) from the Side I/O panel and from
the LED panel and remove the cables from their cable
clamps (see Figures "Side I/O panel" and "LED panel" at
the beginning of this chapter).
4. Take the Keyboard Control panel out of its brackets and
remove the Keyboard Control cable from its cable clamp
(see Figure "Keyboard Control panel" at the beginning of
this chapter).
5. Remove the fixation screws from the LCD panel (see
Figure "LCD panel fixation screws"; the two types of torx
screws, 6 small ones and 4 large ones, are indicated by the
two screwdrivers).
6. Unplug the connector of the LCD panel flatcable, at the "R"
speaker side of the TV set, from connector 1316 on the
lower left side of the Class D audio amplifier/STBY power
supply panel (see Figure "Class D audio amplifier/STBY
power supply panel").
7. Lift the "L" speaker side of the metal frame 10 cm from the
LCD panel and hold it in this position. Now, loosen the LCD
flatcable and the "L" loudspeaker cable from their clamps,
and disconnect the LCD flatcable connector from the LCD
panel (see Figure "LCD panel connector").
8. Lift the metal frame (together with all PWBs) from the LCD
panel.
Take care not to damage the fragile LVDS cable.
9. After removal of the metal frame, you can lift the LCD panel
(1) from its plastic frame (see Figure "LCD panel").
10. If the plastic frame is damaged, replace it by a new frame,
after removing the loudspeakers, the Side I/O panel, the
Keyboard Control panel, and the LED panel.
