DISASSEMBLY
Note: 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.
1) Remove the cover and the stand.
2) 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.
3) Remove the Speaker and Control panel circuit boards.
4) Remove the Jackpack circuit board.
5) 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.
6) Remove the shields from the three remaining circuit
boards.
7) 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.
8) 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.
9) 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
their holders. Then carefully lift
the back-light assembly up
from the screen.
10) Replace any defective
lamps by uplugging the
connectors at both ends,
release the bulbs from the
plastic holders (in the middle
of each lamp assembly), and
lift them up.
