DISASSEMBLY
DISASSEMBLY
CABINET DISASSEMBLY
To gain access to the circuit boards and the Optics Engine, the cabinet must be disassembled (This process requires two
people). Use caution when removing and installing screws, use a low torque setting on powered screwdrivers. When
removing the lower back cabinet piece, be careful not to break a switch that is located in the middle. This switch
prevents the TV from operating when the back cover is off, it must be closed or the TV will not turn on.
The main PCB can be removed without disassembling the cabinet. Remove the back cover and the two screws below the
jackpack. Then, the Main PCB assembly can be pulled out.
1. Remove the bottom decorative piece by prying one
end out slightly using a paint scraper or large screw
driver (Care should be taken not to damage any of the
decorative pieces). Then grip and pull forward (A
substantial amount for force is needed to remove this
piece).
2. Now remove the upper decorative piece in a similar
fashion. Carefully loosen one end and pull this piece
forward. Do not bend this piece excessively. Note: the
double-sided tape across the top must remain intact.
3. Remove the lower back piece which is held on by
screws. Be careful not to break a switch that is lo-
cated in the middle. This switch prevents the TV from
operation when the back cover is off, it must be closed
or the TV will not turn on.
4. Now remove the screen assembly. It is held on with
screws on the front at the bottom and along the back.
5. Once the screws are removed, carefully pull the screen
a short distance away from the cabinet.
6. Remove the speaker and connections.
7. Now the screen can be removed.
