Harmony 1100
LCD Installation
1. Open the battery cover and remove the three visible screws.
2. Open the USB port cap cover. If you look carefully, you will see a very small screw. Remove this as well.
3. Push the USB rubber cover down so it is not helping to hold the case together. Holding the remote so that
the charging cradle contacts are facing up, insert a pry-tool right into the clamshell seam that is above
the area where the two screws were removed from the battery compartment. This is where the casing is
already loose since the screws were removed and you can easily insert the tool in this area. Slide the pry
tool toward the charging contacts, so that the clamshell locking tabs pop in that area. There should be two
locking tabs that release. Then, flip the casing over so that the top of the remote is facing up and then,
starting at the battery compartment, insert the tool in the corner and slide across the top side of the remote.
This will release the top locking tabs. Finally, the most stubborn tab is down the side where the USB port
is. To release this tab, insert the tool at the top of the Learning Port Lens (the smaller lens on the charging
terminal side) and slowly, but firmly, round the corner and come down a couple of inches. This should pop
the tab on this side. Try to avoid using a screwdriver, knife or other tool, which will leave pry-marks and mar
the casing seam.
4. As the case separates, the 2 plastic emitter lenses may pop off as well. This is not a problem and, in fact,
may make the next steps a little easier.
5. Fold the case open away from the 2 charging contacts - the faceplate and the screen will fold away from
the logic board and back case and you can see everything laying open held together by the wide ribbon
cable.
6. If you have a newer version of the 1100, you will see a plastic black plate that covers the entire back of the
LCD module. This is used to fill the space around the LCD, since it is slightly smaller than the first genera-
tion module and Logitech did not want to retool the entire front cover. To remove the LCD module from the
front cover, you can simply press it gently from the front. You may need to push or gently pry some of the
plastic mounting clips if the module is in very snugly. This is especially true if you have a first generation
LCD (which does not have the black plastic plate). Gently twisting the front cover can also help pop the
module free.
7. Now the screen lays flat away from the logic board, and your faceplate can be set aside so you don’t dam-
age it. There are three screws holding the logic board in place, one right by the hard number pad, the other
two on the opposite side just below the USB port. You can remove these and set them aside.
8. The hard button PCB should be removed to avoid damage when the logic board is removed from the back
cover. Open the ribbon cable clamp by carefully and gently sliding upward. Do not try to remove the
clamp. It should just move slightly up until it hits the stops, Then, very carefully, lift the hard button PCB
and slide the ribbon cable out of the receptacle. This is critically important – do not bend the ribbon
cable in any way! The solder joints that connect the cable to the board are very delicate and can eas-
ily develop a micro-tear. If this happens, some or all of your hard buttons will no longer work. If the PCB
will not easily lift from the casing, then you have a version that is being held onto the casing with a strip of
double-stick tape. If you encounter this, then slide a very thin, flat tool, playing card, etc, so that the PCB
can be lifted without too much strain. Be careful!
