How to install
your new Harmony One
Front Cover/Touch Screen
Important! Before you begin working on your Harmony One, you must discharge any static electricity you
may be carrying around. Ideally, you should wear an anti-static wrist strap as you work. If you do not own
an anti-static device, at least touch a grounded appliance (the metal on the back of a computer tower works
well) before you begin working. The components inside the Harmony One are sensitive to static electricity so
it is very important to take these precautions!
Before you get started, familiarize yourself with the parts pictured below.

Disassembly Procedure
1. Remove the battery compartment cover. There are
four screws in this area that need to be removed. Two
are immediately visible on either side of the serial
number sticker. Remove them with a small Phillips
head screwdriver and set them aside. There are also
two hidden screws under the sticker (if there is no
sticker, all four screws are visible). To remove the
sticker, use an x-acto blade or razor to get under-
neath one of the corners and peel it up gently. Once
you get it started, you can use tweezers or small
pliers to peel it off. If you are careful, you can lift the
sticker and still be able to re-apply it later. Remove
the two screws and set them aside.
2. Now it is time to remove the black ‘rubberized’ back
plate. This looks like soft rubber but it is actually a
hard piece of plastic. Start at the top using a pry tool
and pry up the left corner. Then, move to the top
right corner and pry that up as well. Once the two
top corners are free, you can move the pry tool to the
middle and, like a lever, bury it deeply and pull gen-
tly forward, prying the back plate towards you. This
is not an exact science and you may need to experi-
ment and pry in a few different places. You may also
pry at the sides and use your hands to keep the piece
from locking itself back in its side groves. There is a
tab in the middle/center of the plate that will offer
some resistance so the plate may come free sudden-
ly. The only thing you need to really be aware of is
that, on some Harmony One’s, there is a sticky piece
of double-sided tape at the very bottom of the plate
(just below the raised dot). So, if the plate seems to
come free but appears stuck in this area, use your pry
tool to ‘peel’ the plate off of the tape, or simply use
your hand and pull from the side. Once the plate is
off, we can move to the next step.

3. Removing the plate will expose three screws; one
at the top left and two at the bottom on either side.
These screws are the same size as the ones you
already removed. So, use your Phillips head screw-
driver and place these screws with the others.
4. Now it is time to separate the two clamshell halves
of the Harmony One. A triangle pry tool is best for
this work and you should not use a screwdriver or
any other kind of sharp tool. If you do not have a pry
tool, then a hard guitar pick works well. Start with
the remote face-up in your hand and take the pry
tool and place it into seam of the clamshell casing at
the top right-hand corner. Then, simply slide down
the seam, with the pry-tool angled slightly. Do this
action quickly and rmly. Then, rotate the remote so
that the front of the remote is facing you. Insert the
pry-tool into the seam by the Off button and slide
down the seam as you did before. Note that you may
need to do this more than once in order to pop all of
the tabs. Once it appears that the front cover is free,
do not lift the front cover off! There is too much risk
of pulling the touch screen ribbon cable and detach-
ing the delicate leads from the inside surface of the
front cover. To help prevent this, turn the remote
upside-down and lift the back cover up and off of the
front cover. Do this gently and carefully! Watch for
the small plastic ‘window’ that covers the learning
port at the back of the remote. This can sometimes
fall out of the back cover slot. So, make sure you do
the disassembly in a place where you will be able to
nd this almost invisible piece should it fall!
When you are done, the back cover of the Harmony
One can be set aside and you are left with the front
cover touch screen and logic board.

5. Turn the remote so that the logic board is face up.
There are two screws that need to be removed so
that the front cover can be separated from the logic
board. They are near the bottom of the remote on
either side.
These screws are shorter than the screws you
removed previously so do not mix them up.
6. Now, the only other thing that needs to be done
before the logic board can be removed from the
front cover is to unclip the touch screen ribbon
cable. If present, gently remove the piece of clear
tape that is covering the connector. Flip the black
connecting clamp up and back. Do it gently and
carefully since it can sometimes detach from the
connector and be difcult to put back on. Slide the
ribbon cable out.
7. To remove the logic board, start by lifting it up
slowly and gently at the ‘soft’ connection at the
top left (a hole in the board with a mounting post
through it). Do this carefully and make sure that
the touch screen ribbon cable does not get tugged
or pulled. It may stick a little at the top, so you may
need to wiggle it free from the post, but then the
board can be ‘rolled’ to the right and removed, and
this is a little safer than lifting straight up, where
there is risk of pulling the touch screen ribbon
cable. This is the most common error that is made
during disassembly. If the digitizer connections on
the inside surface of the front cover detach even
slightly, the touch screen will not function properly
or may not work at all. There is no reliable repair
for this condition and the front cover will require
replacement if this happens. Now, depending on
how you removed the board, only the PCB itself
will come free, or you may have lifted off the plas-
tic button guide template and/or the rubber button
pads. Either way, all these components simply go
back together and sit on top of one another – no
screws, glue, etc. If the plastic button guide sticks
to the logic board when it comes out,or if it stays
on top of the button pad, either way is ne. Just
make sure that if you separate all the components
that the plastic guide is re-installed in the correct
way (see reassembly pictures).

Page 5
1. Take the button pads from the old face plate and
move them onto the new one. Just drop the two
pads right in and pat them down, making sure that
they are fully inserted. Also make sure that the on/
off button is oriented the correct way. There are two
tiny holding pins (part of the front cover) that are
actually inserted into the on/off button pad to help
hold it in. Turn the front cover face up to verify that
the button is in correctly. Now, if the white plastic
button guide is not attached to the logic board and
is just another part on the table, then place it on top
of the button pads.
Make sure that the guide hole with rectangular
sides is placed on the pad so it is at the top right as
shown in the picture.
2. Now drop the logic board back on top of the button
pad (or button guide if not attached to the board).
Make sure that the post at the top of the front cover
has been fully inserted into the hole in the logic
board. Push down gently on the board and reach
your hand around to the front and click the but-
tons so you can feel if the board and front cover are
aligned correctly.
3. Re-insert the ribbon cable into the connector. Push
it all the way in and close the connecting clamp
slowly and carefully. If you close the clamp quickly
or aggressively, it may come forward too far and ac-
tually detach from the connector. You can reinstall
the clamp, but it can be difcult to do. If this hap-
pens to you, pull the ribbon cable out before you
attempt to reseat the clamp.
4. With the ribbon cable installed, replace the two
shorter screws that you removed before. Make sure
they are the shorter screws! At this point it is a
good idea to turn the remote face up and simply
press the keys and test that they seem to be aligned
correctly and have the appropriate tactile response.
Reassembly Procedure

5. With the logic board face up, take the back cover
plate and align it with the board. You can verify
alignment by seeing that the screw hole at the top
left of the back cover is directly over the mount-
ing post at the top of the logic board. The next part
is a little tricky. What you want to do now is press
the front and back pieces back together. So, hold-
ing the remote with both hands press the front and
back pieces together starting at the top.
6. Once the top has been engaged (even if not com-
pletely), turn the remote face up and continue
pressing the front and back together – moving
down towards the middle and then the bottom.
You should hear and feel the locking tabs snapping
together and engaging. Once you are done, inspect
the edges very closely to see if a locking tab did
not engage.
There should be no gaps between the back cover
sides and the front cover and the surface of the
touch screen should be virtually ush with the
sides. If you see any part that is raised or there is
a gap at the sides, apply gentle but rm pressure
at that point until the front and back covers snap
together.
At this point, you can test the installation before
going any further. Insert the battery and allow the
remote time to boot-up. Test the touch screen. If
all is well, remove the battery and continue with
re-assembly.

7. Replace the three screws that rmly attach the
back cover to the logic board. Then, you are ready
to reinstall the ‘rubberized’ back piece. This piece
just snaps back in. Align the piece with the back of
the remote and press rmly at the top. Move to the
middle and press again. You should feel and hear
very denite engagement. Press rmly along the
sides and length of the piece to ensure that all tabs
have been engaged. Then, inspect the edges. If it
appears that a side tab did not fully engage, simply
press the spot sideways and it should click right in.
There should not be any spaces between this piece
and the body of the remote.
8. Install the remaining four screws back in the bat-
tery compartment and, if desired, re-apply the
serial number sticker. If it came off cleanly there is
generally enough glue to stick it back on.
Do a nal test to make sure everything works as expected. Feel free to contact me if you have any questions. I’m
always happy to help.
