Important! Before you begin working on your Harmony 900, 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 H900 are sen

Disassembly Procedure . 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

. 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. . Now, this is probably the trickiest part of the dis- assembly. It is time to separate the two clamshell halves of the 900. A larger bladed pry tool is best for this work. Start with the remote face-up in your hand

. Turn the remote so that the logic board is face up. There are three screws that need to be removed so that the front cover can be separated from the logic board. Two of the screws are near the bottom of the remote on either side and the third screw is almost dead-center just above the large silver-col- ored component cover. These screws are shorter than the screws you removed previously so do not mix them up. . Now, the only other thing that needs to be done before the

Reassembly Procedure . 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 transpar- ent p

. With the logic board face up, take the back cover plate (silver and black – not the ‘rubberized’ piece) and align it with the board. You can verify align- ment by seeing that the screw hole at the top left of the back cover is directly over the mounting 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, holding the remote with both hands press the front and back pieces together starting

. Replace the three screws that firmly 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 firmly at the top. Move to the middle and press again. You should feel and hear very definite engagement. Press firmly 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 n
