Can Buttons On A Harmony 890 Tv Remote Be Cleaned

I recently fixed two of my 890 Pro remotes past doing this, and I thought I'd share some tips.

1. Remove the battery cover and unscrew the 2 phillips screws at the back:

2. This is the tricky part: prying open the remote. In that location are eight large tabs along the sides and two small-scale tabs at the superlative property it together. The side tabs are very easy to pause, and you will probably break at to the lowest degree i. You don't need all of them to have the remote feel tight so don't worry too much, merely here's how to avert that.

Find some kind of thin plastic object (like a natural language) that can fit in the scissure between the summit and bottom. If yous care about the appearance of your remote make certain you lot employ something fabricated of soft plastic! Hard plastic or metal will fray the border of your remote. I recommend to start at the second tab from the height, equally you will not feel that area when holding the remote in case it does go chipped. You don't want to start with the topmost side tab since the top tabs are clamping the top together. And so accept your thin plastic tongue and jam information technology in at that place, pushing against the tab. At the aforementioned time, pry the remote open with your fingers and push the top to the side to effort to unhook the tab in guild to avoid breaking it. The meridian tab clamps over the bottom tab, so if you lot're trying to open a left tab, push button the tiptop half of the remote to the right while prying it open.

Once you lot accept one tab open, work your fashion effectually the bottom of the remote, and finally pull away the superlative.

3. Remove the circuit lath past unscrewing it. There are two screws in the middle attaching it to the bottom half of the remove cover.

4. Remove the power connector, use a minor flat screwdriver to pull away the 2 sides of the connector.

5. Pull off the daughter lath (on the 890 Pro).

5. Now you lot have admission to the circuit board. Here you tin do a couple of things similar:

- Supplant the LCD screen: On the dorsum side of the board, unhook the LCD connector. Unhook the four small white tabs that attach the LCD to the board. Slice the connector cablevision through the hole to detach the LCD screen.

- Fix the tilt sensor: on one of my remotes the tilt sensor broke. The tilt sensor consists of a fiddling metallic brawl encased in a cavity surrounded past four metal contacts. When the ball shorts two of the contacts the sensor is activated. On my remote, the pinnacle cover on the cavity opened upward, the metal brawl escaped and was rolling free within the remote. I simply put the ball dorsum in and snapped the sensor cover dorsum on.

- Reattach or solder whatever other loose components, like the USB connector.

- Fix broken/missing buttons: yous take access to the top half and yous can remove the tape and screws to replace missing buttons or clean information technology upwardly.
