If you have 'lazy' or defective buttons on your Harmony 880/890, or Harmony One/900, then you generally need to have the underlying tactile button dome(s) replaced. Sometimes, cleaning the underside of the dome and the corresponding pad on the PCB with a product like DeoxIT D100L can take care of the issue, but often, cleaning alone is not effective, as the tactile dome itself has become deformed or has microscopic pitting or corrosion. Some do-it-yourself procedures that you find on the web include 'building up' the top of the dome (or increasing the length of the plunger on the button cap), in an effort to increase the force that is applied on the dome. This approach, though sometimes effective, typically only works temporarily (if at all) and, in fact, exacerbates the problem over time, as the added force deforms the tactile dome even more so. Eventually, the button will stop working altogether. Instead of opting for these less-than-perfect solutions, it is best to simply replace the defective tactile dome(s). We offer button replacement services for the Harmony 880, Harmony 890, Harmony One, Harmony 900 and Harmony 1100. But, if you want to try replacing the problematic buttons yourself, you can purchase a defective logic board and 'harvest' the button domes from the defective board. We don't sell tactile button domes for do-it-yourself projects, since there is no way for us to ship them and keep them in 'clean room' condition. If you decide to use harvesting, we recommend pulling the tactile domes from the numeric pad portion of the boards, since these are more likely to be in good operating condition. Stay away from using any buttons that are 'high use', like the Vol/Chan buttons, and don't use any buttons that line the perimeter, as these tend to receive more potential exposure to dust, spills, etc. Keep in mind that opening your remote to do this kind of repair, does entail some risk and you need to be especially careful that you do not disturb other components. Please use the guides and/or videos that are on the Support Page to assist with opening your remote and always feel free to contact us if you have any questions or need guidance. We are always happy to help!
