Answer to "Where can I purchase a replacement LCD?"The Harmony One LCD's from Harmonyremoterepair.com work very well. I have used two of these. Word of caution though, and this is stated on the repair web site. The replacement LCD is only good on the version 7.4 modules, and NOT for the 7.2 version modules. Before purchase you should follow the video guidance on the repair site to dismantle the remote and check the module version. Soldering skills are also required and the LCD w/ the Chip Quick soldering aid option is required to effectively remove the old LCD without damage.
