MyHarmony.com plug-in or white screen troubleshooter

If a Harmony Activity doesn't power on, switch inputs, or control your devices correctly, then we can help narrow down the problem and provide a solution. If there are multiple problems, please focus on one device when answering these questions until it's resolved, then re-run the troubleshooter for other issues.

Important Note

Harmony has released a new software that runs from your Mac or PC desktop and does not rely on Silverlight or other plug-ins to be installed to your browser. It has the same capabilities as the website.

Download the latest MyHarmony desktop software.
