Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Device freeze how to I reboot/unfreeze Harmony 550


Hey, try doing the following:
1. Remove the battery, press and hold the 'OFF' button, and re-insert the battery. The screen will display 'Safe Mode!', or the 'Activities' button will be lit.
2. Connect your remote to the computer.

3. Launch the Harmony Remote Software, and log in.

4. Click "Downloads" at the top and click "Firmware".

5. The remote will go through the firmware update.

6. Select "Yes", and click NEXT to update the remote.


That fixed my 550 a couple of times. Seems that a firmware update will cure most ailments.

Hope it helps.

No responce from a harmony 550 remote


First I would remove the battery for 10 min then replace. If that did not help, I would hook the harmony back up to your computer and update the remote. If that does not fix the problem then I would down load the firmware and then update your remote. Even if your current firmware is up to I would still download and update the firmware.
Hope this helps.

The screen disply reads "harmony safe mode", we purchased the remote with our tv @ 1yr ago, but recieved no tech papers or cables to hook to lap top. Thanks Steve


The Harmony 550 uses the same UB chord as most digital cameras. It's a Mini-USB .

Also, you will have to download the Harmony software from http://logitech.com/myharmony.

Now, please do the following to get your remote out of safe mode:

1. In the software, click "Downloads"
2. Click on "Firmware."
3. Update the remote
