HI. So there are a counple of things you will have to ensure for the connectivity to be successful.

1. You are not connected to the internet via a router
2. You are not on a wireless network

4. Your USB cable and port are good, and the remote is not connected to a USB hub but right into the compter.

Now, please do the following:

1. Uninstall the software
2. Download it again at http://logitech.com/myharmony
3. Install
4. In your computer's add/remove programs, uninstall the Logitech Desktop Messenger
5. Take out the battery, press and hold the "OFF" button, and re-insert it. The remote will display "Safe Mode"
6. Connect your remote and log in to your account
7. Click "Downloads" at the top and select "Firmware". The firmware on the remote will update.
8. Click "Replace Remote" to conduct a connectivity check.
9. Update the remote.

That should get the remote working. :)

Ewaynuworld: Remote works but blue screen does not show anything anymore. Right now I'm able to use remote because I remember the buttons (no words show at all).


HI! Here's what to do if your Logitech Harmony remote's LCD screen has gone blank.

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.



If the screen is still blank after you complete these steps, then it is a hardware issue and you should contact Logitech's wonderful support team, given that the remote is still under warranty.

I have a HK TC30 remote control that will reset itself, displaying "Testing" and then indicates that the remote thinks all devices are off.


Try re-loading the firmware again through safe mode. 1. Take out the batteries from the remote. 2. Turn on your computer and hold the off/on button and connect the USB cable to the computer and remote. 3. The remote display should say "Safe Mode Requested". 4. Start the HK software and login, then click on Support. 5. In the download section, click on firmware and then proceed to update the firmware again. 6. After you update the firmware, you will need to re-download your configuration again and update the remote.
