If the firmware didnt help, then it is a hardware issue. You probably got water in the battery compartment or something.

Anyway you should call Logitech support for a warranty claim. Or, you can do it by taking a look at the following link:

Hope I was able to help!

Please apply the following troubleshooting steps to get the LCD screen issue resolved:

1- Remove the battery from the Harmony Remote for 10 seconds and insert it back in, and test the remote to see if the screen is displayed properly. If this does not fix the issue, please proceed with the following steps.

2- Make sure you have the latest Logitech Harmony Software (version 7.6.0) installed on your computer.

3- Connect your Harmony Remote to the computer. Run the Logitech Harmony Remote software on the computer and Login to your account.

4- Click on the "Downloads" button at the top and select "Firmware"

5- Remote will go through the firmware update, which will put the Harmony Remote back to Factory Default with the most updated firmware. Then software will ask you to select "Yes" to update the remote and click on "Next" to do a remote update, which will take the information on your account with your Devices and Activities and bring them into the Harmony Remote.

6- If this Firmware Update process does not fix the LCD screen issue, try doing a Firmware Update in "Safe Mode". To do this; remove the battery from the remote, press and hold the "Off" button on the top of the Harmony Remote and insert the battery back in to the Harmony Remote. Screen will display "Safe Mode" and then please follow the steps 3 through 5 again.

If this doesnt fix the problem i suggest you contact logitech. when contacting them, do not tell them your son spit soda on it:

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.

Try this.

1. Log into the Logitech Harmony Remote Software on your computer
2. Click on the Downloads button at the top-right corner of your screen
3. Click on the Firmware button. Follow the onscreen instructions to upgrade the firmware on your Harmony remote
4. Once the firmware upgrade is complete, click on the Update Remote button
5. Test your remote.

Try opening the Logitech Harmony remote software on your computer, then log in. Update the firmware. Don't plug the USB cable into the remote until you are requested to by the program. It should recognize the remote and let you know, even if the screen isn't showing anything. Try to update and see if this helps.

Thank you, this worked.
