You probably installed the batteries facing the wrong direction. Therefore, the remote is not receiving any power from the batteries. The + (positive) end of the batteries should be touch the solid metal tab.

Screen went out now remote does not, come on, control tv, or hook up to computer.


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.

Display problem


If formatting your phone doesnt help there are three possible problems in order of priority (1) your screen is gone and needs replaced (2) your ribbon cable is gone and needs replaced (3) phone needs flashed, I have repaired the first two above on many samsungs with this fault! Not an easy job! Hope this helps.

LCD Screen is blank


Had the same thing:
Step 1 - remove the battery for about 60 minutes. There seems to be a little energy store in the unit and just taking out the battery, counting to 10, and reinstalling it does not work.

Step 2- Do a software update upgrade from the Logitech site. The new firmware level seems to have fixed the base problem.

If you just take the battery out and put it in, it does not work.
If you take the battery out and just hook it up to do a software upgrade, it does not work becuase the remote gets power from the USB commenction so it remains "hung"

The most disturbing thing about the whole event for me was the number of people that had the problem occur about 12 months and 1 day after purchase....ie when it was out of warranty!!!
