Harmony 890 screen is blank - Logitech Harmony 890 LCD Remote Control

SOURCE: 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!!!

this sounds like it is a hardware issue, try contacting Logitech through e-mail from the website www.logitech.com and sending an e-mail in.

try the following before contacting them:
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.
If this doesnt work, provide them with the following to make sure the process goes as smooth as possible:

The PID of the remote:
The P/N of the remote:
The PID of the RF Wireless Extender:
The P/N of the RF Wireless Extender:
Full Name:
Phone number:
Street:
City/Town:
Country:
Zip/Postal Code:

Please Note: The PID (Product Identification) and P/N (Part Number) for the remote can be found either on the underside of the battery cover, or at the bottom of the battery compartment (the battery might be covering it). Your PID number is a character code with a combination of letters and numbers, starting with either WL, WD, or LZ

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.
