I and thousands of others have had the same problem. My remote is about a year and a half old. Take out the battery and leave the battery out for a good two hours. There are capaciters in the remote that hold a charge for a long time so it is important to leave it out for this period of time. Then put the battery back in (at this point your screen will probably be visible again), connect it to the computer, and re-sync the remote with the configuration stored on your computer. The screen will come back on some 890 remotes after this. Mine did but only for a short period and now its back to just showing a blank blue screen. At the end of the day Logitech uses substandard components in an effort to generate service repair revenue or get you to buy the latest and greatest of their product. Shameful but likely profitable for them.

    Ok, just say another post on this site about the same issue: Mine is out of warranty so I took mine apart like the guy suggested, and walla the screen is back. I'll report back if it stays this way for a while.

    Note once you get the two obvious screws on the outside of the unit off you'll need a very thin screw driver to wedge between the two pieces of plastic to get it apart. There are four hidden tabs on each side of the remote that hold the two half’s together. If you use a bright light you can see them though. Just position the screw driver on top of each tab and push and with your finger nails pull the two pieces apart until it that tab pops away from the lower half. Do this for each hidden tab and then you can fully open the unit.

Screen stopped working today. phone rings but I can't see anything on the screen Can I fix it?

Cell phones are VERY hard to service. The problem with your phone is most likely related to the back light. Time for a new phone.

Harmony 890 just went dead. Nothing. Nada. Not

I have an 890 also. I've found that the remote doesn't always charge when it the charger. I have to put a rubber band around it and make sure it shows that the the battery symbol on the display is showing that it charging. Or the battery isn't taking a charge anymore and I'd try to replace it. Doesn't really hold a charge very long either.

Have blank screen, but remote works. Harmony 890

If the screen is still blank after you update the firmware in safe mode, then it is a hardware issue and you should contact Logitech's wonderful support team, given that the remote is still under warranty.

Hope that 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 when it was out of warranty!!!
