Question about Logitech Harmony 550 Remote Control

4 Answers

Blank screen on the Harmony 550

One minute the remote was displaying all the needed messages and next nothing is displayed.  I changed the batteries and that did nothing.  Everything continues to light up but there's nothing on the screen.  Even the programmed automation works but I'm doing it from memory and not because I can see anything on the screen.  Any idea what's going on?  Is there a way to reset the screen without losing my programming?

    Me too - blank display, but backlight is on.

    Ditto. worked fine last night, then poof - lights are on, but nobody's home. And as well, the remote works fine. Or I should say it DID work fine until I followed Logitech's advice to update the firmware. The remote is now stuck in safe mode and cannot be detected by XP any more.

I had the same problem - my kid stuck it in her mouth and then the screen stopped working. I was finally able to fix it by doing the following:
1. I took the remote apart by
a. taking out the four screws under the battery cover.
b. then, I used a small slot screwdriver as a wedge and ran it up the length of the edge of the remote while prying the top and bottom apart.
2. Once i had it apart, I took a blow dryer to it to blow out any dust and get rid of any moisture
3. I put it back together and it was in Safe mode
4. I took out a battery, held down the #2 button, and put a battery back in and got the "Update Successful" message
5. To my surprise, the remote was fixed.

This is a known issue. Logitech didn't even blink when I submitted a warranty request (WAY outside of warranty) No "try new batteries" or "let's reset the remote and put in in safe mode" - just a straight "we'll send you a new one"

They blacklisted my old remote so that I didn't need to return it, and shipped a new one right to my door.

For that reason alone (nevermind the fact that I own a slew of other great Logitech stuff) I have become a lifetime customer of theirs. Gotta love a company that steps up to the plate when they know one of their products is causing grief.

Well, I finally put together what worked for me:

1) pull a battery.
2) hold the power button down when you replace the battery - this should FINALLY get 'sefe mode' to show up on the remote
3) update remote

You may need to keep the battery our of the remote for 1 hour or so.
You may need to do this multiple times.
You may need to press power - OK - 0 <zero> at the same time before you do this (This is only if all else fails and you are really desparate and want to try anything. Try it with the batteries in only, Try it with the batteries out and hold all three down while you plug in the USB cable).

I did these various steps multiple times and it finally worked. Try the 3 steps top down and then with each of the alternatives a couple of times for each alternative.
Use the 'Power' - 'OK' - '0' sequence as a VERY LAST resort - this really messes with the remote and may cause it to get worse and require you to do the steps many times before it finally works.

Remove the battery and allow the voltage on the circuit to fade off. now reset the battery and see if the remote works. If there was any battery leak then the pcb can be damaged due to corrosion. please check this link for tips to repair:

MY REMOTE DISPLAY STAYS BLANK EVEN AFTER CHANGING THE BATTERYS WHAT SHOULD I DO NEXT(LOGITECH HARMONY 550)


My advice is to call Logitech. They may replace the remote or give you a discount on a new remote. The LCD screens on these remotes have been known to fail, and it's a hardware issue so there is not really much you can do to fix it.

I have the Harmony 550 remote and it only displays the 'welcome to your remote' message on the screen. I have followed the advice of other posts to take out the batteries and massage all of the...


Hi.

Perhaps you do not already have the Harmony software installed on your PC?
If not, it's on the CD and you will need the USB cable to connect the remote to PC, but that comes much later after you have constructed a configuration on your Logitec account. Then the 550 should certainly be able to show more than just the welcome message.

You don't really need the CD because you might as well download the latest software version from the Logitec website for 550, install it on PC, and get the full instructions there.

Next register using the software on PC and check that you have the the latest firmware according to the instruction manual. The on-screen guide on PC will lead you through making a configuration for your devices.

Regards
Chas

Hey, try doing the following:
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.


That fixed my 550 a couple of times. Seems that a firmware update will cure most ailments.

Hope it helps.

Blank screen but backlite is on


Had the same exact problem. Blue screen, no text, but remote worked ok - if you could figure out which buttons did what. Tried every solution posted online - battery pull for 10 sec, battery pull for 1 hr, and battery pull overnight. Tried updating software, firmware, but nothing worked. Found a replacement screen on ebay for $26 shipped, replaced it in less than 5 minutes, and works great.
