Question about Logitech Harmony 670 LCD Remote Control

1 Answer

Display on remote is not working, how do I reset

The remote buttons still work, but the display is blank; so I have to work it using my memory of which buttons are which. How do I reset it and get the display to work again? Batteries are new, it is not a battery problem.

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 that does not get the screen working, then it is something with the hardware that is defective. If this is the case, I would email Logitech.

Why is screen blank?


You never said if it worked with external monitor. You also didn't say if you tried the [fn]+[Fx] key combination on the keyboard to try and switch displays.
But, if you look at the screen closely, at an extreme angle and can faintly see the graphics then that means the backlight has blown out. For the displays with LED backlighting it's usually just a wire or circuit to repair. For the screens with CCFL (fluorescent) lighting it's a simple matter of replacing the inverter board.

Sharp comfort touch air conditioner screen doesnt show settings and buttons wont work after cleaning. help its hot!!!!!


Switch off the unit at the isolator or fuse box. Leave off for 10 mins to reset. When powering up again and it still wont work, check your remote control batteries are good. Also confirm you haven't "blanked out" the display. Some controls have a display or LED function which blanks out the display so that the lights are not bright at night time. (For bedrooms so that the light doesn't keep you awake) Also check that you have not pressed a "child lockout button" This will stop anything ..

My son bought an AOC LCD TV (model L24H898) last month and connected his laptop and XBOX to it. Yesterday we lost internet connection and the screen on the TV went blank. Now none of the button on the TV...


According to the manufacturer, to reset the entire unit do the following:
1. Press and hold "Menu" and "Channel +" on the TV. 2. Using other hand, press the power button. 3. A small screen should appear in the top left part of the screen. 4. Using the remote, select "Memory Recall" and select. 5. Power off and re-boot the computer 6. Run channel auto-scan to regain the picture.

Touch screen display broken


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. If you are not in warranty, Logitech does not provide repair services for Harmony products.


Hope that helps.

Remote won't work


Using a small test meter, check that you have 1.5v on each battery. Sounds like faulty batteries.
