Remote infrared light are not working

Check the remote control for its infrared emission. Check it with fresh batteries. If it is found OK, check and replace the infrared sensor inside the TV. If you wish to get some details; check the site linked here. It has details about how to check a remote control; by one among the post. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/

update the firmware on the remote to get it out of safe mode and working again.

- connect the remote to your computer and launch the software
- click downloads at the top of the screen
- click firmware
- update the remote

if the firmware didnt fix it then it's a hardware issue. I would call their wonderful support team to get it replaced if you are still in warranty.

Try pressing down on the remote, and wiggling it around. It's just that the pins are not making contact I suspect.

If pressing down helps, you can fasten it on with a elasitc band or something so that it keeps charging. Also, if it is still under warranty, I woul advise contacting Logitech's wonderful support team to get replaced.

Hope that helps!

To check to see if your device is controlled by a RF (radio frequency) or IR (infrared) remote:

Power the device on manually

Cover the front of the original remote that came with the device with your hand

Press any button on the remote that you know the device would respond to normally

If the device responds even when your hand is covering the front of the remote, the remote is RF and the device cannot be controlled by the Harmony remote


Another test that can be performed is using digital camera:

Using any digital camera, even one on a cell phone, camcorder or webcam, look through the screen of the camera at the front of the remote

Press a few buttons on the original remote

If you see flashes of light as illustrated, the remote is IR and the Harmony can control it. If the remote does not flash, this original remote is an RF remote and the device cannot be controlled by the Harmony remote

For comparison, try the same steps with a remote control that you know is working correctly, such as the original remote for the TV, or DVD player. You should see the IR emitters flashing when performing this test.

You will need to completely exit out of the Harmony software and re-launch it. To do this:
1. Quit the Harmony software
2. For Windows base PC's, right click on the Harmony icon from the system tray and click on Exit
3. For Mac, quit the software by clicking on Logitech Harmony Remote Software menu at the top of the screen and then clicking on Quit 4. Logitech Harmony Remote Software
5. Open the Harmony Remote Software

You should now be able to login.

After forcing my open, I found two screws more. Located at each side of the "activity" button - hidden beneath a the class covering the lcd-panel and framing keys. It is attached with double-sided tape. Rip it of - and your remote will look much better than mine...

Sometimes you need to go into the menu page for the device that doesn't work and you need to "learn" the keys to the new remote. "Learn" meaning pressing the buttons on your original remote with the Infrared part of the remote facing the Infrared part of the new remote. This will help the Harmony remote duplicate the signal to the device you want to operate.
