Question about Logitech Harmony 890 LCD Remote Control
I have a logitech Harmony 890 remote. The battery is charged, by selecting a butter the remote lights up; however, non of the functions communicate with the TV. Any suggestions?
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.
