When it doesn`t respond I can shake it real hard and sometimes it will work.
Check with an other code to your device with the remote control.

Was it working before? Is it possible you selected the wrong brand of TV when programming the remote? Do you use a cable box or satellite dish with your TV (in other words, do you change channels by changing the channel on the TV, or on the digital box connected to your TV)?

Most DirecTV receivers are able to be controlled with IR (infrared) or RF (Radio Frequency) signals. DirecTV receivers are usually set to be controlled by RF.
To control a DirecTV PVR / Satellite, it needs to be set to respond to an IR Remote:
1. On the original DirecTV remote press the Menu button
2. From the Menu press Select on Settings
3. Select Remote from the left menu
4. Press Select on the IR/RF Setup button
5. Use the Up or Down arrows to change from RF to IR
6. Press Select to save
Note: Some models of DirecTV may have different steps to enable IR. You may need to refer to your user manual
Harmony Remotes only control IR signals. so this is not the issue. The Harmony Remote should control the tv. the original remotr needs to be tested for IR or RF.
The device we are working on that is not being controlled by the Harmony Remote could be operating on RF (Radio Frequency) signals. Harmony Remote can only control the devices that operate on IR (Infrared) signals. Most devices that work on RF signals can be changed to operate on IR signals, and this usually could be done by changing the remote control command mode to IR from RF.
Please follow the steps listed below to test to see if the device is being operated on RF or IR signal:
1- We need to use the original remote for that device to complete this task
2- Using your hand or a thick and wide object (wall, pillow, book...), cover the top part of the original remote. In other words block the direct positioning between the original remote and the device.
3- After you cover the top part of the original remote (or used an alternate way to block the direct communication of the original remote and the device), try pressing the buttons on the original remote to see if it can still send commands that can be received by the original remote. You can try powering on/off your device using the original remote when the original remote is being blocked by your hand or another object.
4- If you still can control the device using the original remote without a point of sight, your device is being operated on RF signals. If you cannot control the device without a point of sight, then it is IR operated.
5- If the device is RF operated, please change the command receiving mode to IR rather than RF and test the Harmony Remote.
6- If the device is IR operated, please contact us again by replying to this email and let us know if none of the commands or some certain commands are not working for that device.
You can usually find the information on how to switch the device to be operated on IR signals rather than RF signals, through the user manual for your device, or by contacting technical support of the manufacturer for that device, or even sometimes reaching the information simply by doing a basic research over the internet.

Did the behavior of your remote change or have you just started using the remote? If this is an initital setup, ensure that you have selected the correct model numbers and that your setup configuration is correct in the Logitech software. Many problems have been resolved by going back to the software configuration and making sure that all of the devices and mappings are correct. Assuming the programming is correct and things were working properly at one time and no longer are then you need to determine if the issue is a physical problem with the button activation (key presses are not making contact), or a software problem (corrupted programming). So here are some things to look
for:
When you press a key, do you see the 'transmit wave' icon appear at the top of the LCD screen? If so, then the remote is registering the key press. This means that the physical operation of the button is ok, so in this case, your issue is probably firmware/software related. You should update the remote's firmware and then re-load your settings. Both of these procedures are done using the Logitech software. If, after doing
a refresh of your firmware/software, there is still a problem, you can try mapping some of the hard keys to 'soft' keys on the LCD screen. So, instead of using the "Guide" button, you have a "Guide" option on the screen. The link below will explain the process for re-mapping button functions (it describes the process for the 880, but it should be the same for the 890). Hope this helps!
