Logitech Harmony Touch Troubleshooting
This troubleshooting guide will help you diagnose problems with the Logitech Harmony Touch.
''When you press a button on your device and the remote does not influence the connected device, it may be an issue with the button response and feedback."
If the entire button board is non-responsive, try replacing it with this guide.
If buttons are stuck, there may be something below the button physically preventing the button to press. To fix this, remove the button and make sure that there is nothing obstructing it. You may need to clean off the area under. Once this is clean, put the button back into position.
If your LCD screen in non-responsive or cracked on your device.
If your Logitech Harmony Touch screen is defective try replacing your screen using this guide.
If the battery in your device does not hold charge for a normal amount of time.
Make sure that the device is either plugged in to a power source or placed on the charging port. If the device is plugged in the LCD screen will turn on and will show a lightning bolt with the words"Charging," if it is charging.
If this is not the case... check the micro-USBadapter/cord to make sure the wire is intact. Your adapter may be faulty and you can purchase a new charging port at this site. You can check your power chord by plugging it directly into your Logitech Harmony Touch and computer or wall.
If your battery is either not holding charge or not working correctly
If your power adapter is working correctly (reference faulty power adapter) and your battery is still not working correctly, your battery is most likely the problem. Replace your battery using this guide.
If your remote commands are not responding in the adequate amount of time
Click on the Device's "More Options" and select "Adjust the delays (speed settings)" then choose inter-key delay: 300 ms and inter-device delay: 300 ms. Keep lowering in increments of 100 and see if your remote is still working.
