Logitech Harmony 650 Troubleshooting
Universal remote released in 2009. Easily identifiable by the Color Smart Display.
Buttons Not Responding
When you press a button, nothing happens.
Dirt in the Key
If there appears to be dirt or another object blocking the button, remove the button and clean the area using a Q-tip and some rubbing alcohol.
Physical Switch is Broken
If the problem persists after cleaning, the button switch may be broken and needs replacement. Check out the replacement guide
for how to do this.
Battery Drains Quickly
Even while not in use, the battery runs down abnormally fast.
If your batteries are leaking, remove the batteries and clean the socket before inserting new ones. If that is not the case the batteries may have also been drained and are in need of replacement.
Screen not Dimming Properly
Check to make sure that there are no buttons that are stuck by removing the batteries and massaging the buttons. If that does not work then try switching it in and out of safe mode a few times. If the problem persists then you will need to replace the screen. Refer to the replacement guide
for instruction on how to do this.
The remote resets all connections with other devices seemingly at random.
Faulty Battery Connections
Check to make sure that your batteries are well seated in the connectors. If they are, check to make sure they are not dead by replacing them. If the remote still does not work, try testing the battery connectors to see if they are loose. If they are, consider replacing/repairing
Often when dropped, the case may break in various places.
Test the face plate of the remote by gently pushing on it. If you see a a crack or a break then it might be time to replace
it, this is merely a cosmetic issue, but can become a problem when buttons can become dislodged.
The remote simply won't function or respond to commands.
Test the remote by viewing the infrared LED with a digital camera or a cell phone camera. Press any button on the remote and watch the screen to see if the LED lights up, and if it does not check to make sure that your batteries are not dead. If the remote is still not functioning properly or at all that could mean that the circuits have shorted out on the motherboard and it may need to be replaced. Use the Motherboard Replacement Guide
to help you with this.
