1) Ensure the cradle is plugged into an active AC outlet and the LED light on the cradle is on. There is a switch on the bottom of the cradle to control the brightness of the LED, set it to the highest. Try different outlets if needed. Does the LED light turn on and stay on (does not blink)?
2) Remove the battery. Place the remote on the cradle and check the LCD screen. The LCD screen should display a 'White' screen with possible colors before going off. Try this a few times to confirm behavior. Did the LCD turn on briefly?
if no, contact logitech
3) Reinsert the Battery. Have you charged the battery for at least 3 hours? If no, please recharge the batteries for at least 3 hours.
if yes, contact logitech
4) Did the battery ever boot the remote? If yes, please continue troubleshooting.
if yes or no, contact logitech
5) Remove the battery. Check the 3 gold contacts on the battery to see if there are markings on all the contacts signifying it was connected correctly to the remote. Did the battery have markings on all 3 contacts?
if no contact logitech

if you have determined this is a hardware issue, contact logitech and provide the information below

Logitech does not have repair services. If you are out of Warranty - some people will take it to their local electronic store, but if you are still in warranty - contact them and they will replace the whole remote!

Logitech does not sell replacement LCD screens for Harmony remotes.

I would suggest buying a broken remote from eBay or somewhere cheap. However, keep in mind that attempting to repair your remote will void the warranty.

Hope that answers your question.

There is a setting that may need to be changed within the Xbox 360, to allow it to be controlled by a Harmony Advanced Universal Remote.

To configure your Xbox 360 to respond to a Harmony Remote

1. Using your original Xbox 360 controller, go into the Xbox Dashboard on the Xbox menu
2. Select "Console Settings"
3. Select "Remote Control"
4. If "All channels" is selected, select "Xbox 360 Media Remote”. If "Xbox 360 Media Remote" is selected, then select "All channels"

Your Harmony remote should now control your Xbox 360

if you can enter you tv set up screen,, plug you xbox 360 in and turn on, then run setup

Try a hard reset first. Remove batteries for about 10 minutes and reinsert fresh ones. If the lines still appear, there is a problem with the LCD screen. Contact Logitech support for an RMA.
