Nothing appears on the product display
If your system works but there is no display or it does not light up and appears blank, try the following:
Check for and install any available product updates.
For more info, see Checking the software or firmware version and Updating the software or firmware of your product.
Try new batteries in the remote.
In case the battery or batteries in your remote are low or have no power, replace them. Alkaline batteries are recommended over rechargeable batteries, which might output lower voltage. (Note: Battery testers are not always reliable since they might detect power but not indicate if there is adequate power for the remote.)
