BT Featureline phone, led display not working

Do these displays have batteries to meke them work normal again

I think the LED directly gets the power from the phone line. If the LED is not working but the phone is working, either the LED needs to be replaced or maybe the whole unit needs replacement.

You might need to call the support team and check your options on this. 

Good luck.
