Sorry for the delay in responding, if the base unit dosnt have any lights it suggests power isnt getting to the unit.
Check the power cable at the back hasnt come out, and that its switched on at the wall.
If it is, most likely the power supply has failed.
Let me know how you get on checking the plug at the back of the base unit and that its switched on at the wall, if it is I can advise where you can get a replacement power supply
I just wanted to follow up as I havent heard from you since you posted the query.
Do you require any further assistance?
