I bought a brand new Thunderbolt Display in 2011 but have not used it. Tried using it today and it does not come up when I attached it to the MacBook Pro and the iMac.

There is no light on the Macsafe power supply to the MacBook Pro and when I connected a mobile phone to the USB port, it was not charging.

I have tried several power sources but no improvement.
