Apple TV 2

you need to restore it, something you cant do using an ipad

Restore your Apple TV through iTunes - Apple Support

Be aware that the 2nd Gen is classified as obsolete so if the restore is unsuccessful or the issue persists then there wouldn’t be anything further one could do

No problem. The current models are the Apple TV HD and 4K, there has been no announcement of any future hardware in case that's what you were referring to.
