The new TP270 isnt actually really new ?
TP270 has been discontinued for many years, and Siemens wont sell you are replacement.
You can send a defective for repair. I think, not sure if they will do it, if they do it will be very expensive. So I am guessing you have bought the new TP270 from some 3rd party.
If you have bought the new TP270 from a reseller then it is possible that it actually used, maybe refurbished, or maybe merely removed from some machine without testing.
edit: If it did not come in a new and sealed box, then assume that it is not new.
