Remote TV Service

It is unusual.  The signal for TV antenna just went out.  At first, I thought it was the Samsung TV.  I called Service Center.  Nowadays, it is very high tech.  The call center can do remote diagnostics.  There is an option on the TV to allow remote control.  Then a pin is given and from the call center, they take over the TV.  It is like science fiction shows where the TV can be use to spy on the occupants.
