Why would a sky engineer see broken TVs?
That would be me, now why would I see a TV that is faulty, maybe because thats how you would actually VIEW the picture, unless you would prefer to sit there with your eyes closed and just imagine whats going on.
Quite often would get called out for a fault/service call which would transpire to be the TV that was at fault,and not the Sky system.
Of course I came across other brands of Tv that had faults(as well as the Sky boxes) but common consensus amongst engineers was Samsung developed the most faults, also Samsung and Sony to a lesser extent were lax at developing software updates to keep the TVs compatible with newer standards.
