something about TV lifespan blah blah.
Wasnt interested to ask more as I don't have Sony speakers/soundbar.
Very strange since no matter what, you need to turn the TV on to watch hahah
And if someone doesn't have a soundbar, they would still have to use the TV's speakers
I tried searching the net for any issues with using the TV as the centre speaker - there were some reports that users had intermittent hissing sound where some rectified by replacing the cable that Sony provided while others had to get the technician to replace a circuit board (alleging that it's a known issue with a particular TV model)
Otherwise, I don't see any other reports of TV failing prematurely after using it as a centre speaker
Sometimes I take what the SE says with a pinch of salt
