I used to work for a cable company. I remember a coworker telling me a long time ago that one of the challenges they used to have was making sure the caller’s TV was tuned to the correct channel. So, the conversation would go like this:
“Please change the channel to 27” (or any other random number that isn’t a locally used channel)
“What do you see?” “Nothing…”
“Good, change it to 3, now what do you see?” “Nothing…”
“Good, change to channel 4” “It works!”
For those that don’t know, there was a long period of time where the auxiliary input into TVs was tuned to either channel 3 or channel 4. There was a good chance that the customer didn’t know which one was correct for their TV and would have assumed that it was already set correctly if you asked.
