Things Roger Should Invent: check for signal issues before dispatching a tech

Since I moved into this apartment just over two years ago (!), I've had the same problem occur with my Rogers cable several times:

I get problems with video and/or audio quality on a seemingly random selection of TV channels.  I power cycle and/or reauthorize my cable box several times, and it doesn't resolve the problem.  I call Rogers, who check various things on their end then dispatch a technician.

The technician arrives, presses a mysterious combination of buttons that causes a bunch of mysterious numbers to appear on screen, and discovers there's a problem with one of the mysterious numbers.  (It might have something to do with frequency or signal - unfortunately, it didn't occur to me until I started writing this blog post to take notes.)  This problem has to be resolved centrally, so the tech puts in a report and tells me it will be fixed within a couple of days.

And then it's fixed within a couple of days.

It seems to me that they should be able to either check these mysterious numbers remotely, or have the tech on the phone walk me through the mysterious combination of buttons needed to produce the mysterious numbers and read them aloud over the phone, so they can confirm whether there are any signal issues that need to be fixed remotely before wasting my and a tech's time dispatching a tech to read numbers off a screen.  If there aren't clear signal issues, then they can dispatch a tech to see what's happening on-site.

Advanced option, since we do live in the future: when they detect that a customer is resetting their box (which my conversations with phone techs lead me to believe they can do remotely), Rogers computers remotely check that customer's signals, and if there's anything outside the norm they flag it for a human to look at.  Then, if multiple customers in the same area have signal levels outside the norm (which, as I understand it, has been what was happening in these past signal issues), they can detect it and do their remote fix before anyone needs to go to the trouble of calling tech support
