I have two TVs in my home. One with a digital box another with just a cable connection. I also have Rogers HighSpeed internet for my computers. On Sunday, when I turned off my TV without the digital cable box, all other systems reset. My digital cable box shut down and reset and my computer internet also reset. Any idea how/why that would happen?
Is this reproducible? Does it happen every time. Sounds a bit weird and might have been a coincidence.. But maybe your tv without the digital box sent a surge back through the wire and the other hardware shutoff to protect themselves.
