The TV slowly runs through every possible television frequency, making a list of each available channel along the way. Naturally, that list needs to be updated every once and a while, and you have to start the scanning process all over again.
That means you have to rescan every time you move, every time you buy a new TV or antenna, and every time a local TV station changes to a different broadcast frequency.
As a result, all TVs are going to lose track of local channels slowly. The solution? Scan for new channels every month, or every time you notice that a local broadcast goes missing. Scanning or rescanning for channels is mostly an automated process. All you have to do set that process in motion through a few simple steps.
And while these steps are different for each TV, the process is pretty similar on every TV out there. Admittedly, this is a clunky, somewhat annoying process. Well, they do—kind of. A good radio signal is filled with a mix of loud and quiet parts musicwhile a bad signal is filled with monotonous static or silence. So, most radios have a built-in tuning circuit that simply checks the amplitude response of radio frequencies. In the next decade, ATSC 3.

Message 4 of 7Views. Same problem BUT Any suggestions? Message 5 of 7Views.I hooked it to my cable provider with a cable that hooks from my wall to my TV, and that worked perfectly fine.
I've recently moved and am now trying to hook my cable up to my TV in a similar fashion different TV provider but same set up and I'm having difficulties. The cable is hooked from my wall to the RF slot in the back of the TV with a separate cable box that plugs into the wall and also hooks up to the cable outlet in the wall, the same format it was hooked up in my old house.
When I go to the menu to run channel auto scan, it will scan for a few minutes locate about RF channels and then quit.

I'm able to get cable by plugging the YRW chords from the back of my cable box into the back of my TV, the only problem is is that I want to be able to hook my PS3 up at the same time and I can't through this method.
I was able to hook my PS3 up using the YRW cables and my cable through a cable that connects from my wall to the RF slot at the same time at my old house. I know I'm probably missing an incredibly obvious solution here but will someone tell me what I'm doing wrong.
