We have tv with a dta box and a dvd/vcr combo hooked up to it. All was fine; dvd played, vcr played, all channels worked on the tv. Last week we lost power for about 10 minutes, it came back on, then we lost it again for about 3 hours. When it came back on, the clock on the dvd/vcr was just dashes so I turned on the tv and the dvd player to access the menu to set the clock and all I get is snow. The tv and channels work fine (via the dta); however the dvd player just produces snow. I didn't change anything cable-wise it's just that the power went out. I just spent about 45 minutes changing all the cables around (thinking maybe that would help) but . . . just snow. Everything is set back to the way it was when I first set it up. Even though the tv channels work via the dta do I need to 're-activate' the dta in order to get the dvd to work again? That doesn't make sense since the tv and channels work fine. What am I missing? Any suggestions would be welcome. Thanks.
