Lost some channels - Sylvania LC420SS8 LCD TV

I would be talking to my satellite or Cable provlider. Doesn't sound like you have a problem with your TV because if it will pick up one channel it will pick up all them.

Check your antenna direction (antennaweb.org or tvfool.com are good sources for signal direction). When I lose channels, it's a digital signal that came in with "bad signal" strength and my external antenna has rotated in the wind. (Oddly another TV in the house doesn't seem to lose the signal as easily even though they share an antenna.)

Also check the weather conditions and time of day. I've gained distant channels when scanning near sunrise or sunset and lost others during thunderstorms.

I hope this helps.

you are doing well to have any channels at all as all the other people have lost all sports and movies so i would delete the channels that are scrambled and then rescan you must delete the scrambled channels before you rescan

I can think of a few humerous quips for this question....

Not sure how the wind could remove a channel unless the antenna has shifted. Like 2 and a half men, its better to call the antenna guy!
they have a signal strengh meter to tune it into the best position
Otherwise try rescanning the channels to tune it all back in (with the remote)

Thanks for using FIXYA

I think you need to get Sky because it will give you 100% coverage of all terrestrial channels. You may need to retune the television otherwise just get sky

go on up the channels mate its under a number satanta 123
