Tv getting snow & static sounds on all channels.

This TV, I believe, does not have a digital tuner. If you're trying to pick up channels off the air with rabbit ears or a rooftop antenna, you'll need a digital converter box. Without one, there aren't any channels for it to tune in, so all you'll get is snow and static.

If you have a converter, or are using this TV with a cable box, satellite receiver or a similar device, you may have a bad connecting cable. Be sure the cable is firmly connected and that the center pin isn't bent or too short for a good contact. It should extend an eighth of an or so past the end of the connector. Try another cable.

If this set has been working properly and the trouble is new, something is up with the tuner. It may have been damaged during a storm or from power line problems. Poor solder connections may have developed on the circuit board. Other electronic failures may have occurred. If the trouble appears to be inside the TV, it's probably not worth repairing. The replacement cost of a small TV would be not much more (if not even less!) than the labor and parts to fix it.

I hope this has helped. if so, please take a moment to give a thoughtful rating. Thanks for using Fixya!

Hello
If there is snow in all channels in your TV, your TVs tuner may be in trouble. Not may be, should be. Check for any antena problem is there or not. If you are using external yagi antena, reorient its postion and observe whether the snow [otherwise we technically call it video noise] reduces or not. Check for any loose conatct on your TVs antena socket, or any wire loose is there. if all the above are correct, it tuner is faulty and should be replaced.
For that you should open the TV. Tuner can be located very easly as it will look like a box, diretly soldered to the printed circuit bord of your TV. You are giving signals at the input of this box type tuner, which comes outside your TVs back as antena socket. Desolder it, and go for a similar type and number. There are so many types, and looks alike, but are different in functions. Check whether its leg confuguration is correct or not. You just buy the same number an type, the number and type is usually marked on it. Ok
Wish you success
