My older sanyo tv has been having this situation where certain cable channels will go out randomly. It seems like the higher the channel, the more frequently it will go to the fuzzy screen. If we turn off the tv and wait for a couple minutes, the picture will resume like nothing was wrong. Changing channels is hard because you never know if changing back will make the tv go out. This problem never happens when we use the video imput, only when watching cable tv. I'm just trying to decide if this can be fixed, becuase if it isn't worth it, i'm just going to throw the tv away. Any help would be great, thank you.

Re: Cable channels fuzz out
I think you have a bad connection in the tuner.
The tuner is what decides what channel you get.
It's a small box inside your tv about the size of a pack of cigarettes. These have been known to develop loose connections or just go bad.
Some are pretty expensive depending on the type set you have.
Since your set is older and you want it fixed you'd better get an estimae first.

Your TV must be set in cable mode for channels higher than 69, and your cable provider must allow those channels to be received without a cable box. Menu, Channels, switch air to cable, run auto scan. If it receiving those channels unencrypted, it will find those channels.
Your cable box might not be sending signal out to the tv. Would have to call service provider to have them test your box. Or, you can try unplugging your cable box, and then plugging it back in. Make sure all connections are secure and settings on your tv are accurate.
In most cases when you set your menu ("tuner section") to cable, the tv will pick up all channels, but if you set it to "off air" or "antenna" (or whatever the other choice is labeled), then the tv will only go up to about channel 50 or 60. Are you using cable, dish, or an antenna on top of your house. If using cable or dish, then go into the menu on your tv and set the tuner to "cable". I am pretty certain that your tuner is NOT currently set on "cable" and that also there are no local "off air" channels in your area on 2 thru 6, therefore, you see snow on these channels. I have repaired hundreds of tv's and I feel very strongly that your problem is in your menu.
