Question about Sanyo AVM-3659S 36" TV

1 Answer

Cable channels fuzz out

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. Stargazer

You need to go into the menu and set it for cable insted of air/tv. The television is only getting the 2 - 13 because on that setting, its as high as it goes.

I just bought the Sanyo you inquire about and am afraid of this problem. Did you fix it? How do you like your tv? Wish I could help with your issue and appreciate your time, Pogo.

When you hooked up the VCR or the Sat did you use patch cables? Sanyo had a lot of problems with tuners going bad. if you used patch cables you by pass the tuner so it will work

TV gets all channels, except 2-6

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.

make sure your got the right cable mode selected through the remote or autual switch on back of tv. if not it youll only see cable channels up to channel 13 that means in is standard tv mode or air. once you selected cable autoprogram and it find all the channels for you. these newer sets, dont bother with looking for a cable switch, its all done automaticly when you hit that autoprogram button but it would be in the menu under setup.

Can't get cable or any channels

Do you have another TV set you can test the cable with? It possible the TV you bought has a bad tuner. Or your cable line is dead.
