We have a big screen TV that has suddenly gone on the fritz a couple
of days ago.
It plays fine on channels 6 & 7 out of all available cable channels,
the picture is there and looks fine except for those two channels, a
'snowy' sound exists on anything but channel 6 or 7.
It even is this way when playing back tapes or DVDs through our player
when on channel 3, etc..
Does this sound familiar to anyone? My wife indicated today that on
one occasion, one of the channels was playing pretty clear albeit in
spanish with the commercials coming through in english. Weird as
Seems like a cable issue although the fact that we can't place the TV
onto channel 3 and play VCR movies or DVDs okay seems suspiciously
like a television problem.
unplug it and give it a ten minute rest.
plug in a portable set and use the big tv's actual cable connector to
check your cable channels.
look on the back of the big set to see how many other inputs you have.
get the make and model number. search for the missing operating manual
if cable works ok on portable set, plug in the big tv and reconnect its
cable. attempt to select a cable channel. if it's there, autoprogram
the channels into tv memory using autoprogram button or enter setup or
menu on remore control as needed.
if no cable channels are appearing, you will need to use the vcr as a
tuner and feed the video output into the tv video input with rca
connector. sometimes yellow. get the picture working first then connect
the stereo audio rca cables later.
sometimes there is more than one rf cable input connector on the tv,
sometimes the tv has a big menu of inputs which you must select from.
Is it possible you've accidentally set it to SAP (second audio program)
mode? That's often used for Spanish-language translations of English
material (such as the local news), but only the program is translated,
so they play the English (regular) soundtrack for the commercials.
Since you said it seems OK on all the other TVs in the house, it seems
really unlikely it's a cable issue.
Nothing stops a commercial from getting through. They'll send it with
a police escort if necessary.
You probably have the right answer.
A similar anwer might be that the tv got set on Antenna instead of
Cable. I have a VCR that goes to Cable every time I go to the
The problem with my idea is that channels 2 to 13 are the same
frequencies in cable and antenna. If the OP could change his scenario
that those channels work and no others do, we'd be in business.

me know if you have posted also.
SAP or some other audio mode is the highest probability. The channels that
work might be the only ones compatible with the mode but you shopuld not
hear static if it were just a mode setting problem. If it is an electronic
failure, my guess would be the audio decoder chip which decides if you
listen to mono, sterio or dolby etc. I am guessing the big screen means a
more recent model.
Have you called the 1-800 number on the instruction manual, those guys
won't be guessing and can tell you immediately if it is an electronic
failure requiring repair or just a mode setting problem.
How old is this TV? About 20 years or so ago, I had a TV that would act
similar to yours if the wrong cable mode was selected. These days, TV
tuners can be set to regular TV (antenna) or Cable. But the TV I'm talking
about had more selections than that. If you wanted to set it to Cable, you
had to choose one of 3 or 4 different cable modes. If you choose the wrong
cable mode, only certain channels would work, and all other channels would
have bizarre symptoms like you are describing. -Dave
It's possible to have a short or something somewhere along the cable
and have that act like a bandpass filter that might pass a couple
of channels and attenuate everything else.
Try running the cable directly into the TV tuner, without anything
else attached (like a VCR, cablebox, etc). If the problem is still
there, move one of your smaller TV's into the room and see if it
has the same problem.
It should be fairly easy to determine whether it's the TV, the cable,
or something attached that is causing the problem.
Just wanted to say a big THANKS to everyone who posted a reply to my
post here. In the past, I've unplugged the set, waited a couple of
minutes and plugged it back in when it's acted strangely but haven't
experienced anything quite like this. This morning after reading your
replies, I started with the easiest first and unplugged the set prior
to jumping in the shower for work. Upon getting out later, I
proceeded to plug the set back in and went through 'setup'. VOILA, my
problem went away and all was well... Thanks again, folks - I VERY
much appreciate your time.
