How can I replace the outlet for the cables on the back of my quasar SP 3234E TV?

A "freezing" picture sounds like something other than your television. Do you have a cable box or satellite box attached? They fail sometimes and need to be replaced. (You have an analog TV and "freezing" is a digital problem.)

The picture freezes and the sound is lost. Until the picture returns and the sound returns,this happens every couple of seconds.

If you actually have the Zenith model TV (B25A24Z), the trouble is not in your set. This model has only an analog tuner, and what it sounds like you are describing is digital pixellation. This is what happens with a digital-to-analog converter box when it gets a weak signal, with rain fade or heavy snow on a satellite dish antenna, or when a digital cable system has some signal problems. The converter equipment locks the last complete frame (or breaks up into blocks and freezes) and the sound is muted.

You'll need to look for the cause of your trouble in whatever is feeding the TV. If you have a digital converter box for off-the-air broadcasts, make sure you have a good antenna and all the connections are tight. If you have satellite TV service or digital cable service, you might need to contact your service provider for help in troubleshooting and fixing the trouble.

Sound not picture

A few questions:
Are you using this TV directly on a cable line of do you have a cable box or satellite receiver connected?
Do you have sound and no picture on the AV inputs as well, or only on TV channels?
Is there anything on the screen or is it completely black? Has the picture collapsed to a single line across the screen? Is there a picture but it's distorted?
Does the on-screen menu and channel number display properly?

With a little more information I might be able to help you with this.

RCA television suddenly has problems with cable reception

You have a bad ground connection somewhere. Either the cable has a break in the ground side or there is a connection problem elsewhere. Try with another cable if possible.

Problem with cable reception

Mmmm, sounds like the high voltage supply is toast. Recommend taking to repair shop; get an estimate, it may not be worth the money to repair.
