The TV has perfect picture but no sound how do I get the sound back on


Are you by chance on the SAP audio channel instead of the main channel? You should be able to go into the menu and look at the audio settings. If you are on SAP change it back to main. Some stations do not have audio on the SAP channel.

Connecting rca tv model#F20352SF to a tv converter box


  • Connect ANTENNA OUT of STB to antenna terminal on rear of TV OR, for better picture, connect 3-wire cable to color coded L AUDIO, R AUDIO, and video outputs on rear of STB and connect other ends to L AUDIO, R AUDIO, and video inputs on rear of TV.
  • If STB connected to antenna terminal of TV, set CH 3/4 switch on rear to whichever channel is NOT used in your area.
  • Connect antenna to ANTENNA IN of STB
  • Connect STB to power and use STB remote to turn on
  • Turn on TV
  • If STB connected to antenna terminal of TV, use TV remote to select channel 3 (or 4).
  • Use STB remote to select SETUP and perform channel search.
  • Use STB remote to change channels.

My television set is stuck on one channel....the audio changes with the channel but the picture stays blurred on one channel...whats wrong with it?


Lots of possibilities. If you are using the remote, try also using buttons on the TV to change channels. If TV buttons work, the remote is broken or perhaps try changing batteries and cleaning battery contacts on the remote. If neither work, lots of other things to try. You may need to set preselect channels, so your TV thinks there is only one channel out there until you do. If you are on a cable box you just need channel 3 and change channels on the cable box. I can't tell what you mean by "audio changes with the channel" ... if you mean that when you try to advance channels, it increases volume and moving down in channels lowers volume that would be strange -- if you are using a programable remote it might not be set correctly (try another programming code). The "blurred" picture is probably symptomatic of having the set on the wrong channel, and if you could set channel it might clear up ... I'd start with getting channels to change. If you need more help, give the brand and model of TV, say if you are using a remote (original or programable), and what the 'audio changes' comment means in more detail. Probably worst case is that your tuner circuit is fried, but don't assume that without more diagnostic.

TV no sound but pictures ok, changed channels ok


The mts/sap function on your television might be enabled. Locate the audio settings on your television and make sure you are set for either stereo or mono. You may have an audio or mts button on your remote. If not this should be in the menu.

The cable company may have made a recent change and the tv may need to be channel buffered or you may need to complete another channel scan.

I can get a picture , but no sound on the TV . What am I doing wrong?


Many RCA TV sound problems are caused by SAP function being activated by TV station equipment that converts Analog TV signals to HD signals. Accidental pressing of the wrong buttons on your remote can also cause this problem.

The incorrect conversions causes the Audio settings to be changed from Stereo to SAP by the received signal.

Solution is to go to Audio set-up in customer menu and change settings from SAP to Stereo. If you find that settings are wrong, change them to "Stereo". Do channel scan if you are using the TV tuner/remote to select channels. Turn off the TV and unplug for 60 seconds. Check the settings again and reset if required.

This problem may re-occur when you select the VHF channel, satellite channel or cable box channel that is causing the problem. It is not a TV fault that can be repaired. The problem is caused by the incorrect incoming signal.

SAP is Second Audio Program, used for second language transmissions.

Second cause may be that the speakers have been turned off in the audio set-up menu.

Trying to connect Sharp VCA310X VCR to TEAC TV CTM5140; am only getting blue screen with audio; no picture! Have tried every possible combo with the AV cables (red, white, yellow).


I would suggest trying to change the channel, either on the tv or the vcr. Sometimes, if the channel is one off, you will get sound but not a picture. On the back of the vcr, there SHOULD be a switch to change it to either channel 3 or channel 4. You must match this up with the channel your tv is set for. I hope this helps, but if not, I hope you can get it figured out soon. Good luck! Der Strom
