We cant change the channel or hear the audio on the tv, but hear the audio just fine on the radio and dvds. The remote doesn't change anything, just put in new batteries. Thanks

In that case the tuner - the part in which the cable plugs in and in where the tv channel is selected, the data extracted and separated in video and audio - is defective and it will have to be replaced.
The part is quite cheap - $25 - but its removal and replacement is a complicated job (lots of very fine solderings required) that it would be best if you would leave it to someone with experience. You will probably have to take the tv to a repair shop, it will all cost you around $150.

I have a sony trintitron model kv20fs12 that i just bought used.A few of the channels have audio only during commercials. When the show comes on it has no sound. One channel has background noise such as...


Check your TV's audio settings and make sure it's not set for SAP (second audio program). You'll probably find it's turned on. On many channels or programs you won't notice anything since the broadcast doesn't include a SAP signal. But if the signal's there, the set switches to that sound channel and you have the trouble you describe.

The problem you might run into is that you often need the original remote to control the audio settings. I don't remember for sure if your Sony model has front-panel menu control. I believe that series does, though. (The remotes included with most TV sets usually have a single button to control SAP, which is often how the settings get changed in the first place. Someone hits the button and doesn't know it.)

Hope this takes of your mystery sound! Thanks for using Fixya.

Tv audio feed


You most likely have the SAP mode activated. Look for a button on your remote or an item in the on-screen menus of your television called MTS or SAP. You want to set this to "Normal" or "Stereo" (or even "MONO") mode to hear the regular television sound.

If it is in SAP (Secondary Audio Program) mode, as I believe yours is, you will hear other audio. Often this is a translation to another language, such as Spanish, and other times (notably with PBS stations) it is an unrelated audio (often music) feed.

Input problem


If you have the original remote, hit video, source, or input button, if it dont have them, then try to change the tv to channel 00 (zero or zerozero), if not then the channels might have to scroll to it, from channel 02 down to make it loop, if it goes to the next highest channel, then you need a remote. It may be set in the menu options to have the video source not saved to your list of saved channels. when you scan the channels, the tv might not look for the A/V source (audio / video), maybe just the RF source. The 3 DVD RCA wires are 1 video and 2 stereo, one stereo for left and one stereo for right. The TV has only 2 , 1 for video and 1 for mono 1 channel sound. This wouldnt have anything to do with why you cant use the DVD player. but try that with the original remote (or a universal remote that is set to your tv set that has either video, input, source or something similar. It is what tells the tv to change from the cable source (RF) and the AV source (the Red White and Yellow plugs, in your TV's case, 2 plugs, one yellow and the other either red or white or something). Dont really know how to explain it much more but hope it helps.

You can check the remote by holding it very near an AM radio. Have the radio turned on and tuned about the middle of the AM broadcast band and push the button on your remote. You should hear a popping sound come through your radio speaker. If you can't hear anything, try moving the remote around and tuning the radio. If all fails then the remote is not working. If you DO hear the popping sounds then you have a problem with the IR receiver in you TV. There's a little plastic "window" in the front of your set where the IR signal enters. If dust has collected on the inside this could block the IR signals from entering. Also the IR receiver itself may have gone bad. The remote for this TV has to be an exact replacement. I've had this problem too by trying a substitute. Stargazer
