Question about RCA P46924 46" Rear Projection Television

1 Answer

Static audio on certain channels

It is strange and has been going on for the last year or so. I will be watching the TV and all of a sudden it will just stopping audio. Everything else is fine IE video, remote TIVO and VCR. The sound goes out so all I an hear is static. I can unplug the TV wait a few seconds, plug it back then turn it back on and all is well for awhile. Some channels like discovery go out more than others(some not at all like ESPN, luckily!!). I have tried everything I can think of so any suggestions would be greatly appreciated. It is sooo annoying. Luckily I have a 10 year old boy so I make him plug and unplug but he would REALLY appreciate assistance. I have tried other plugs but no good????

    I have the same problem. My picture is clear, but there is no sound. I had a repair man out about 5 years ago and he replaced some "sound" device saying that it gets fried after the TV is moved so much. Cost around $300 to have it repaired. What are my other options?

Try tapping on the different boards and see if the sound comes back while you are doing it,use a wooden or rubber handle and be attentive to where you tap the chassis and that way you will know where the resoldering is needed wheter you do it or you call someone to do it,try following the speaker wires and they will lead you where the sound is processed but also try to tap on the tuner and that is the silver box where the antenna screws in,by now your set will also have a few other overheated areas that need resolder too.The back will be remove and the set will be on ,dont let your boy touch anything and be careful when you are doing it.Let Us know if you need more information.

High audio static on all but one channel of my RCA TV

had this problem for a while only just found the cause, its either your tuner flipped out which means you just neded to retune the tv and it should be fixed if not that there was this setting i found still not sure what it is or means but you could select these letters i think there was S, BG and some other ones but i changed it to the top one which was BG and it fixed the static sound with the clear picture problem just stuff around with the channel settings and see if you have that setting hope that helped

Very Strange Audio Problems on Cable Channels; No prob w/VCR

Mike, before you decide to pony up the money for the hdtv take the thirteen inch set in and connect it to the same coax cable that is currently connected to the set with the audio issue. If you have clear audio the issue is definitely with the set. If not try replacing the coax connectors behind the wall plate, the barrel in the wall plate, and the coax from the wallplate to the tv. I am curious if the audio is clear when playing a DVD, VCR or Xbox? Hopefully we can isolate the problem. Thanks for using Fix Ya.

Audio problem... channel with no sound

make sure your S.A.P feature is turned off. S.A.P. stands for separate audio program.


Hi Suezie,

The problem is most likely your SAP being turned On.

SAP was created for audio programing including translations into a 2nd language. On nearly all sets, the SAP being ON will essentially select an alternate audio stream and will de-select or mute the main audio from the channel your are viewing. However not all TV stations have SAP enabled.

I am the Chief Engineer of a TV station in Denver, CO. We are not using SAP so if you selected SAP while watching my station you would get noise or static. There would not be any audio there.

Go to the front panel of your TV and select the "MENU" function. Step through the menus to Audio features and De-select SAP or Enable your main audio and this should take care of the problem. Alternatively you might be able to unplug your set for a period of time and it would reset itself. I used to get calls from elderly viewers when the set wouldn't pick up the UHF TV stations anymore. These were always after a power failure and the set had defualted to factory settings,

Different set manufacturers use different menu schemes and withou a password feature, these menus are so simple a small child playing with those fascinating buttons can change them for you to something you really don't want.

Good luck and write back if you can't find it. The set manufacturer and model number would help me look up a menu tree for your TV set.

Thak you,
Bernarr Howell

Strange audio problems

called a tve repair man tha is a buddy of minr hr had me unplug the tv to reset the ic ship and it worked !!! thanx and good luck

White Noise Sound

Your problem is somewhere between the tuner and video detector circuit. The signal entering your TV carries: video,red color,and blue color as well as sychronizing pulses for color and horizontal and vertical deflection ( actually vertical sync. is derived from horizontal sync.) along with burst pulses to synchronize the color. After all these, the sound is an fm signal entwined with a pilot signal for stereo audio. WHAT a mess! After the audio passes through all this, it is detected and sent to the audio processor. If any frequency has drifted away from it's value then you loose the sound. SO... your problem could be in any of the tuned circuits or in the audio processor IC (chip). Any component changing value could creat this problem. Most likely the audio processor IC. You'd need to have the set checked out by a tech to find your problem. Stargazer
