Question about RCA P46924 46" Rear Projection Television

Open Question

No sound - RCA Home Theater Projection TV.

I have an RCA Home Theater Projection TV. The sound went out in the middle of a cable-broadcast show. We had not touched a thing on the set or the remote.
The TV is definitely not on mute, and the TV volume at about 1/4 of maximum.
You can hear white noise when you turn the volume up to max.
All the cables (co-axial and jumpers) are pushed in tightly.
There is a DVR/VCR combo connected between the cable line and the TV. There is no sound when we play that unit either.

I rocked the unit back and forth gently to pull it out from the wall so I could see the back.
The only other time we have had trouble, the repairman said there was nothing wrong except an intermittant loose connection. The last time we had this particular problem, the sound came back on by itself.

SOURCE: TV will not turn on

Probably needs a new HV Splitter block, they are very difficult to replace and can usually be accessed thru the front behind the speaker grill and behind convergence board.

SOURCE: no sound when connected to dvd player

If it's only connected with component video cable (Red, Blue, Green) cable set then no audio has been connected. You will still need to run a set of audio cables (usually White and Red). The other option is to use Composite cables (Yellow, White, Red). A composite cable set has the video on the yellow cable and the audio on the white and red. Component video breaks the video into the three channels.

I want you to know that I'm not paid for this, I just like trying to help. If I've misunderstood your question or this information does not solve your problem I'd be happy to try to help more. If you do find this information helpful I hope you'll give it a positive rating. Thanks and good luck.

SOURCE: I have an RCA rear

it depends on how you have the box hooked to the tv, is it via cable (co-ax) connection or rca (red yellow white) cables ? You may have the audio hooked wrong or it may be a blown input in which case switch to a new input on the back of the tv (possibly the one you used for game systems). If ur using a co-ax connection from the box try rca cables and if ur using rca try co-ax. If none of this helps call ur cable provider and tell them the box doesn't have any audio and u know it's not ur tv. Usually they will come fix it 4 free and try n educate you to what went wrong.

I have a RCA RTB10223 model, and my problem is I can get the surround sounds to work with a movie in, but its not working with the regular TV. What do I to get it to work?


That is because your movie is in 5.1 surround or better. Over the air and cable broadcasts are not always broudcasted with surround sound, there fore you will not always get it.

This reson you are not hearing any "TV AUDIO" through your RCA surround system would be due to your tv sound output not being connected to an audio input into your surround system. You can hear DVDs,CDs and radio possibly mp3 if connected, as these are built in to the amplifier which the speakers connect to.
If the tv has a Line out (via phono plugs) and NOT via headphone out, connect it to an audio input on the RCA surround system. If the RCA has no other available inputs, well....there ain't a lot you can do but watch CSI with the sound from the TV and then Star Wars (for example) through the TV and Surround system.
Best Of Luck

Compatibility fo TV and Sound system


TV has audio outputs, the RCA cable type. If you connect the audio output (red,white) from the TV(look on the back), and connect the RCA cable to Input of home theater system,you should get TV sound from home theater system. You may have to set the audio on the TV for external source. Go to menu, to audio setup, to options. On the Home Theater system, you may have to select the audio source, i.e. audio input 1, etc.

No sound though home theater when watching tv


There is an orange button on the remote, half way down in the middle. I belive it has orange lettering and says something like "TV-?" press that, and the sound should start to come through your speaker system. You can then use the original remote that came with your TV and turn the sound off on the TV to use just the theatre system. I noticed that if you use the TV speakers in conjunction with the theatre system, that it echo's.
