Question about RCA P46924 46" Rear Projection Television

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????

Re: Static audio on certain channels

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.

Projection TV. DVD works. Cable often seems, "untuned". Static & un-fine-tuned sound of channel with black screen. Then, later, it will come on just fine. Sometimes, will go back to untuned status.

I would suspect your cable box first. I would unplug the power cable from your cable box and wait 60 seconds. Plug it back in and try to watch cable tv. I would also make sure the coaxial cable going from the wall to your cable box is connected properly. I would also make sure the cable going from the cable box to the tv is connected properly. Test your tv and see if it works correctly when you watch cable. If this fixes the issue you are good to go.
  • If this makes no difference use a set of new cables if you have them.
  • If this does not work then call your cable company. They may have to replace your cable box.

Can you hear any audio? Look behind the TV, you should see some light emitted from a grill back there. If you hear audio and it appears you can change channels and what not, you lost at the very least your back light, which can be replaced , or worse the power supply to the back light which will cost you a bit more than the already expensive backlight.

No audio...only static

This is caused by a corrupted signal being sent out by one of the stations you are watching. There is definitely NO PERMANENT SOLUTION to this problem. Just keep unplugging the TV.

Poor sound cqality on a Samsung DLP TV

If you are receving your HD via a cablebox, check the volume and audio settings in the box's menu. Some boxes have internal volume controls. If the level coming out of the box is below a certain level, you may experience low or poor sound quality. You can also check the audio settings to assure that they are set to the original settings.

Channel skipping in Sony Rear projection KP-EF41 TV

is the channel flipping always happening at set intervals? Or, just randomly? Try replacing the batteries in the remote. If that doesn't work, start looking for other sources of IR(infrared). In some rare cases, direct sunlight on the TV will get it to do strange things.
