The RCA G27647 27" TV I'm having sound problems with (No sound,Video ok) will only fix itself if the tv is unplugged for 15 to 20 minutes. Only the coaxial input connection seems to be the affected area, as when I've used the Audio/Video jacks, the sound returns with no problem. Our local TV sales person is blaming it on "intermittent CATV signal levels that can't be fixed",but it doesn't affect our other RCA tv (different model) and the problem still occurs even after we have switched over to satellite. Has there been any similar problems with this model, and if so, any fixes?
I went in and checked the audio menu, and it is only set to stereo, so I still don't know the source of the sound loss when using only the coaxial input. There hasn't been any audio problems since I switched over to using the AV jacks, so short of putting in an AV switch to change between Satellite and DVD, I'm still kind of stuck. Any other areas I should try focusing on?I went in and checked the audio menu, and it is only set to stereo, so I still don't know the source of the sound loss when using only the coaxial input.

We have an RCA console TV. Periodically, the audio will stop working and we have to unplug the TV for a few minutes for the audio to "reset". We called a repair company and they told us it was due to signal changes in our CATV. We would like to get this fixed. Please helpWe have an RCA console TV.

Re: Loss of Sound
Go into your audio menu, and make sure it is not in the SAP(Second Audio Program). Very common problem when you get good audio on the inputs but not on the RF or tuner input. Good Luck

First, does TV sound without external sources work on both channels?
With the one RCA connected and getting sound, unplug it and plug into other channel. Any sound? If not, remove it and plug the other RCA by itself into the left channel. Sound? If yes, plug it into the right channel. No sound? If not, bad TV input.
If you do get sound on that other channel with a single RCA, then you have either a bad cable or bad source. Reverse RCA's on source and try same test, plugging each RCA into each input on TV one at a time.
If the TV is bad, you will get sound on just the left channel regardless of which RCA you use.
Tries tv and those pay boxes unplug,replug it back like about an hour later for the tv to do a resetting itself back to the factory setting.For those pay boxes to reboot and upgraded it softwares.Go into the tv menu go to Sound Setting go down do a resetting itself back to factory setting.By doing these steps tv have a great chance to get it audio back.If tv still have audio problems,than the main tv Tuner signal board have problems.Tv is under a year old.Call the Haier tv Corp.Take ur tv warrenty repair.
Unplug it for about an hour to let it reset itself, if it still does not work, you will have to do further troubleshooting. Let verify first to narrow down to where the problem can be. First, make sure the MUTE function is not activated, then check the on screen sound set up menu to make sure the speakers are not set to OFF. If the setting is OK, then attach the powered PC speakers to the Audio Line out RCA jacks (Red and White) to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit.

ok try unplugging tv then hold the power button in for 20 seconds then plug tv in and turn it on. Had a rca do this to me (tubed 32in) before I did this fix I ran audio out from vcr to an amp via rca cable audio out
Sounds like you have a tuner or an antenna problem. If you are using a DVT converter box to watch off the air TV, the signal has to be very good to get sound and picture. Try connecting a VCR or a DVD player trough the coax cable and see if it you get sound an pic on Channel 3 or 4. If you do, it is an antenna problem.
The beeping sound is most likely the high voltage generator needing replacement. This is a fairly easy job if you have some tech support to discharge the picture tube. You can go to the following link and leave them an email with your model number and your symptom and they will email you back with the part you need and they provide free tech support with instant messageing so you can do the repair yourself. the HV generator takes about a half hr to replace and takes only the basic soldering ability. heres the link. http://servicemanuals.vstore.ca/
You have a problem in the video circuit. Any video that comes into the set is not getting to the picture tube. The menus come from the system control microprocessor. This shows that the input at the picture tube itself is working. Also you system control is working.
The signal would have to be traced through the set to find out where the loss is originating.
