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?

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

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.
there is no internal switch inside the tv to fix the problem. have you unplug the tv for 5 minute and see if it reset. if that don't work is in internal circuit sound board unit, sound is a bit difficult to diagnose and fix yourself, Any tv shop can fix the issue under 100 buck replacing the board, or you can bypass the sound by using RCA out put from tv than to an amp OR spend 50.00 and get a computer speakers that has an amprefier built into it and plug it in head phone from your tv and you can control the volume from computer speaker unit. My friend has the almost the same issue that the tv wont change channel by remote or from tv unit itself, so we use cable box and the remote to by pass the problem. I hope that help a bit..good luck!
I have a GE 46 in TV that had the same occurrence. I believe it is a sign that the amplifier is overheated or stressed. The way I fixed mine was to unplug TV and leave off for a few minutes -then plug in. I discovered this by accident when the power went off one day and the sound returned (had been using my vcr audio output plugged into my stereo for weeks!) This fix will work for weeks-sometimes months-evidently resets the circuits inside the amp somehow. Last time this happened I also removed the back of TV and blew out the dust with compressed air while it was unplugged-still have sound 4 months later without a "reset"-so I'm guessing it did help .
hpesoj the problem comes from the satellite in the sky, too many bits of data for your chassis, only fix involves adding a capacitor to the microprocessor, note that if the modification is done your closed captioning will no longer work, but it`s the only thing that will stop it other than un-plugging the ac cord waiting for a short time and then re-apply the cord, which you have already found out, any local tv tech should be aware of this "so called fix" give them a call, good luck, BMW Rider
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.
