Hi! self also facing similar problem with AVR120. No sound coming from any channel. Video is coming from DVD but no sound. Display / Remote is working. Did a RESET but same situation. please advice next step. local repair shop suggesting that some 'IC for sound is gone and charging a bomb for replacement. Please advice.
The rear left and right channel has a audio output ic problem, first check rear speaker wires for shorts, if okay! the system will need to be assessed for repair costs.
Not familiar with your model, but the problem sounds generic. I am guessing your set is hooked to a cable tv box, and that is where you need to change channels. I also guess that when you changed channels on your TV you probably moved from channel 3 to either channel 2 or 4 and the cable tv box is not sending to those channels so you lose picture and sound. Now, more guessing, you try to put the channel back to 3 on your TV, but still nothing happens. OK, if close so far, there are a couple of things to try. First, be really sure you are actually going back to the same channel you started with. Assuming you don't actually have the signal coming in on an auxiliary line-in and that you had it coming in on a channel, you may need to reset the presets on the television so that it recognizes the one important channel the cable tv box is sending out -- just follow your television menu to select or set channels. There is one more possible easy problem ... I have seen this one happen, after getting the channel correct and reset, if it still doesn't work, you mght need to turn the set off and wait one minute, then turn it back on WHILE the cable box is ON. This can cause the set to RE-Latch onto the cable box signal. It really doesn't sound like something is truly broken or needs replacement, sounds more like a user error. If your set is still under warranty, just call the Panasonic hotline (find it in Google, and they may be able to walk you through exact instructions for your model). Hope this helps.
Try swapping your cables from the sound-bar to the TV. If the sound still only plays through one channel but the channel has changed from right to left or vice-versa, then you have a bad cable.
If the performance is the same, connect a different device using the same cables to see if it's the sound bar input or the TV output.
Once you know where the problem is (the sound bar, the TV, or the cables) you'll know what unit needs repair or replacement.
It is entirely possible that a solder joint for the sound-bar has come loose. A soldering pen would easilly fix this if it's a bad joint/connection.
You may have to do some testing...if it is coming from the belts, start disconnecting them, don't drive the car since you will loose the power steering, but see if the noise still exists. Then if it does, is it coming from around the timing belt area, which brings me to my next question, has the timing belt been changed? Even if it isn't the area of noise; it needs to be done, and the water pump has to be replaced at the same time...location of the grinding noise is important in order to diagnose properly.
I hv philips 21RF vardaan TV ,there is sound on AV channel. and the picture is blinking. even some menu setting have changed.. i tried using the service menu but cudnt understand anything. 2 new av channels have come.. av2 and front which were not present before. sound is not coming even on the other channels but picture is fine on them. only on the av1 channel it is blinking., the philips technision had solved this prob once by pressing some code by remote and i don't know the system code
Did you hit the "input" or "video source" button by mistake on the remote or TV? That would change the input from the one the cable/video source uses. You're getting sound, so it's working......sounds as if the input was maybe changed. I'd hit the input/video source button a few times to go through all the available inputs and see if you get video back.
it is highly likely that you're TV is outputting mono sound, hence the left channel only. check your physical connections to the TV and the balance / channel volume on the television as well.
