I have a JVC model AV-27050. Lately, for most of the channels we watch we have to turn the volume up to max (50) to hear the dialogue. You can hear the hiss of the speakers as you would expect at such a high volume setting, but the dialogue is too soft otherwise. We've checked every setting we could find with no luck. It is like having external PC speakers turned up to max when you have the software volume setting set to minimum.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Unless you are lucky enough to be close to one of the remaining low-power analog stations, you will need additional hardware to watch over-the-air programming with the AV-20220. You will need a digital to analog converter box. Connect the antenna to the converter box and then connect either the antenna output or the composite output to the appropriate input on the TV. If you use the RF input, set the TV to channel 3 or 4 and set the converter box to the same one.
Then to set the TV up to scan for any NTSC (analog) stations, you need to access the menu. There is a menu button on the remote. (I'm not sure about the AV-20220. Some of the later models (AV-27350) have a menu button on the TV as well.) Press Menu several times until you see Initial Setup (Setup). Use the up and down arrows (Volume) to navigate to Auto-Tuner Setup. Then use left and right arrows to choose Air. Use the up/down arrows to navigate to Start. Then press either the left or right button to start the scan for channels. Wait for the scan to end.
The tv programming codes that was came with ur owner manual belong to ur tv model don't work.Useally u out of luck.Try website like Remotes.com to buy an original remote or very close to the original remote.Also might have some more programming codes u can tries.
So the speakers and the individual amp channels work so that lets out the obvious big hardware items.
This is starting to sound like an obscure setting was set or changed by mistake.
It would be nice to figure out what that is/was in case it happens again but you may eventually have to resort to resetting the receiver to factory defaults and start over by holding the1/0 button for 5 seconds.
between image controls, (contrast-brightness-colour), Check the "colour" setting. should be near the middle of it's way.
if an automatic scan was performed before the event, please start it again, but assure proper country selection when asked (or better, check if there is a country selection menu and have it set to your country BEFORE starting the autoscan.
Well, some TV stations do broadcast at different volume levels. This is very noticeable when watching a TV show and the volume seems normal and then when a commercial comes on, the volume is very loud. They do this to get you to pay attention to the commercial. Another problem might be that you are adjusting volume from both your TV and your cable box. What you should do is make sure your cable box is set to "FIXED VOLUME" and then just adjust your TV volume. Fixed volume will have the cable box output only one volume level, letting the TV do the adjustment. Just go through your cable box setting and look in the audio settings. Hope This helps...
Powering off usually points to issues with speaker setup. You should read pages 42 and 96 of the 606 manual.
Page 42 covers impedence settings. Check your impedence settings for your speakers. The 606 handles speakers from 4 to 16 ohms. There are two impedence settings on the 606 - 4 ohms and 6 ohms. Set to 4 ohms if your speakers are 4 ohms or more but less than 6 ohms. Set to 6 ohms if your speakers sit between 6 and 16 ohms. Incorrect settings can result in the 606 going into power protection after prolonged use or at higher volume.
Page 96 covers testing for unexpected power protection. You should switch off your AV at source and leave for an hour. Disconnect all cables to speakers and other peripherals (TV, DVD et al). After an hour turn on AV and turn volume to MAX, If the AV remains on, turn down volume to min, switch off AV and reconnect all devices. Make sure the speaker cables are properly connected and that no bare wiring is exposed.
Once you have done this switch on the AV and turn to volume to MAX. If the AV stays on then problem solved. If the AV switches off then you should contact your supplier.
Does the screen go black with the volume still working ? If so check to make sure your closed caption is turned off . If the sound turns off as well like the tv is turning off , then it might be going into shutdown. Some of these sets have had bad caps in the startup circuit . Let me know , Good luck
I've never really heard of the audio being locked in these units.. I do know there is a back-door code to unlock the channels, just press 8-8-8-8 for that...
It is possible that the auio amp is out, in this unit it's a TB1253an and a simple repair for a shop...
Hope this helps!
