I have a cable controller connected to a Bose sound system and a Haier 32 " flat screen TV. Everything works great until I want to view a DVD, then all I can hear is cable audio with the DVD video. How do I get the TV audio to the Bose sound system from the TV.

If there's no sound at all, switching channels or not, then you may want to check this out:

The problem turned out to be the TV itself. Somehow all the a/v and component cable inputs on the back of the TV got disabled. After finding then consulting the TV manual online (the TV is about 8 years old), we found there was a way to reset the TV to its original factory settings. Voila, the a/v and component cable inputs were enabled again, and everything worked correctly afterwards.

I have a question? Do you move your Television frequently, OR do you unplug it frequently when it's not in use? I have found that doing either or both of those things can bring on problems, especially audio problems.

I've had the disappearing sound problem twice with my Element FLX-2610. This latest time I was stumped because the full scan didn't resolve the problem. And of course, the sparse manual that comes with the TV contains no troubleshooting advice at all.

But I did find a suggestion on another sveral other sites: Reset the TV. You might have a small reset button (like you would find on a DSL modem) somewhere on your TV but there is a manual way to do it two. Whichever way you do, MAKE SURE to disconnect every single device (yep, it's a pain) and UNPLUG the TV before doing this.

To reset with a reset button, disconnect devices and unplug the TV. Depress the reset button for 5 seconds. Reconnect devices, then plug in the TV.

Manual Procedure:
Disconnect all devices
Unplug the Television
Using the on/off button on the Television (NOT on the remote), depress and hold the button for 5 seconds.
Reconnect the devices, then plug in the TV.

Unless something has shorted out or burned up inside, this resetting, as a last resort, should fix the audio problem. Worked like a charm for me!

Good Luck!

Did you select TV input on your AV38 Bose system and same thing for VCR. it should work unless from your TV audio if you watching HD signals some of the program had copy protection so it turn off the video and audio out at your TV output monitor that for TV
For VCR it must work make sure you select VCR input on your AV38
