No Audio How can i reset the audio

Check all connections from the DVD player to your amplifier/receiver and TV. Make sure the audio cables are securely connected at both ends.
Try connecting the DVD player to another amplifier/audio system using different cables to isolate if the issue is with the player or cables.
Check the audio settings on the DVD player - make sure audio output is enabled and set to an appropriate format like PCM or Bitstream. Go through the audio setup menu and reset to factory defaults.
Make sure the volume on the DVD player is turned up and not muted/very low. Try different audio tracks on a DVD movie to test.
If connected digitally via HDMI, try swapping to analog RCA connections instead. Or vice versa.
Try playing audio CDs to see if the issue only affects DVD movies or all audio.
Make sure the audio on the disks themselves are okay by testing in another player.
If there was a power surge or electrical issue, the audio circuits could have been damaged. A repair service may be needed.
As a last resort, perform a factory reset or firmware update on the DVD player.

4 - Push the odometer reset button once and you will see the selection menu "PSSPt" with the first P flashing.
5 - Each letter represents an area of the diagnostics module. The module that is flashing is the one you are going to check. To move from one letter (module) to the next, you push the odometer reset button one time. (from P to S to SP to t and back to P, etc.)
P = ECM/ICM (Electronic Control Module [EFI] / Ignition Control Module [Carbureted])
S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)
SP = speedometer
T = tachometer
6 - To get the DTC within an area of diagnostics, push and hold the odometer reset button in for 5 seconds and release. If there are any DTC's the code will be displayed or the word "none" will appear if there are no DTC's. Push the odometer reset button again to view additional codes if they exist.

If the + and - bottons don't work, maybe there's an issue with the audio processing stage, please try resetting audio to factory settings, go to audio menu and select reset option, if this doesn't work, your TV could need the audio stage to be repaired.

Click on the link below to view the BOSS audio BV9560b user manual, inside the manual it will show you where the reset button is located:

http://www.retrevo.com/support/Boss-Audio-BV9560B-Car-Videos-manual/id/23353ci554/t/2/

reset yourdenon AVR1084, see manual

Unplug,replug about an hour later let the tv reset it self.Go to ur tv menu.Go to AUDIO go down to reset.The audio should reset back to factory setting.Ur sound should return to normal.

Unplug,replug the tv about an hour later let the reset itself.Go to the tv menu,go to AUDIO go down,than reset the tv audio.The audio now should return,not than the Tuner board is dead,must replaced the Tuner board to solved audio problems.

I would reset the factory defaults on the TV, but some complicating information follows these instructions:
Reset Factory Defaults
To reset all settings and channels to their factory
default values:
1 Press Y and open the Setup menu.
2 Highlight Installation and press T. A new set of
Installation menu icons will appear.
3 Open the System Status menu, highlight System
Information, and press T.
4 Press C c to scroll through the menu bar to select
Factory Defaults.
5 Enter your PIN code (or 0000 if no PIN code has been set).

Because the PC and HDMI-1 inputs share the same set of analog audio inputs, the PC Audio menu setting influences the HDMI 1 Audio menu setting. If PC Audio is set to “No,” the HDMI 1 Audio setting changes to “Auto.” If PC Audio is set to “Yes,” the HDMI 1 Audio setting is set to “Digital” and is grayed out in the menu. (Also see item 5 on page 12 of manual and “Setting the HDMI™ Audio mode” on page 43 of manual).

There is also some good information on pp.20-22 and 54-57 of the manual - this one has a lot of audio hookups and settings.
