My Sony model # MHC-V11 MAKES NO SOUND everything seems to operate but i cant get no sound from it

Troubleshoot this issue. Here are some steps you can follow:

Check Speaker Connections:
Ensure that the rear surround speakers are properly connected to the Audio/Video (A/V) receiver.
If applicable to your model, verify that the A/B speaker selector is set correctly. If the speakers are connected to the A speaker connection, the selector must be set to the A position.

Test Tone Operation:
Perform a test tone operation to check if the speakers are functioning correctly.
Increase the rear speaker volume or adjust the surround speaker settings to the maximum level.

Speaker Size Settings:
Try selecting a different size (small or large) for the rear surround speakers in the menu.
Surround Sound Mode:
Verify that the A/V receiver is set to a surround sound mode.
For Dolby ProLogic surround sound, ensure that the center-channel mode is set to NORMAL or WIDE.
If your source is a DVD or Blu-ray Disc player, check that surround sound is enabled in the player's menu.
The audio being received must be multi-channel.

Different Surround Sound Mode:
Try setting the A/V receiver to a different surround sound mode.
Source Content:
Verify that the source you are playing is encoded in surround sound.
Note that during periods of mainly dialog, most of the sound may come from the center speaker only, with audio coming out of the rear speakers when there is background or ambient noise.

Factory Reset:
Reset the unit back to factory default settings (consult your operating instructions for model-specific steps).
If applicable, follow the steps for calibrating the appropriate settings automatically after connecting the calibration microphone device.

Speaker Wires and Replacement:
Check and replace the speaker wires if necessary.
Consider connecting a different pair of speakers to see if the issue persists.
If you've tried these steps and the problem remains unresolved, I recommend seeking professional service.
