(1)Reset your tv from setup menu then auto tune analogu chanel.
(2)if still no sound then update your tv softwear from sony site.
(3)If still sound not then need to replaced main board problem.
Usually this happens to my set when I am in HD cable channel mode after being on a non-digital ANALOG channel.
I basically reset the TV by changing to a DIGITAL cable channel -- stay on that channel for ten-twenty seconds -- then I switch back DIRECTLY to a HD channel (key in channel number directly on remote).
TV works fine -- seems to be a glitch when the TV changes modes from Analog to HD
Hi my name is Roety,
I can help you with your issue ,
Without a model number, I do work on sony LCDs.
The audio is on the mainboard. You need the mainboard replaced.
Reboot every device by unplugging the AC power , if the sound still cuts off replace the mainboard

Make sure video cable is connected on right socket. for instance AV1. test cable box on other tv to see if it is transmiiiting picture. If so make sure your tv is tuned to cable box if using RF cable or on slected av mode where av cable is connected
Had the same problem with mine.
Took off HDMI cable and used the HD cable (Red Blue and Green) for video and standard (red and white) cable for audio.
Problem gone
This problem appears to be an issue with numerous Sony Bravia owners of the same model. Although still seeking a soulution, it would appear that our cable provider (Verizon) has replaced all of their components and the Geek Squad from Best Buy where we purchased the unit, points the finger at Verizon. None of our other Fios-equipped TV's exhibit this problem so I am glad we bought the service plan with the TV and will continue to seek a remedy.
