We lose audio on our Sony BRAVIA KDL-52W4100

For no apparent reason, we lose audio while watching the TV. To get it back, we have to change the channel and then go back to the one we were. It happens at random, no comun factors for this occurrance.

    I have the same problem. Sony support asked me to update my s/w (which I did not even know I could do) via a flash drive they had me update s/w right onto the back of the TV -
    now for the bad news, this did not work - I'm still trying to fix the problem. I just read today a posting on another troubleshooting website to try this ::"you have to bring up the menu on the cable box that allows you to select HDMI as the audio source. I actually found the solution on the Internet, and not from the cable company."

    same problem, it happens about 20 times a day. TimeWarner has checked my cable connections, hardware, etc and changed my cable box 3 times. TV works fine with Wii and DVD, just with the Cable box, which leads me to believe that there's a compatibility issue with the Bravia Sony TV's and the cable boxes available out there.



    Can someone explain to me in step-by-step instructions how to choose the HDMI setting on the cable box? I have an Emerson cable box.

    thank you

We have the Sony Bravia KDL-55EX500. We have intermittant sound outages daily. Cable company has been here eight times in last year. Have changed HDMI cables twice at suggestion of Sony, as well as updated software to latest version. We have changed the cable box three times. Sony blames cable company. Cable Company says Sony Bravia has a defect. They even showed me their Bravia in the cable company offices and said it cuts sound where all other sets dont. This is a Sony defect and they are deflecting. Do not buy a Bravia as Sony will not admit defect.

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.

Scratches on Sony Bravia kdl-52w4100 screen cause white specs that never go away. Can this be fixed?


If the screen is scratched it will need to be replaced, so yes it can be fixed but it will be expensive. If you have nothing to lose you could try reducing the effect of the scratches by polishing across them gently with fine jewellers rouge, try a corner first as it might completely ruin the screen. Not too much pressure as you will damage screen further

KDL-52w4100 won't turn on and LED blinks 6 times


Bus clock and/or data lines low at power on. 6 blinks of standby light denotes this. Actually, it should be a motherboard problem. Your TV need a thorough checkup before confirmation. If you wish to get more details about the blinking codes to Sony TVs, check this link.

I have a Bravia KDL-52W4100 and the screen is starting to flicker when watching TV or DVD's, but not when I am in one of the Menu's.


I have seen about a dozen questions here in the last ten days with several models with the same type of problem, Sony of course says they are not aware of this issue---typical for them to deny until smoke turns to fire.....
