Hank Sullivan :

Hello my name is Hank,

Welcome to Just Answer!
I can help you with your Sony TV

Hank Sullivan :

Are you using a cable or satellite box?

JACUSTOMER-73wzef4o- :

Thanks my husband knows more about the tv and he is in the bedroom hold on....

Hank Sullivan :

ok

JACUSTOMER-73wzef4o- :

it is a cable box

Hank Sullivan :

is it always the same channels that have no sound? how long has this been happening? do those same channels have sound on any other sets in the house?

JACUSTOMER-73wzef4o- :

it just happened about 30 minutes for the first time. My tv in another room is not having problems

Hank Sullivan :

what is your connection type? Are you using an HDMI cable from the box to the TV?

JACUSTOMER-73wzef4o- :

we have an HDMI cable.

Hank Sullivan :

ah, I see. there may be a firmware update that can resolve this issue, hang on while I retrieve your documentation. . I'll be right with you. . .

Hank Sullivan :

which number of HDMI input are you using for cable 1,2,3, or 4?

JACUSTOMER-73wzef4o- :

we dont know

JACUSTOMER-73wzef4o- :

we have had the tv for probably 3 years. no problem till now

Hank Sullivan :

when you first turn on the tv, it will display the input name in the top left corner (example: HDMI 3)

Hank Sullivan :

this is quite common with HDMI connections, audio issues, intermittent audio etc

JACUSTOMER-73wzef4o- :

he is going to try. We had unplugged it so it will take a few minutes

Hank Sullivan :

ok

Hank Sullivan :

unplugging it may resolve the issue temporarily

Hank Sullivan :

you may want to remove the HDMI cable from the back of the tv and insert it into a different HDMI port

JACUSTOMER-73wzef4o- :

HDMI3

Hank Sullivan :

Sony does have a firmware update that mentions a fix for some audio issues

JACUSTOMER-73wzef4o- :

we also have a dog that may have stepped on the remote

Hank Sullivan :

it's unlikely that the remote would have an effect on some channels and not others

Hank Sullivan :

I can link the Sony page that has the download for firmware. . hang on. .

Hank Sullivan :

here is the Sony firmware update page http://esupport.sony.com/US/perl/swu-list.pl?mdl=KDL37XBR6 if you have a USB flash drive, then you can download the file, follow the instructions for unzipping the files, then install the USB into a USB service port on the tv to load the firmware

JACUSTOMER-73wzef4o- :

it seems when my husband turned it back on it started to work again

Hank Sullivan :

yes, that makes sense

Hank Sullivan :

it will work again maybe for quite a while, maybe for only a short time

Hank Sullivan :

you can wait until it happens again, then go to the sony page and get the new firmware

Hank Sullivan :

next time, just turning off and turning back on either the cable box or the tv may restore the audio

Hank Sullivan :

If you continue to have audio issues that begin to become aggravating, you can choose to switch your cable box wires from an HDMI to a Component cable and that will also resolve the issue in a permanent fashion

Hank Sullivan :

also, it's never a bad idea to give the cable box a reset, they do need to be reset at times and it can help resolve certain issues
