When watching a dvd on our sony tv we have sound problems

Do you have the DVD connected to a surround sound?

Hi,
Check TV Speaker option in setup/ option of Menu and make sure tv speakers are ON to get sound in tv speakers.
Thanks.

Make and model of the cable box?

it could be the signal strength for your cable isn't strong enough. alot of people are encoutering similar problems ever since the digital switch over

You can get a replacement U board at the following link which is most likely the problem as the U board has all the input sources on it. Look under the Sony parts category for the U board. They have the one for your model

you are using the svhs scart if it has another scart swap the plug over

audio out from your tv to your reciever gives low output? how do you have everything hooked up i have vcr to tv dvd to vcr audio to my reciever and vcr tv thru piggy back plugs therefore i can only have tv audio or reciever or both

The problem i had was when i would play my tv. I had it hooked from my dish to the sony then the tv. When i played a dvd,cd or the tuner it didn't make that noise. It seems my video/audio 2 channel was going bad. I disconnected my rca jacks and used the optical audio connection. The noise stopped and i got a better quality sound.

hope this helps

If you can not turn on TV set with the power button on the TV its not a standby problem as this would by pass the standby. Theres most likly, on a set of this age, top have a poiwer regulator problem and is going to need a trained tech to assist you in this repair.
