BOSE 321 DVD movie movie picure is blue. Its connected to a Sony LCD digital Wide screen TV Bravia Model KDL 40V2500 and my cable box. Could it be a loose connection.

I would Google the model number carefully for "problems" "no sound" and usually this set will display some kind of error code===it may even have a hard reset to try===service manuals are available on the net/web to allow you to see how the sound circuit is set up etc.

The cable u are using it is the S-video cable?Yes,this cable dosen't support audio.Must used a RCA component cable like R,W cable connected between the tv and the DVD player to get sound.

Try going into menu input set up on tv and switch to av input. Just a thought I have the same model and had exact problem. All I had to do was change input style to av cable.

Hi Dear. Thoroughly check and change function from TOOLs button.

Sir answer plzzzz

i had the same problem and the only way i could solve it was to disconnect power from the tv, let it "reset" then it would be ok for a bit. the problem went away entirely when the cable company updated its software for its hd box. might be coincidence....

also, pre-update, the resolution wouldnt automatically set correctly. If I turned on the tv to a hi def station, it would set to 480 and only set to 1080 when i changed to a normal station then back to the hd. then it was fine. again, after the update from the cable company this went away.

If you are using component cables to connect the DVD to the tv make sure you have the red,blue and green colors on your cables matching these colored jacks on the tv and DVD jacks. If one of these cables is plugged in wrong or not plugged in it could cause this. Good Luck

Do you have a cable or satellite box connected to the tv?

If you only have basic cable with no cable box this may be normal. You may need to upgrade your service or get a cable box.

make sure you have Tv on that particular HDMI input .I believe video 6 or 7 .if you do check menu make sure that input is not blocked. or you might want to try the component outputs of cable box and connect that to a component input on tv to see if that is working,,i have seen these tv HDMI input board bad..lets hoe this is not the case..
