Menu > Setup > Melody.
Additional information would also be found on page 22 of the user's manual (US). For other regions, it would be under "basic features".
Does that help?
I have seen references to this on the forum before, although the solutions dont fit with the menu on the plasma television I purchased a couple of days ago.
The Model is a P550C450B1WXXC and Type PS50C450.
Could you please confirm the sequence for this model to turn off the music at swith on and off.
Many thanks in advance.
