Hi Friends, I have purchased Panasonic Plasma P42X30D few days back. On installation I found that after connecting TV's audio out to my Sony home theatre TV's sound is not coming through the home theatre. The engineer could not understand and shuffled all the wires. I even checked that in the sound set up it was set for TV and Home Theatre. But the only sound that's coming from home theatre is a light buzz sound. Has anybody faced a similar problem, is there some change that is to be made in the set up or is it the set that is defective.
