My sound system previously worked well with my Panasonic 42" TV, however, the tv gave up so a new tv was bought. The problem I now have is that the sound system does not have an HMDI adaptor. The tv and sky HD box works off an HDMI and the sound system is connected by scart lead. The major problem that I now have is that the voice and vision are out of of sync with each other. Can you give a solution to the problem so that we can still use the panasonic sound system with the new tv and sky hd box?
