I have an old pioneer DVD/surround sound system and a new smart tv. The Pioneer player is pre hdmi sockets so I have a choice of scart lead to converter box then hdmi lead from converter box to tv which I have tried with no success at all! Or use of the yellow component lead from optical output yellow socket point on DVD to tv. When I have done this I only manage to get a black and white picture! PLEASE HELP AND ADVISE ME AS I REALLY DON'T KNOW WHAT TO DO!!!!!!
