I was told to press button with satellite symbol at top of Topfield remote then use dvd remote. When I press satellite button, TV screen goes blue with a hache and 4 in top right. When I switch DVD on screen doesn't change. Any ideas?
That button is used when you have another device (like a DVD player) plugged into the bottom SCART socket on the Toppy; it allows that to pass through to the TV, so you can have two things connected when you only have one SCART on the TV, and doesn't actually control the DVD player itself.
