I have had a Beovision Eclipse Mk 3 for 3 years and following some advice from MM have had no problems playing Masterlink sources on the Eclipse and Eclipse sources on Masterlink products. Have since added a Beosound Core which has also linked in well. The only unusual feature is that the Masterlink products show up as link products with the Core but don't show at all for the Eclipse. Though pressing Radio, on a Beo4, would play the radio on the Eclipse. That has now stopped. I cannot now play any Masterlink on either the Eclipse or the Core but can play Eclipse and Core sources on Masterlink products. Edit - forgot to say that the Masterlink source is switched on and controlled from the NL product and the source name can still be seen on the Eclipse screen, just no sound. Anyone know what has happened? Thanks in advance Paul   Beosystem 7000 -> Beolink/ML Converter -> NL/ML Converter -> into my NL products.
