Got one of these beasts off Andy of Weston on appro so to speak having difficulty getting it to work !

Peter has very kindly been of assistance in verifying the power pack is the correct one.

However the pic on the case indicates the +ve supply line is the centre of the socket and the outer sheath is negative - the power pack has been setup in this manner but the piece don't work, have opened up the box and the socket on the board appears to take the +ve feed onto the -ve  side of the first decoupling electrolytic cap this cannot be correct tried the supply the other way round still don't work !

Suggestions gratefully taken onboard!

Come on guys/gals help please!

I used to use one and I do remember having to reverse the polarity of the power adapter to get it to work! What is your TV? What do you connect at the back of the expander. p.

Got an mx7000, also a 4000,ie  the current beast - use av2 connection - but without it connected to anything would assume the on / off led would light or does it need to be in service so to speak with a signal from the tv?

Have also replaced the on board 15v zener to no avail
