Just wondered whether anyone could help me get my head round things. I bought a SIM Domino with Pioneer VSX - AX2AV AV amp a few years ago I originally had a SKY Box - the output signal went to a splitter. One went to the TV the other went to another splitter that outputed the signal into RGB. The RGB then went into the back of the AV amp into input 1. The output then went as RGB to the Domino. You then had to go through the input instructions on the amp and tell the amp that the sat signal was RGB into the rear input 1 . All worked fine When the Domino is on you choose the screen input and I have it on RGB auto synch. I can't seem to get a screen at all nor sound as well. The only thing I've changed a few years ago was replacing the Skybox with a Sky +HD. Is this the problem as I have a VGA cable directly into the domino and that works fine. Also I have a separate HMDI cable but I can't get my Panasonic blu rayDMP BD80 to work direct to the Domino. Wondered whether that could go through the amp. Is it the amp that is too old now and I need to replace that ?
