Hi hope anyone can help. I have a Technics HD51 AMP, CD PLAYER AND TUNER AND CASSETTE mini hifi that are connected to each other with ribbon cables. It has been working fine and nothing has changed regarding wiring etc but what is now happening is when I turn the amp on, all the others go off. When I switch the amp off the CD and Cassette deck light up and it plays CDs with the amp display off but you can hear it. Very strange. Can anyone help? THANKS
