Looking for an installation manual for a Dual CD770

Should be a 3.5mm audio jack or AUX on the front some radios use an additional left right input on the back , if there is a 3.5 in on the front just use a male to male 3.5 cable if the input is in the back use a 3.5 male to phono male(2) adapter , usually red and white

it would be cheaper to replace the unit

it would be possible with the right tools and knowledge and a replacement screen but it would be cheaper to replace the unit

Change the Flex cable that connects from main chassis to the front face plate. This is a common problem with Dual drop down face plates, since the flexible wires break and lose connection.

No mine did that and what it is is there is a strip connecting the two faces and sometimes it gets stuck and u have to gently pull it out and it fixes the problem worked on mine

my pyle cd player comes on but wont play any sound
