One rather dangerous way to look is to set some music going and try the phono bin on likely looking connections. Whem you hear the music through the channel, you know the connection..
Best practise is to use an oscilloscope to check which pinv have a wobbly analogue music wave on them.
What's almost certainly happened is board traces have been damaged from the connector being dragged around.
