Answer to "when I turn music onto shuffle songs same song keeps repeating"When you are viewing the song, at the top right just below the total song length is where the shuffle icon appears. It shows in blue when shuffle is active and white when it is not. On the top left, just below the current time for the song is an icon with two arrows "chasing" each other. They are white when repeat is inactive, blue when repeat full playlist is active and blue with a tiny number "1" when repeat 1 song is active. I suspect that you have the repeat 1 song option set. Tap that icon once more to turn it off. Then shuffle should work as expected. Hope that helps.
Answer to "still does not power on after logic board replacement"Sorry if this may seem obvious, but I thought I would toss it out there. Have you tried resetting the SMC? http://support.apple.com/kb/ht3964
Answer to "DC in board testing?"I have the same question. Does anyone know the voltage readouts for the DC In board connector that leads to the motherboard? I want to verify that the board is putting out enough voltage and would rather not replace it if the problem is with the motherboard.
