monster high karaoke machine power cord ripped out.

[senjurio]

Kids accidentally ripped the cord out of karaoke machine, it was a permanently affixed cord. All that is left is the 3 prongs in the picture, which I don't understand because it says DC 12v 1.5 amp. I don't have the original cord, but I tried a DC 12v 1.5 amp power supply and couldn't get it to work. I'm thinking 2 are positive and one ground. Could anyone she'd some light on what is what here?

As good as I can get for now, I just noticed all that... what I'm assuming is oxide on the bottom.

I'm in davenn's boat about not being able to determine what you've got from the pictures you took.
It's POSSIBLE you've just got the +/- 12VDC 1.5A coming in from a wall adapter, and the big metal flap was a permanently attached strain relief from the power cord (that wasn't tough enough to do the job).
davenn meant we'd like to see the underside of the board head-on, so we can see where the electrical trace goes, not a sideways picture.
I know you don't want to pull the board out of the chassis, but it's probably necessary here so that we can see what's going on.
Can you do that?

The three larger ones are the three power prongs. Second picture is unedited.
