Solved! Help in headphone jack replacement

[imeldacelajes]

I am confused about where the colors should go. I currently have a philips tx1 and the colors that I found were red, copper, red-copper, and green. What do they mean? I think red is left and green is right but i am very confused with red-copper and copper. Please I need help ASAP!

You could look for continuity with an ohm meter. See if the red/copper and copper are the ground side of each headphone side.
