mp4 repair guide wanted

[chewy1991]

i bought a mp4 player about recently and the stupid thing stopped working, i have taken the srews out and looked inside and the black cable has come out of the main board. after trying to find the place that the black cable has come out of the red cable decided to come out aswell, i know where the red cable goes but i was wondering if anyone has a repair guide for my mp4 player

i dont know the exact model or make but i know that the main chip on it is a SAMSUNG K9K8G08U0A with PCB0 under it.

thanks in advance for any help available

p.s can anyone help me find the make and model of this mp4 player as that would probably help to find the repair manual
