Well, like most, I own an mp3 player, more specifically, a Venturer 512mb generic pile of junk. While one day listening to it, something weird happened, the head phone jack on it, cut out,however, i could still hear parts of the song, though heavily distorted, fumbling with it a bit, and it seemed that the contacts on either the headphone jacks were shot, or a solder had failed inside.
So i took it down to my local electronic repair shop (also known as my electronics teacher), and cracked it open. To my surprise, all of the solder holding the jack in, had failed. Problem solved?. After a quick resolder, it still does the same.
I was wondering, since there is no improvement after the repair, how could i go about diagnosing the problem further and repairing it?
