Hi! Please excuse my limited knowledge and a simplicity of my explaining, but I'd really like to get some answers as couldn't find an appropriate one.
While cleaning the lifted pad area with a needle (I know I know), some of the brown (?) surface was scratched and a small dot-like copper surface was exposed. I made a new pad using a tinned cop wire and glued it with epoxy. I tried to solder the smd detail into its place, but it seems that the device (an mp3 player) still isn't working. So I have these following questions:
1) Could that exposed copper be at fault?
2) If so, how to fix it?
(The attached pic isn't mine, just to add some visual).
Thank you.
