Hello, i've done extensive research into this problem and found many helpful responses, however Im still unsure with my particular problem. http://www.ifixit.com/Wiki/iPhone_Troubl... , Question 2 on that link shows my exact problem, however i've found that this jumper does not seem to have any physical damage. However, the slightly bigger jumper/conducter to the right they are called, is missing (directly above the second from the right ribbon connector). Could this cause the same problem? Or is it only the smaller jumper that can cause it? My local electronics store sells the circuitwriter pens so Im keen on trying to repair it, however Im just unsure on which of the two to try. Any reply would be greatly appreciated, cheers.
