Hello, I am trying to repair a DC Power jack on a toshiba satellite 2435. The computer will not take a charge at all even from a new power cord. If you wiggle the cord enough my sister says the charge light comes on very briefly once in awhile. I have not seen this happen. I do notice that the large center pin in the center of the DC Jack is slightly loose and wiggles back and forth. Possible from the cord being tripped over? I would assume that the pin should be solid and stationary in he Jack. I have already disassembled the laptop down to having the motherboard on my desk with full access to the DC Jack. What I would like to ask is whether the solder joints look OK. My soldering skills are amateur at best. All the solder joints for the DC Jack are yellowish/brown. I'm not sure if this is ok? Posted is a picture. I'd appreciate any feedback i can get as to whether the whole jack should be replaced, just resolder some joints, or anything else you can tell me. Also, anyone know a really good soldering tutorial online. Thanks alot in advance for the help.
