Out of warranty MBP ,Burned Magsafe port and frayed charger cable - repair option and cost?
The MagSafe board is a very easy repair for someone who has patience and a small amount of training fixing any computer at all. The MacBook Pro aren't as fidgety to repair as the iMac and MacBook Air (where I would say you should be a skilled technician with official training materials available to work on them reliably).



You're looking to replace this with a handful of screws turned.

Go to iFixit.com and look up the repair guide and parts list for the DC in board and you will know if you have the skills to find the right part, the right tools and the right manual to undertake this work. Otherwise, pay a local technician to do the job/source the parts/give you what they feel is a good guarantee. As for the adapter, buy a new or used one on the aftermarket or from Apple. When the cord is crushed and frayed, it is designed to fail in a way that won't cause a fire hazard. I wouldn't mess with that end of things or with repairing the transformer itself.
