How to repair the LCD connector path of an iMac?

@julionieto start off by giving us your complete model number so we can properly identify what computer you have. then you want to see if you can find the 820-XXXX number on the logicboard. For what you have in mind you will most likely need the schematic and the boardview for the logicboard. Also, post some good images of your logic board and where and how the adapter has failed. that will allow us to see what you see. Use this guide for that. If by contacts you are referring to the solder pads, you will have to try and run wire jumpers to the next valid point. Not always a successful repair but we need to see more so we can give you proper answers.
