I have no power.

@patience the only way to accomplish that is by soldering a new connector to the board. It is a bit tricky since the connector is an SMD part. It is soldered on top of the board and it does require some good skills, but it is doable. Check this video for more insight. You can get the part from places like this ans many others. If you are not sure about your skills of getting it done, you might just want to try a TV repair shop and see if they can do it for you. Make sure that the cost for the part and the repair do not exceed that cost for a new logic board, so I would think no more than $60 together.
