@sangntp before throwing it out, can you clean that are with some isopropyl alcohol and a soft brush? Then repost another image. I essential agree with arbaman but would like to see a bit more.


@oldturkey03 can I use gasoline?


@sangntp I would not because that may just destroy your board.

There's not much you can do yourself probably, it's a bad short between one of the main resistors and a mosfet, probably part of charging and/or main power line, the one carrying 12,5v around the board. I'm afraid the damage is not limited to those burnt components.

You need to change your logic board or find someone in your area specialized in component level repairs who can fix it, but it won't be cheap. Charger should be fixed or replaced too.

There's no other alternative as far as I know.
