    You could always find a nicer original board to repair, or find a refurbished one that someone has already repaired.

    Also try a WTB ad in the marketplace if you can't find something listed for sale.

    Rottendog has a combo board for the MPU & driver board, but it's a little on the pricey side.

    You need to neutralize the alkaline from the battery leakage, or it will continue to eat away at the copper.

    Vinegar isn't acidic enough to neutralize. Take a look here:


    Then sand down to the copper where the batter damage was, add your new components, and seal exposed copper with clear nail polish.

    Quoted from zacaj:

    Interesting! I've always been told to use apple cider or white vinegar, *after* sanding. Then again by the time I'm done sanding I don't think there's much left... A pain though

    With zep, it attacks the alkaline chemically, so I actually end up doing a bit less sanding since most of the alkaline is removed before getting to that point.

    Quoted from bronco-jon:

    Thanks, great thread! If I'm lucky I won't have to sent it off to get fixed. I don't have enough experience to do it myself.
    ...looks like those chips will clean up ok. do you think they will be alright? if not, where can I get some?

    Replace any parts that are hit with battery leakage with new parts. That leakage can spread like a virus and continue to corrode and damage the board if any of it is left behind.
