I had similar problems when I first got my Skateball (now sold) after it travelled to me and it ended up needing a few chips (removable ones).

Let us know where you live and then maybe a tech from here can visit you if they are close or alternatively if you are not confident to identify the issues yourself you can always take the board out and send to a member as a few techs that can help. Make sure to tag the leads and take photos before removing if you are not confident.
