Ordered a new main board and got it within 1 day which allowed me to replace the old one over the weekend. Took not even 30 minutes get it done. Part came with great instructions and works as far as I can tell so far.
The work itself consists of locating the main board, unscrewing the nuts holding the cover in place and then unplugging the old board and plug the new one in. To make sure I don't miss anything I numbered the plugs and sockets, drew a rough sketch of the location of each on a piece of paper while also writing the number on the corresponding plug.
Needless to say, I will order here again.
