I don't have board view/schematic documents for this particular board, but it is easy to figure out which component is missing;
1. Google your board number followed by schematic/boardview. For example "820-2577-A schematic".
2. Once you have downloaded both documents, use the board view document (with a board view program) to locate the component. Click it, and it will give you the name.
3. Go to the schematic and search for the name of the component. It will give you the value of it, so you can find it on Farnell/Mouser/Digikey. If it says "no stuff", it means there is not supposed to be a component there.
You will then need to solder the new component on. Also, the component above it will need to be seated flat to the board, since you knocked this as well.
@oldturkey03 Didn't know that, that's not good :(
@fogsvans Best solution would be to buy a non-functioning model of the same year and swap the components, unless you can find a dead board on Aliexpress/Alibaba?
