I can't be sure but it looks like there might be some bad solderings.
can you try and resolder the 4 pins needed
the trick is to heat both the pins and the "hole"
let the solder iron heat up till it's got the correct temp
then press the head into the corner between the pin and the pcb.. let all the solder melt and fall down, and it'll start looking like a vulcano.. then remove the tip again. this should take around 5 secs for the first one, and subsequently 2-3 secs for the other ones (pcb needs to be warmed up as well)
see if that helps you.
