I agree with Mikey & OTT. It's probably just a popped diode that's now open circuit. Hopefully the rest of the board is fine.
I've replaced many components like this, usually with the luxury of tweezer soldering iron. However, without that I would either use fine solder wick (no wider than 2mm, preferably finer) and a fine point iron; or two fine point irons; or fine point iron and fine tweezers.
Not all SMD components are good candidates for solder wick as surface tension keeps solder under the leads, but with this relatively large diode, it might be OK. Use some flux on the wick from a flux pen.
Two fine point irons are the best bet. Heat both ends of the diode simultaneously and lift the diode away from the board.
If you only have one fine point iron, then by heating one end of the diode and carefully applying a little upward force with fine tweezers at that end you might be able to lift that end away from the pad. These diodes have wrap under type leads that will bend a little. Be careful not to apply too much force or you will tear the cold pad off the board.
You might also notice that there is a narrow gap under the diode. You could carefully place the point of a scalpel blade under the diode and apply a gentle twist as you melt the solder at one end of the diode.
All the best!
