haven't seen that happen yet on these boards... I think soldering in a new SMD led shouldn't be to tough, especially if it's just one color.
you just need to be really, really careful with it. If I was you I would seek out a replacement board though, can't imagine those kiss boards are going to be around forever.

I'm not a fan of SMD for lighting, but it is what it is.

also if you can get the part through your distro, it's usually cheaper then going through an online retailer.
especially on stuff like this... sometimes.
