help?

I havent used my Panasonic PV-GS31 in a while, but i recently started using it again.
However, when i do film with it, I sometimes film with a fisheye wide angle, but the problems happens even without it so i know its not that certain lens.

an example of it is:

notice the blur on the left of me?
inside the pv-gs31's lens, theres what looks like a drop of water? but im not sure what to do to fix it?

any ideas?

If it's water, then it will evaporate eventually.
If it's oil form the mechanism, then you're stuck with it.
Probably needs to go in for a service, or replacement if it's too expensive to fix
Unless you're lucky and it's water and goes away of its own accord

its been like this all day, so i doubt its water.
where would i bring it for someone to fix it?
