Lens barrel on Hasselblad 50mm has come loose

Folks,
During a 2 month trip through Thailand the lens barrel of my 50mm lens came loose. The lens itself is fine but I have to hold the camera with one hand and hold the barrel in place with the other hand. I am guessing that normally it is held in place with a couple of screws. I am guessing that there is a way to remove the front element of the lens to get to those screws. Can anyone point me to a place where I can learn how to repair my lens? If not any reputable places to send it for repair?
I have posted a link to the YouTube video to further illustrate what's going on.

Thank you,
