I have a house full of wooden Hunter Douglas blinds. One of them is
broken. The cords that are used to change the tilt of the blinds
don't work. I've tried taking the blind apart but can't figure out
the mechanism, the problem seems to be inside a little box that the
cords come out of. I was unable to get that little box open.

Unfortunately, we can't seem to find anyone who is willing to repair
it for us. I misplaced the name and phone number of the guy who sold
us the blinds 2 years ago, and nobody wants to repair a blind
installed by someone else.

I suppose we could just replace that blind set.

Any suggestions?

Thanks in advance.
