Well after a few years it looks like my Harmony 880 is experiencing the 'volume up' button failure. Has anyone seen this problem and taken theirs apart to fix? Worse case I will remap it to another button. I can't afford a Harmony One at the moment.
Fortunately there is the up and down arrows in the middle of the 880 that you can remap it to, temporarily.
Here are some other people having some of the many problems with harmony remotes: Search "volume" on the page.

After reading the post on Oct 12, 2009, I'm not sure I am buying another Harmony remote again, at this point.
Edit again:
Look at post #5728 here:

Apparently if you call harmony they'll give you a 50% coupon of some sort to by a new one from their site.
