The Power button on the remote stopped working, but all other buttons seem to work. WTH!
If used to much buttons can lose conductivity, it paint flakes off and the key no longer works.
I too have buttons that ceased to function. In my case, I was trying to remedy a problem and I screwed up. However, my “cure” was to reprogram the remote and now everything is working fine again.

I had $150 URC mx-650 universal remote whose keys started to fail after 3 months. It happens.
