Turned on the 5D this morning and found that the Down Arrow key appeared to be stuck. Moving the cursor via arrow keys is impossible, clicking to a new area, the cursor immediately scrolls all the way back down to the bottom. Not something I can just "deal with" when we have a big festival coming up in a few days. Just left a message with Yamaha support, and tried reinitializing the board but to no avail.
I'm going to open it up right now to see if it's a hardware issue with the key being physically stuck, but it doesn't feel like it. Worked fine yesterday, been sitting with the cover on in the ~70 degree (florida) shop overnight, can't see why it would suddenly go bad like this.
Wondering if anyone's experienced this before?
