I don't know if you solved your problem but I had a similar problem with my 590 remote. On the right side of the remote is a little switch that moves between the options Tuner/ Device/ TV. I hit every button on my remote, changed batteries etc to no avail, it drove me nuts until I finally noticed the little switch and it had moved to TV (probably sat on it or something). Could not believe I hadn't seen that switch before, but I never used it so... Anyway, hope you have solved your issue by now, maybe this will help someone else if so!
