I see some models shipped April 2016 so is it in warranty?
Try new batteries and why are there more than one remote? Is there some problem with remotes that had you buy more?
We have a Samsung 6300 tv and it recently stopped responding to power on/off signals from any of our remotes. The volume and other buttons still work, just not the power.
Any suggestions on what to check or do besides using the jog stick? Walk 10 feet to the tv?!?! The horror!!!!!!
