This morning I noticed one of our roku boxes blinking away, so I powered it off and on and got a steady green light from the box unit. I then turned on the TV and tried to use the remote and nothing happened. I assumed it was remote battery issue so I replaced the AA batteries but it still didn't work. I went on the website and followed the troubleshooting steps -- including the re-pairing but the remote still isn't responding to any push button commands including turning tv on or off. Right now we can't use this TV for streaming until we get this resolved. Please advise.
