1. Fresh batteries?
2. I didn't find that model at www.samsung.com (USA here) so I can't see if the TV needs to pair with the remote.
I have a Samsung BN68-04027A-03 and have not had a problem with the remote until the last few days. All of a sudden the remote is only turning the cable box on and off but not the TV. I have tried to resync the remote with the TV but it still will not turn off the TV. If I unhook the cable box and just try to use the remote with the TV, none of the buttons work. The only thing I have not done is remove the batteries and hold down a button for 20 seconds to reset the remote. I will try that tonight. I have also ordered a new remote as the one that came with the TV does not look like the remote that is provided for this TV online. Any suggestions would be greatly appreciated.
