This is the type of remote

Hi @Irene_41  A blinking red light tends to indicate low Batteries or unpairing from the  Remote.  If not the batteries try   pressing  the Return and play/Pause Buttons simultaneously for  more than 3 seconds to reset and display pairing window, also check there is no obstruction.

What model tv do you have?

[Patc2]

I have a CU7000B tv. Remote has no microphone. I use Optimum cable TV which has a remote with microphone. Can I buy a Samsung remote with a remote to use with my cable connection so I don't have to use two remotes if yes what do I buy?
