Hello, My name is ***** ***** I'll be assisting you. I'm sorry you're having problems. I'm reviewing your details now and will reply shortly.
What remote are you referring to here- is it the original TV remote, or your cable provider remote please?
Also, what have you tried so far- any reboots, unplugging, etc.? Lastly, are you using a cable BOX with this TV?
I was just wondering if you needed assistance with the question you posted here?
