It may not be able to do so unless you have the manual for it and the codes are available. It usually a matter of following the instructions in the TVs manual for the remote control. It can be a bit of trial and error finding what code works.
I found the codes but do not have the manual, TV was a recent gift. I tried holding the power button down several seconds but the unit does not blink twice to allow me to enter the codes. I also positioned the unit to the cable setting. Any Ideas?
