unfortunately you must use original remote to perform this function

This is either 1 of 2 things, first it could be faulty panel tabs , in this case, there is nothing you can do and is unrepairable....2) you could take the back off the tv and you will see 2 ribbons going from your t-con board to the panel tabs (top center of tv) remove them carefully and reseat them. This is a common problem. Tv repair tech 15 years! Best of luck.
