Ahh so neither remote are communicating with the tv...
We have a couple of things that might have failed here...
First would be the IR sensor could have failed, this would need to be replaced, it is internal to the tv. This type of repair normally runs around $300-$400.
Next could be that the micro on the main board is not accepting the IR sensors input, this would not be good because the main board would need to be replaced, normally around $500-$600.
You can always try the good old reset, with the tv on, unplug it from the wall and let it sit 10 mins and then plug it back in, I hate telling people to do this because in all my years of tv repair, I think I have had this fix about 2 problems, but you never know.
If you know how to solder, use a meter and have some experience, I can assist you with the above repairs, if not then you will need a repairman at this point.
