Facing TV Problems? Ask a TV Technician.
First, check that the batteries are good in all affected devices.
If they are, then there may be interference from some other bluetooth device.
Try turning off all other devices in the house that have bluetooth capability (e.g. cell phones, playstations, etc).
Once you shut everything off make sure the TV is turned on and try using the 3D glasses and remote control again.
Let me know if they work for you.
