Yes, the remote control is generally compatible with your TV. If only the power button works, try the following:

1: Manual pairing: Press and hold the "Return" and "Play/Pause" buttons simultaneously for about 3 seconds until pairing starts.
2: Check batteries: Weak batteries can cause connection problems.
3: Update TV software: Make sure your TV is up to date.
4: Reset the remote control: Remove the batteries for approx. 30 seconds and then reinsert them.
