maybe you need more batteries (this happen to me before) or you might as well move the radar stand on the T.V. wrong.

The batteries might not be up the right way, or the remote might have genuinly kicked the bucket.

have u tried pressing the red button on the wii and the control at the same time? if u had then i don't know and if u have not, try it

do the batteries work like the ones u put in?? buy new ones...
