Nintendo Wii Sensor Bar or Remote Problem.?

I have a problem wid my wii's accuracy .in resort while playing table tennis the racket gets stuck at one place(mostly 2 da right) nd da frisbee is not soo accurate.i dunno wether da problem is wid da sensor bar or da wii remote plss help……….

Suggestion:

Turn off the lights and use a camera or camera phone pointed at the wii sensor bar. You will be able to see the infra red led's in a line one beside the other. Check they are all working.
