Ok, my guitar for guitar hero has been working fine.  But today it seems to have some sensor issues.  I tried moving around the sensor bar on top of my tv but that doesn't seem to change anything.  When I play, it seems to lag and it doesn't seem to catch hardly any of my playing.  Anybody have any idea what could be wrong?  I thought about checking out the sensor on the guitar but I don't know where it's located.
