Try this... this has been useful for me two times... it's a little weird... but... works... beleive me... 1.- unload the camera... no batteries.. no tapes.. ok? 2.- with your hand ( 2 or 3 fingers...)hit the bottom side of the camera ( several times )... there is a sensor causing this error.. 3.- try to operate the camera.. it's true !!.. it's worked to me 2 times... write me back if succeed !! !!! sorry for my english !!!

I was geting JVC error E03, decided to try the empty, upsidedown whack. Repeatedly whacked with satisfaction, and....IT WORKED!!! Thanks for the tip, now I can get my tapes copied to DVD ASAP.
