I have a JVC cybercam #GR-DVF21. I am having the same E04 error. It has come and gone, but now has won't go away. JVC's response, "pay for them to fix it." I payed almost $900 for it and didn't expect so many problems. I realize this law suite probably already happened, I would like to know the results of your pursuit. If the law suite is still going on, what is the progress, & how would a person go about joining. Thanks for the help.
