I had the same issue with the camera going into safeguard mode. I took the bettery off and whacked it a few times over the speaker and it works fine now.

I have been having the same problem. Can someone tell me what I can do to fix it. I tried head cleaner and removing and re attaching battery and still nothing.

E04 Unit in safeguard mode : Remove and Reattach Battery I have had this same problem since my warranty ran out on my JVC DV camcorder. When I turn it on to record or play, a code appears on the display screen "E04 Remove and reattach battery. Unit in safegaurd mode." I have tried to remove the battery and replace it and I have the head cleaned. Twice I have brought it in for repairs but over time the same thing comes up. Can any one tell me what causes this and how to rectify it.

I had the same problem. I hit it on both side with my hand and it stared to work again. Will see how much it lasts ...

Rotation of the video head has stalled or too fast

E04 is a drum error, all the cleaning in the world wont change that. Contact JVC for service.

I am also having the EO4 error. I did open the cassette holder and view display, removed the battery and spanked the camcorder. After installing the battery the camera started working again.

I have a Dl-300 which I bought in 2000 and have the EO4 Saftey Mode problem, but it happens even when I have it plugged in. Also, the sound went on it, and so did the white balance. And I only use it sporadically. What a piece of junk! I here there is a class action lawsuit against JVC, and I want in.

hey guys i have this same problem with my mini dvm jvc(error E04) and i really want to get it fixed. PLEASE HELP ME

I´m having the E04 problem. The model is dvl100. The camera is out of guaranty. I´ve contacted JVC and theys said the repair costs about 300 Euros. I´ve already solved the problem. The problem exists every time i insert the tape. So in the exact moment the tape is entering i press it harder (to force the enterance), and the strange noise that i heard before the error message desapear, just like the error message. It´s a "foce solution" but it´s better then to pay 300 Euros.
