JVC GR - DVL300

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 understand all your frustrations relating to DV camcorder issues but dont alot of high tech products have issues..... most new products are built down to a price point and are early to market to get on top of competitors thus perhaps not meeting the rigorous testing once given to products.
  All manufacturers have issues , some more than others and whilst you may think that all of the feedback here spells major failure,,,, this is the WORLDWIDE WEB you are getting a reaction from. There are alot of people without issues.
  Generally the problems are caused by tape... just accept to use Panasonic and JVC tapes also dont mix ME and MP tapes(chemical reaction can occur), connector issues that can be fixed by clean, crimp and seal techniques and occasionally mechanical issues. PCBs can suffer from solder issues and then require rework.
  Remember camcorders are mechanical devices and regardless of hours of use can suffer from heat(left in car), grit and sand(beach/desert), vibration and impact(travelling), and fluids(rain, fishing, surfing, etc)... issues can and do occur. Often customers lie and deceive only to be shown footage recovered of them doing that which they have denied.
  If you keep having the same issues repair after repair then more likely the repair undertaken was not thorough enough or lacked the resolve to truly be effective.... take it up with your repairer.

  i have the same problem. most times it was due to the moisture in the air, early morning dew, or just too cold, i have found that removing the cassett and and reinstaling it sometimes works for me. most of the time.

  I have been getting E06 error messages and getting mangled tape sticking out of the little cassette. So I cleaned the heads with a Qtip and alcohol and bingo! Shouldn't say this too soon but it seems to have fixed the problem.

  I have the same problem with my DVL300, there is something that realy works!
  Eject the tape (if the camera allows you to) take the tape out.
  You can the a transparant LED at about the middle of the tape.
  Below that LED there is a flex-foil (browncoloured), when I carefully put the flex foil back in position (towards the camera) the camera works again without headcleaning or removing the batt.
  I guess that the tape eject system pulls the flex-foil out of position and after hundreds of time damages the flex untill you gat a bad contact there.

    wow, thanks. that had an immediate positive effect. I just sort of pushed on the flex tape with a stick toward the body. instant gratification.

    You saved me! At least a couple hundred $$$. My JVC Gr-DVX10 made funny noises in tape transport, kinda as if idleing like after tape rippes. Tape was o.k. No or jagged pixlized output at playback, even with different tapes. Funny idleing noises also during taping. Sporadic headcleaning and fatal error - Remove & Reattach Battery messages. I followed your advise with bending hybrid cable towards cam-body and voilá we're back up & running. Who would've known. Thanks. Mike

  I have the JVC DVP7, and get the EO1 message when a tape is inserted, then I hear a mechanical buzzing/spinning/vibrating sound, and it pops the tape back out. I've tried resetting, using different tapes, etc. What should I try? I've tried to search through many of the posts here but didn't find a solution? Thanks!

  Please remember that these camcorders have TWO batteries. Try replacing the memory cell battery. On my camera you eject the tape to get to a plastic cell holder.
