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.

  there are some great tips on this forum.
  
  I used to get the e04 code but have switched from TDK tapes to JVC and I never had the problem again.
  
  HAS ANYONE HAD THE E04 CODE WITH A JVC TAPE??

  Im starting to see a trend here with JVC GR cameras. I myself use my camera in a housing and too many times it has shown the E03 and E04 errors. I also use JVC brand cassettes and i still have the same problems.. I have also had my camera serviced and the same problem still occurs. Head cleaning seemed to work for a while as did removing the battery for an extended period of time but the problem cropped up again tonight.
  I am wondering if there is an expert out there who does not work for JVC to ensure an unbiased opinion on how to fix this problem.
  Many thanks

    Hi, I have a GR-DX75US and had the E03 I also have all the service manuals needed to fix the camer and tape mech. If you cross reference the part #s and find you have the same tape mech I will send you the service manual in pdf form for $5. I bought these manuals and fixed my own camera for under $60. That's alot less when you compare paying $150 for someone just to look at it.

  Hi; just found this forum.. so let me explain what this E4 problem is all about. I'll try to answer all major problems:
  1. E4 is not depending on the type of tape
  2. There is a electric wire like a tape with a lot of wires; this tape is transparent and it is the electric connection to the rotative head. because of turning on and off the camera lots of times the end of this "tape" truyes to jump out of the connector. This happenes also at camcorders wich have been a lot in the sun.
  3. How to solv the problem: You have to hiold the camcorder in your right hand amd with the left hand you have to press quite hard with your fingers placed on the part where the LCD meets the body. This will bring the "tapes" connector back in the regular position and it is the only way to fix the problem for good without opening the device.
  
  I hope many of you will solv their problems with my help!

    Thank you! I had the E04 problem with our 300U, and this worked perfectly! I don't know how long this fix will last, but it's not like it's difficult to do.

  I have a JVC GR-DLV310U and have gotten this error message many times. I have found the only thing that works is beating the camera out of frustration. My kid's hockey game in the third period is when the @&*$#*#%^#% thing acts up usually. I've actually broken the LCD screen when I slammed it shut too hard out of frustration. Oh, also, the eyepiece didn't work due to the little ribbon wire connection which I got fixed after one year (under warranty). The wire breaks from moving the eyepiece up and down. Well shortly after I'd gotten it fixed under warranty, it broke again. So, overall, I would say this cam which I paid over $1000 for is a piece of crap. It still works intermittently, but I use it mainly as a doorstop...it just isn't worth fixing. My Sony works pretty good...bought it on EBay for $60...Hi8.

  I have had this same problem in the recent past and found that I was able to reset it, after playing with some settings I discovered my toes on the screen and thought I had fixed the problem! The next time I turned on my unit the same thing happened, unfortunately I was not able to reset it as of yet. I f I am able to do so I will send you a method . Although if you find the method first I would much appreciate the help!

    I have finally found a way to fix this camera after a year of missing out on pho ops of my 19mo old. Today 4/14/06 I found this forum, read the messages and promptly whacked the camera on the side by the speaker. Works fine for now. JVC stinks.
