Do a search of this problem and you will ind that every JVC owner is having the same problem. I finally got mine "reset" by powering the unit on in payback mode while holding down the "play" button. Then, turn it back off and power it on in the camera mode while holding down the "rec" button. This seems to have reset it and I've not had anymore issues SO FAR!
Good luck with it.

    I read somewhere on one of these chats date mid 2009 that if you tap the bottom of the camera it will fix the problem. I tried it and it worked perfectly.

    Tapping the bottom worked! I did it with a fully charged battery and tapped it pretty hard all along the bottom with my finger tips and it worked after 4 tries. Thank you fuzzmaker2!

    this is no joke. i just did the very same. i rasped it pretty hard about 8 times on the underside with the handle of a metal kitchen knife (after all what had i got to lose). voila! camera now works! obviously something inside is getting stuck and this frees it. it got this e04 when it had been idle a long time so clearly something gets jammed when the cam is not in use for a long time. that camera was out of action for a few years but just gave it to kids as photo was working. i thought i'll try one more time to fix it. sorted! this is not the only device i have fixed with a good hard knock. weird huh!

I tried turning it on to play while pressing the rewind button and it worked. This may have been a coincidence, but I'd love to know if it works for anybody else.

Gr-dvl-520u trying to record or playback tape it goes into safeguard mode within 5 seconds. alternatly pressing play and still every 3 seconds advanced the playback without it going into safeguard mod

According to,

"JVC notes that you are also given a malfunction code when the unit is placed into safeguard. If it displays code 01, 02, or 06 you should remove
the battery and powersupply and wait for a while. Code 03 and 04 indicate that you should eject and reinsert the tape.

If neither of these solutions work, your only alternative is to bring it to a shop or send it to JVC for diagnosis or repair. Unfortunately, there is no other way to clear the condition."

If you are getting E03 or E04 errors on every tape you try, it sounds like a servicing is required.

Unit in safeguard mode

I found the solution on another web site. You just eject the tape, and then give the camera a few sound whacks near the microphone (I tapped mine of a carpetted floor). Believe it or not this seems to work! My camera had been in "safe mode" for over a year without any success in fixing it. I tried the above method having lost all hope of ever using it again, and presto, the think came back to life! Can't say how long it will last, but at least it's out of safe mode;-)

Problem with jvc gr-sxm58

Do you happen to try with another tape? if so, it needs repair, mostlikely the capstan motor need to change and it needs hinger skill to do this, since you have to adjust it after replacing.
