did you ever solve your e04 problem on your jvc camcorder.. i am having the same problem.

Hey guys, thought that I was the only one with the coded denial. Anyhow did all the reading I could, I tried something very simple, I do have the cheaper tape, so what I did was take it out of the unit, play with the little pin on the tape by opening/closing it, that worked. Then I gradualy placed the tape back in its dock and left the tapes gaurd open as long and as wide as I could. Seen to solve the same error message, and just think I have been messing with this thing for days, glad I didnt take the screwdriver to it. So good luck, I honestly think it is the tape and not the recorder, something is preventing the tape gaurd from opening?????????????????

My JVC is saying the same thing now. CONDENSATION, OPERATION PAUSED just sent it in for the lens cover error and now this! Have you figured out what to do? Chris

i had this same problem - tech guys looked at it and couldnt work it out. so i looked into the tape mechanism and what did i see ??? the flimsy little tape guide at the back of the tape cradle(the one on the top at the back) was bent a little. When this is bent down a little it stops the head from rotating properly. bent it back and it went straight away. look in the unit yourself and see if it is all straight ! dave

I accidently submerged my Gr-DVL300 last week, and now have no response to attaching the battery. Should I throw the camera out or are there some options I have for opening it and trying to see what may be damaged? Thanks. - Jack.

Hi All, I had a JVC DVX9 camcorder (£1200 retail at time of purchase). I have had all the problems - condensation message, clean heads message and error EO4 remove and reattach battery message. Unit was just out of warranty when problems started and after following various recommendations from JVC I again took there advice and submitted it to a store (recommended by JVC). Paid my money for it to be looked at and then waited and waited and waited. Jvc kept saying they would discuss with store and when I finally tried to recover the unit the store had gone into liquidation. I could not get my equipment back and JVC simply washed their hands of the matter. Bottom line is DO NOT BUY JVC. I made it quiet clear that I would not purchase any more JVC products unless they sorted something out and - to date - am still waiting. WOULD NOT RECOMMEND JVC TO ANY BODY AND IT WOULD SEEM THAT IT WAS NOT A ONE OFF FROM THE NOTES HERE. JVC OBVIOUSLY HAVE NO INTENTION OF HELPING AND WOULD CONSIDER OTHER ACTIONS IF ANY BODY HAS SUGGESTIONS.

I came across Error 4 this past week on my GR-DVL300. Like everyone else, I removed the battery and and put in back in only to find it did not clear the error. I stumbled across the postings here after doing a google search and found the one about hitting the camera on the side. I wacked the camera on the side just once and now it is working! I'm glad that is all it took and I am glad that I found the posting on this site!

IT WORKS !!!!! Doing what someone just posted works! To get the CONDENSATION message to go away, cover the lens with your hand. This will cause the camera to display a different message, "LENS CAP". Now you can remove your hand and you should no longer have any error messages. Duhhh, go figure?? Terry in Texas

yeah hit the camera on the side it actually works after half an hour of removing and attaching the battery i hit it and it went away thanx:)

Hey I just wanted to say that hitting my camera did in fact work. The "safeguard mode" thing went away after I hit it a couple of times.
