Error codes E04 and E06 on my JVC GR-D30U camcorder, what can I do to get my tape out.

The error code E04 on a JVC Camcorder GR-AX2 indicates a problem with the cassette mechanism. This could be caused by a number of issues, such as a jammed cassette, a malfunctioning cassette compartment, or a problem with the camcorder's loading mechanism. In order to fix the issue, the camcorder may need to be serviced by a professional. In the meantime, you can try removing the cassette and reinserting it to see if that resolves the problem.

good luck

Condensation message appear? Leave it on for sometime eventually it will disappear, if not visit your nearest JVC Service Center.

Here is some information regarding the E04 error message from http://www.techlore.com/article/10974/JVC-Camcorder-Stuck-in-Safe-Mode/:

"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."

This doesn't seem uncommon, and indicates a bad tape is loaded, or unfortunately, that the camcorder requires servicing.

take a screw driver and open it up.

E01 means Mechanism has not fully loaded up to the stop position
E06 meansTape drive motor is not rotating or stalled.
Thses two faults indicate a tape jam. please remove the cassette and insert a new cassette.

there was a hole under the tape deck.. u can try to force;y open it right there

Eject tape leaving cover open and remove battery. Re-insert battery and re-insert tape also leaving cover open. Keep repeating this process until eo4 message disappears. This worked for my GR-DVL100e after about four repeats. After getting your camcorder operational, they say it is good practice not to leave tape in camcorder when not in use.

i had the same problem with my cam JVC GR-DVL309 and i solve it.
HOW!
Eject the tape, reinsert it BUT while the tape is going down to read, push the door with your hand just a little bit to right side just a few seconds while is reading the tape and close the door, (i had done this 2 or 3 times) this way i have solve the E04 Error, now i can record and play with my cam.

DRUM FG
In the case there is no DRUM FG input in the
drum rotation mode for 4 seconds or more. This
error is defined as [E04], and the mechanism
mode is shifted to STOP with the pinch roller
set off.
1. The drum cannot be started or drum rotation is stopped
because tape transport load is too high.
1) Tape tension is extremely high.
2) The tape is damaged or soiled with grease, etc.
2. The DRUM FG signal is not received by the syscon
CPU.
1) Disconnection in the middle of the signal line.
2) Failure of the DRUM FG pulse generator (hall element).
3. No drum control voltage is supplied to the MDA.
4. No power is supplied to the DRUM MDA

I had this same problem, and indeed it was from leaving a tape in the camcorder while in storage. All I did was remove the tape and put a new one it. Solved my problem! Thank you!
