CPU.
1) Disconnection in the middle of the signal line.

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.

According to http://www.techlore.com/article/10974/JVC-Camcorder-Stuck-in-Safe-Mode/,

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

Safe gaurd mode can mean a number of different problems, most of the time being mechanical, if you are not a tech. you will need to take it in for service.

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.

Put it on fire and buy some good camcoder<br />

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!
