Fuse in the HD110/111 at DVinfo.net

There's a lot of references to the fuse in this camera on this board. A lot of it seems to be based on supposition, conjecture and reported comments from service engineers.

There is some overlap in the following note with this thread:

Apologies for this, but I think the issue of the fuse comes up often enough in this forum for it to warrant a short note by one who has been there!

The story on the fuse is this.

1:There IS a fuse. There is NOT a circuit breaker

2: The fuse is only "user accessible" if you are prepared to take your camera to pieces. Both side panels need to come off, a dozen cable blocks need to be disconnected, then the Power Supply board can be accessed by removing the battery mount.

3: Having done this twice in two days, I can say only undertake this job if (a) your camera is out of warranty (b) you are a long way from a service agent and (c) you are confident that you know what you are doing.

4: There is a page from the JVC service and repair manual that shows how it should be done. I don't think JVC would thank me for putting it up here. But if the Forum disagrees, and would like to see it and JVC don't ask me not to, I will post it. I hesitate because it was sent to me in extremis by a JVC service agent, and I don't want to make their life difficult.

5: The fuse is NOT a standard glass and wire arrangement. It is an electronic component, soldered to the power supply board. It is a small, white unit, at the bottom right of the PS board. "F1" is printed above it. There is no way of seeing if it is U/S visually. You need to put a dwell or continuity meter over the contacts to see if it carries current. If it does, it's OK. If it doesn't, it isn't.

6: I think it would be fairly straightforward, if you got this far, to de-solder it from the board, and replace it, if you could find another component. I don't know how easy it would be to find another component.

7; Re-assembly is the reverse of dis-assembly. There are no hidden traps.

Hi - I blew the fuse in my HD100 somehow. Can you send me the service manual page you referenced, I'm far from a service agent and hoping to get it done locally, I've already removed the old one and found a replacement fuse from jvc. Thank you
