No, I was just able to check the speaker at practice today and it appears the fuse is inside the cab. There are no screws around where the fuse is located and nothing looks like it pops out.

I'm not sure what to do now, I guess I'll do some research to find out how this is done.

"I'm not sure what to do now, I guess I'll do some research to find out how this is done."

After a cursory web search, I didn't turn up much of any useful "how to" info for those speakers. Hope you have better luck.

I think it's ludicrous that you have to open the box for a fuse! I mean, what if you're at a gig??
What a PITA.
Even my budget-priced Behringers (B212D) have the fuse holder right at the IEC socket!

A quick YouTube search produced several videos for fuse replacement for the EON series. Looks like you need to make sure you replace with a "slow blow" fuse in the proper amperage.

I found one useful video on YouTube, but none about the exact model of JBL speaker I have. Oh lord, I may reduced to asking advice in the Pro Sound department of Guitar Center! (:oD

I had the bigger brother, Eon315 and had a fuse replaced. I seem to recall the fuse was on the back between the on/off switch and the IEC electric input...in that little area that looks like a barbell.

Check the link below. When it opens, go to the 5 small photos under the large photo. CLICK ON CENTER PICTURE. ENLARGE AS NEEDED.

I do not know how to open the little sucker, but a quick call or email to JBL Customer Service should get you all the information you require.

Tony - That's it, but how do you get in there? There appears to be no way to open that little piece of plastic with the image of a fuse on it.

Look closely at the little fuse 'door' and you'll see there's a tab that points to your left, into the IEC power socket.

Stick your left index finger in the IEC socket and hook your fingernail under the tab. Pull. It should pop right out.

Sometimes they are tenacious, so you can do the same thing with the tip of a common screwdriver (about 1/4" wide) and the little fuse tray will pop open

like a little drawer.

Peegoo - Wow, thanks so much! I wish I had these speakers at home, but they're at our drummer's house where we practice. I'll have to buy some fuses and "fix" the speaker this coming Saturday.

You'll need a T3.15A 250v fuse for that one.
(look at the magnified picture of the control panel to the left of the IEC socket)

The "T" is a slow-blow fuse.

How do I know this??? Ask Peegoo! ;^)

UPDATE - I changed the fuse and the speaker still won't power up. I guess it's dead.

the thing that's a drag w/EONS is they're not worth fixing a lot of the time

Bummer, I think we were all hoping it was an Ockham's Razor situation.

If it's no longer under warranty, it might be worth opening it up and seeing if it's the *next* simplest thing like a loose wire or bad solder joint.

Hopefully it won't involve a cost prohibitive repair or full on replacement.

Get a meter and test that power cable for continuity to make sure the little electrons can run from one end to the other.

There may be an internal fuse (one or two) in the power supply section.

Pop the hatch and look in there next to the power transformer...probably a little glass tube about 5/8" long. Some are white porcelain, some are black.

Many clip in, but some are soldered in.

They look like this.

Thanks Peegoo, I'll give this a try, once I get this speaker from our practice space.

I spent some time yesterday searching for a schematic of that speaker model to see if there are any internal fuses, but came up bust.

Guess you'll have to crack it open & have look-see.
