Just opened a ticket but....

Has anyone else had any problems with the power supply in the E5 going south?

Thanks,

Jeff

I had that happen to my E8s twice. The first time was only weeks after I got them and the retailer replaced the one without a problem. The second time was just recently when the speaker was just under a year old. PreSonus was very good about honoring the warranty and repaired it for free with a minimal of shipping lag time. Never have gotten an explanation as to what when wrong, or how I might prevent it in the future though.

Mine just went out too. I replaced it with the one that was in the holder and it blew out also.
My unit is JUST over 1 year old. I am hopefull that Presonus will step up and repair this!

Just happened to me!
I couldn't get them(tech sup.) on the phone today.
Fingers crossed that they will fix this.
My box is a little over a year, therefore out of warranty.
I just hope i don't have to pay for a design mistake...
Fuse blew during a mix session, changed the fuse and immediately blew again.
Hopefully just a bad capacitor...
I'm somewhat glad I'm not the only or first one....

It does seem like it is a design problem or a bad component in the design.
All of these units are just right at the one year mark when these are failing.
The MTBF (Mean Time Between Failures) of this component must be right at one year.

I too hope that Presonus addresses this issue.

They are going to repair mine for free!
I knew there was a reason that I liked Presonus. GREAT PRODUCT SUPPORT!

I have a pair of Eris E8's and one of them has the same issue that your describing. Fuses blow immediately and are really black so it's a major issue. I'm having it bench repaired by Presonus now so hopefully I won't have this problem in another year or with the other functioning Monitor.

Hi, my Eris e8 blowed fuse like you, it turned out it's a ceramic capacitor .1uF - 100V that burned out, The ceramic shrank so much from the heat that the two poles inside touched toguether, creating a shortage. I need to replace it. What's strange though, in my other Eris e8, it's a diffrent circuit board and have .1uF - 400V ceramic capacitor in it. The part cost almost nothing if you can solder it by yourself.

The capacitor 100V voltage rating is too low for either 120V or 240V. Sounds like it was a mistake. 400V is much closer to the mark. If the speakers are under warranty you might void it doing your own repairs. You need to be skilled soldering components around mains areas to ensure soldering is solid and strong. (Unplug before soldering!)
