Not sure i can help with the led problem but i just fixed a hissing problem with one of my BX5a monitors. It developed a hiss when on (both tweeter and bass) and a very loud thump when switched off. I found a slightly swollen power filter capacitor on the internal board. They are the two biggest black capacitors, labelled as 25v 6800uf. Only one of these was bulging. The tops of these should be totally flat. The indented X on top of the caps make any bulge easy to spot. Worth opening it up and having a quick look. I could only find 35v 6800uf caps at my local electronics store but they did the job ($3 each). I swapped both out and it's now working great. An easy DIY fix, just be sure to always have the power cord unplugged before you put your hands anywhere near the guts of the thing. Hope it helps.
Replace the caps with 50v 6800 uf ones. 25v is way too low for monitors. bad choice on m-audios end. you will most likely have to solder new leads on the board and mount the caps off the PCB because new ones are so much bigger. easy DIY fix though. happens all the time with this model.
just make sure you get the polarity correct on those caps and dont forget to discharge the ond ones BEFORE you go working on it! (just ground the cap)

Hi, cases like that always comes u. Earlier you said just replaced it, that's not too good for anew monitor speaker.
You could test the fuse inside the speaker if it's still working, might be power fluctuation that might have caused it to blow.but you need to test it. If it is the fuse,fine! you can replace it, it does not cost much to replace.
Also if i can recall,most new stuffs always comes with guarantee with it,right?. I would suggest you could take it back and get a replacement, and i guess if they see it,since it is on guarantee,they can fix it for you without even charging you a penny.
I have a pair of BX5a monitors hooked up to a video editing suite. One
of the monitors is off. They are powered to a working electrical
supply. They are driven off a Mackie DFX-6 with a 1/4" unbalanced
connection. No blue light on the monitor, no sound or hissing on
Hook a graphic equalizer between the piano and speakers, and turn down all sliders above 8 kHz. Since the highest note of a piano is 4186 Hz (4.186 kHz), you'll still hear all the notes but cut the hiss. If the hiss is coming from the speaker's power amplifier (in which case the equalizer won't help), turn down the speaker volume and turn up the piano volume. Live instruments generally need some doctoring to sound good through high-quality stereo equipment, as they only produce a limited range of frequencies whereas good speakers reproduce a lot more - including hiss.
