I have the same problem and the same conditions.
The tweeter is good, 3.8 ohms.
Some points of solding (donuts), have bad aspect.
I resolder the power transistors to the PCB and I solve the problem.

Same here. Streaming from Spotify from iPhone5..... every 10 minutes enters sleep mode. WTF? No idea how to get around it. Only FW upgrade I guess, if there any...

I had a problem with the speakers not working properly. The green lights lit, but the amount of sound coming from the speakers compared to that of the sub was much lower.
I decided to take it the speakers apart.
I found that the magnets on the speakers had moved forward slightly in the plastic cage they sat in. I pushed them back as far as they would go, and Hey Presto! working again!
I hope this helps someone!

i have the same problem. don't as yet have a solution

What passkey do I need to connect to a monitor

PAIRING THE JBL SB400 FOR WIRELESS OPERATION After turning the soundbar and subwoofer on for the first time, you will need to "pair" the subwoofer and soundbar so they both operate at the same wireless frequency. To pair the units, press the Wireless Pairing switches on both units within 30 seconds of each other. The units will communicate with each other and operate at the same frequency.

You are not summing the signal you have one side out of phase with the other. Swop + & - around on one speaker.

It blows the fuse because a semiconductor device has developed a short (in otherwords acting like it was just a piece of wire). Because of the noise I would suspect the main amp device is the cause. It will be most likely on a heatsink.
