Marshall Woburn III shuts down completely after 2–3 minutes of music playback
Hi everyone,
I’m having an issue with my Marshall Woburn III and I’m trying to figure out whether it’s a known problem or if my unit is defective.
What’s happening:
The speaker powers on normally.
It can stay powered on indefinitely when idle.
As soon as I start playing music via Bluetooth, it plays for around 2–3 minutes and then shuts down completely.
All LEDs turn off.
The power switch remains in the ON position.
The only way to get it working again is to unplug it from the wall and plug it back in.
Things I’ve already tried:
Factory reset (holding the media button for 10 seconds)
Re-pairing Bluetooth
Different music sources
Plugging directly into a wall outlet (no extension board)
Checked firmware version in the Marshall app
Firmware is up to date (v8.2.2)
Additional details:
Volume is only at a medium level.
The speaker gets only slightly warm, not hot.
It does not shut down while idle.
The issue only occurs when playing audio.
The speaker is still under warranty.
Has anyone experienced something similar with a Woburn III? Does this sound like a firmware issue, amplifier fault, power supply issue, or something else?
Any help would be appreciated before I go ahead with a warranty claim.
Thanks!
