There is a small 5V power supply inside the unit that has a track record of failing.
It's a relatively easy fix if a suitable power supply can be found. The one I used is backordered right now. Required a little modification but works fine.
Logitech Transporter Service
I know this is a long shot, but I have a Logitech Transporter that simply atopped powering up one day. It’s a nice sounding piece that I would love to build an office system around, but I’m stymied as to where I can get it serviced. Any suggestions would be most appreciated.
