McIntosh MB50 Media Streamer does not power on


The unit worked fine until now.  

I tried to factory reset it, pressing INPUT and STANDBY/ON buttons simultaneously as per instructions.  I do not recall if lights flashed after holding the two for a few sec.   The reset may not have been completed.   Now the unit is a brick. It won't power on.  I see an LED inside glowing indicating power is reaching the motherboard, but no other sign of life.

Any help or similar experience to root out any obvious troubleshooting steps here?   McIntosh MB50 manual is garbage. 

Appreciate any help or ideas. Thank you!

I am thinking about buying an MB50 as I use Play-Fi already. IDK how to fix your issue but have a question. Have you tried it purely as a streamer connected to a DAC? If not, how to you like the overall SQ and as a preamp?

Thanks

The good news is there is a usb port on the back for firmware uploads. I don't see the firmware on the website but ask Mcintosh to e-mail it or send a link so you can download it. This happened to me once with a Polk S6 Playfi speaker and they sent me the firmware with instructions on how to install it. I loaded it on a thumb drive and followed the instructions, NP.
