Are you positive you got the connector on correctly? Many of these plugs will go on, even if they are shifted off to one side(leaving some pins not connected). I would take another look, and maybe disconnect first to look for any bent pins

Did you ever find out what those red lights mean? I have a similar problem. Mbox 3 Pro doesn't power up and one red light turns on and off after few seconds. I noticed that they "behave" differently if you use different power adapters.

regards
I have a problem with my mbox 3 pro
I upgraded to the latest driveres card for windows that are these

Fixed: Tuner & DSP Effects stop working after updating firmware (NOTE THAT if Tuner & DSP Effects are not restored, the unit May require a repair)
Mbox Pro Firmware Updates to v1.0.4
Windows 8.0, 8.1

but turning off my audio card does not catch me now, will not start.
not turn on the lights.

I read these messages on this forum and I have uncovered my card m box and all is well within it, in fact when I connect the power supply comprises a red light inside, which I saw when he had disarmed.

I need help to fix this please

Anyone get this working? I updated my drivers on my mac. After that, my interface never turned back on.

Tried different cables, installing older drivers, different port, and nothing. Interface doesn't turn on.

I did however notice that if I plug in the power cable while having the monitors on, I do hear a sound as if something working. But it just won't turn on.

Also, it does not show a firmware version after the update.

Any help/suggestions would be appreciated.
