Hi,
my UL MK3 Hybrid refuses to boot - it powers on (via firewire and/or via DC input), but the screen stays on:
###########
UL MK3
Boot v1.00
###########
No clue what happened, It was working the day before - I left my PC ON (but on sleep mode) as usual during the night - the day after, this problem arose.
I have no clue what to do, I opened a ticket on the MOTU website - https://motu.com/en-us/accounts/techlinks/178134/ - hopefully, someone can give me some directions.
From a quick search online, it could be a hardware problem
- I live in Norway, but I usually go to Italy (my own country),
so If you know of any technician/store that can have a look at it in one of those countries that will be great!

Re: UL MK3 Hybrid stuck on Boot
Can you reset the unit to default?

See this recent thread about burnishing the ribbon connectors. Sometimes, it works.UltraLite-mk3 Hybrid / UltraLite-mk3: Press the Param/Setup knob until the LCD screen reads "UltraLite mk3 SETUP" or "UL Hybrid Setup". The LCD screen will quickly flash to "LCD CONTRAST". Turn the Param/Setup knob all the way to the right. The LCD screen will read: "Factory Defaults Press [Value]". Push the Value knob once. The LCD screen will display "Are you sure? Push [VALUE]". Push the Value knob again to confirm. The LCD screen will read: "Initializing...". The clock value in the LCD screen will flash when the reset is complete.

Re: UL MK3 Hybrid stuck on Boot
Thank you so much for your reply - I am not able to reset the device - as I power it ON I get the Boot screen and no way to interact with the other knobs.
I tried to disconnect and re-connect the ribbon cables - unfortunately, no changes
- I tried it several times.
I am attaching a pic of the inside [1] -- maybe some expert eye can have some guess from it - Also, if a zoomed-in pic in a particular part of the board can be of any help, I'll provide a link to it.
Thanks for any help!!!

Nothing is standing out, unfortunately.
