One thing that seems super weird is that the longer it’s left turned off, the longer it takes before it crashes.
Makes me think it’s maybe, possibly, a tiny bit, not hardware related.
I dunno, I’m just trying to not be too bummed out, seems f&*ked.
- Open it up and make sure all internal cables / connections are seated correctly.
- Try a different power source, i.e. different PSU.

Mourning can be extend then, Midi tracks also suffered.

This happened to me the other day, I unplugged everything and checked psu connections etc turns out I had knocked the cf card ejector
When I reinserted the cf card it worked fine
Unsure if related, but I’m using a beta os

Decide if you’re gonna ask questions in the “is octatrack worth it in 2023” thread

So, after resting overnight, the OT ran for about 20-25 minutes before it crashed, I wonder if that gives any tips about what could be wrong with it?
Is it possible a component is overheating?
Have you reseated the ribbon connectors?

I would also take a closer look at the CF card slot. Maybe a pin is bent or broken?

I’m not entirely sure if I’m comfortable opening it up while it’s still under warranty tbh.
CF slot seems fine, this morning it loaded and played a project from the card for about 20-25 minutes before crashing. All static slots.
lol you weren’t the one that was dismissive mate! Glad you got some useful pointers - always plenty to try before needing to send it off for Christmas.
Times like this I’d try and summon the OT support guru themself @sezare56
Although it’s 1.40A that is the latest official release from Elektron (and what ships on the boxes).
I’m not really sure why they use the ‘A’ designation.
Overall this forum is unbelievably helpful, unfortunately this seems to be something that even the OT forum masters might have to wash their hands of.
Thankfully there’s still a few months of warranty, just a bummer that I finally have some time over the holidays and the OT chooses yesterday to take a vacation 
you really don’t want that. I think the only way is to reset the part and maybe format the sd card. maybe he’s trying to boot from some file and can’t make it. much luck!!
In the video in OP, you have the INSERT COMPACT FLASH CARD message.
Do you have this message every time it crashes ? Maybe it wasn’t inserted this time.
Did you try with another card ?
In Test mode, after a crash, what the ATA line says ?
Nothing particular to add, as said, support ticket, ribbon…

Hi sezare, that was just me testing if the crash also happens without the SD card. The same thing happens with the right SD card inserted. Today I could even load a project, play it normally for about 20-25 minutes, then the device crashed.
Did you try with another card ?
Yup, same problem.
In Test mode, after a crash, what the ATA line says ?
It says OK.
Nothing particular to add, as said, support ticket, ribbon…
Yup, thanks. Personally I’m not going to try fiddling with the ribbons while it’s still under warranty 
also don’t have the right T8 screwdriver anyways!
A support ticket has been created and Elektron told me to send it in, they already sent a shipping slip! Needless to say, the service was exceptionally quick, so in the New Year I’ll hopefully be back to posting beginner questions on the forum!

you could try flashing the firmware, even if its the same version in case it got corrupted. worked for me on some devices I used to have (like the OP1)

It has alreadt been mentioned, but try another power supply before sending it off.
Tried that as well, still crashed 
Yeah, tried this as well…
sending it off today

How old is the unit?
A time based failure, rather than an operation based failure, could indicate an internal capacitor dropping out of specification.
When powered off, internal capacitors discharge themselves slowly. Turning it back on fills them up again. If the cap is causing a drop in voltage, it can cause a microprocessor to get confused and lock into unpredictable states.
No amount of resetting or seating cables will replace a failing capacitor.
