Hey everyone,

I figured I'd reach out to see if anyone has troubleshooting suggestions for a friend of mine with a Kronos X that is spontaneously rebooting and drops an error when rebooting.

Here's the scenario: He'll be in the middle of anything/nothing/programming/playing and his Kronos will pretty reliably crash. When I say crash, I mean a spontaneous reboot. The screen freezes, the sound stops and sudden reboot. When this happens, the Kronos will try and restart like normal but gets about 20% of the way loaded and then says "SYSTEM STARTUP ERROR" (Turn the Kronos off, wait, turn back on, yadda yadda)

Okay, so some other oddities that have happened:

1) We tried to swap the SSD from the factory to a newer SSD. I've done this in both of my Kronos boards with the *exact* same SSD he's using, and I have the same in my other two. When he gets to the formatting SSD portion of the install, the whole thing just freezes.

2) We've tried reseating ram. No dice.
3) We've booted the motherboard itself into Linux using a boot disk, everything works as far as we can tell from a motherboard aspect.
4) Replaced the motherboard ANYWAY, same issue with the SSD. (Same behavior, probably not the motherboard)
5) When we put the original SSD in, it'll get past the formatting part and will actually boot up, but then does the spontaneous reboot and crash like mentioned above.

Now my gut feeling is that it's the power supply being stupid. That might explain the SSD, since the faster writing of the newer SSD's *might* take more power? External drives hooked up didn't seem to work either which was a different symptom I forgot to mention above.

Like, to me it just SCREAMS psu, but I wanted to run things by everyone here of a troubleshooting mindset.

Is there anything really obvious I missed that would help eliminate/confirm that it could be the power supply of the Kronos X?

Suggestions? Ideas? Help!? lol

I would guess you did the obvious- hook up and use UPS. Reseat the power cord , both ends. I would substitute another power cable as they are plentiful.

Disconnect all USB devices inc the nano pad

How is his Kronos on available SSD storage ? Is the file structure on the drive fairly clean ? Or is it a jumbled mess ?

It also could be software. The OS sounds unhappy about something. If you have a solid power connection, re-install the OS.

Thanks Greg,

We've covered all of that too, and the OS is a completely fresh install.

Have you ruled out bad RAM sticks?

Other things I would suspect would be all connectors like USB jacks, etc. If not done already, use air spray and shoot everything that might accumulate dust like MIDI, USB and audio jacks etc. I would also air clean the MB as well, etc. Just a thought.

Diagnose in your case needs lab investigation but I'll try to guess !
- If you've booted the motherboard itself into Linux using another boot disk using the same PSU and Ram check was successful ,
then it's not a motherboard issue.
- PSU instantly unstable behavior could cause this initially and then SSD data curruption follows as a consequence !
- Newer and faster SSD have usually lower power consumption than older.
- Your issue is mostly focused on SSD (probably partition boot sectors) that might can't be recovered by OS formatting !
- PSU usual malfunction symptom is that Kronos do not respond at all after shut off !
- You can try to externally format SSD in Fat 16 , swap your Kronos PSU , use a UPS and try to reinstall DVDs resources v1 up to v2.

Good luck

I'm running into the exact problem on a brand-new Kronos 88 (it reboots and fails to restart unless powered down). I'm currently restoring from DVDs, but first attempt failed on disc 3. Did you find a solution to this?

The only time my KRONOS spontaneously re-started the temperature was very high. Correllation?

Sadly not in my case. I'm having it exchanged since it's only a week old.

is it a back to the retail dealer exchange ?

Or did Korg authorized service handle the switch to a new board ?
