A problem has been detected

Hello, I have problem with my Kronos X73.
4 months ago I had a problem: When I was starting up Kronos, on the display I saw: "A problem has been detected. Please turn the Kronos off, wait for a 10 sec, and then turn it back on." Then I had a problem with starting of Kronos- maybe 1 out of 5 attempts led to succesfull starting Kronos.

I had an old OS 2.0 and after advice of Service a new was installed (OS 3.1.2.). After this reinstalling OS a problem was solved. But only for a short time. The last weekend during the concerts - Kronos was turned off itself and I saw a notice: A problem has been detected. Please turn the Kronos off, wait for a 10 sec, and then turn it back on" again. It was during a concert, it was very complicated for me...

Please, can you give me an advice?

I have seen this message several times.
Once I noticed that this message and black screen was probably related to some vibration me or someone caused at/near Kronos.
I opened Kronos (bottom lid), checked/touched all visible cables/connections, reseated two memory chips and did not see message for long time again.

Few times I have seen this message and seemingly it was related to some power surges or fluctuations. Adding UPS and surge protector and grounding properly my gear hopefully reduces that risk.

At home studio this black screen message is just annoying, but also have had couple embarrassing moments on stage. I usually have two keyboard rig (Kronos and some other) on stage and can handle that.
I think that Big Artists have spare Kronoses with them on stage

This is not normal. Your Kronos has an intermittent problem which I believe should be looked at by an Authorized Service Center.

I moved my K1 and now my K2 around a lot with over a 100 gigs and rehearsals a year and it has been rock solid and never let me down.

This is the same issue I had almost 2 years ago. I noticed that you have the newest OS, that's great! My error message went away after installing the latest FIRMWARE. Just to be clear, firmware and OS are not the same. Get your K tech to check to see if your firmware needs an update.

As alland suggested, re-seat the ram is the first thing you should try. Sometimes they (ram chips) work themselves lose enough to loose connection intermittently. Also, temp changes, etc might cause it. Or there may be a slight bit of oxidation on the contacts. Re-seating the ram usually clears it up. If after that, it continues to happen, could be other issues. Maybe power related, possibly power supply. A battery backup with AVR (automatic voltage regulation) is recommended if the power is not the best in your area.

I recently got this message too

Have you got any new ideas about possible reasons of this problem ?

Haven't seen new useful ideas concerning this problem, but old ideas have been working so far. Those black screen errors are somewhat analogous to infamous "windows blue screen of death" (even when Kronos is a computer that runs on Linux). Provided that you have latest OS/Firmware on your Kronos and black screen errors happen accidentally (not systematically/after repeatable patterns) most probable reason is some small physical contact issue in or between components. Most likely on motherboard RAM seating as many have observed. Well, it traces back to the reason of poor component or build quality but there is very little one can do once you have Kronos out oF warranty or even under warranty when this black screen just happens when it happens.

ok

As you know the main problem is the reboot time of kronos.
(We need a backup keyboard for a keyboards that cost a lot of $$$$ as Kronos !)

I have a Kronos 2.
I don't even understand what are the last system/firmware available.
(is it compatible with Gold kronos ? )

I have currently system 3.1.2 but don't know where to find infos about current firmware installed on my kronos

Kronos 2 Subsystem Firmware updater with update instruction (that is different from OS updating) is on Korg webpage
https://www.korg.com/us/support/downloa ... /424/2536/
Updater itself should find out if Kronos needs updating or not.

The only issues observed here with Kronos, over several years of sterling service, were when two MIDI controllers were connected at the same time to the Kronos' USB-A ports, resulting in hung notes and unresponsiveness to the keyboard, and cured by disconnecting the USB devices and rebooting.

On the Kronos and Kronos X, if the Kronos sound engine icons are shown on screen during boot up, then the latest subsystem firmware is installed although the Kronos 2 may be different. If the boot up screen is relatively blank, apart from the progress bar, then an older version of firmware is installed.

In my case no midi controllers were connected to USB interfaces.
