Kronos -- Shuts down after install of OS 2.1

[Bertotti]

Danatkorg has a good point I suggested this check only because of its ease and the off chance it might be an issue but like Dan says based on the OP's description it could very well be just a bad coincidence with the download, and the AC is somehow going out. I have seen crazier things then that happen on industrial equipment and controls.

This menu command may or may not be available, depending on the model of KRONOS being used. Default time, on models which support this feature, is 4 hours, and a message will appear at startup time noting the current setting (if enabled).

Which models support this feature?

I would return it but ask them to fix it! they will have to anyway.........

It could have been a firmware problem, since you stated that after the upgrade the sudden shutdowns have ceased.

For finding the Kronos powered off after a certain time of non usage... check the auto power off time. I struggled myself too before realizing what was the deal

There isn't a break at model names. It's simply in more recent production. This is the only change to those models, and is done to support an EU power saving initiative.

See the Parameter Guide (version E6 - new manuals for 2.1!), "Auto Power-Off Setting…" in the Global Page Menu Commands.

All of that said, I think this is a red herring for the case of the original poster, who describes: "At that point, I saw that my OS was at 2.0.6, so I decided to update to OS 2.1. I installed the update, and the keyboard immediately shut down, then tried to reboot. I shut it off, waited, then restarted. It would work for about five minutes, then shut down in the same manner. I tried this a couple more times with the same results -- shuts itself down, tries to reboot, shuts down in the middle of the reboot. "

While I can't say for certain, this sounds to me like a power problem - either in the AC system feeding into the KRONOS, or the KRONOS itself. I would be very surprised if it had anything to do with software. If this unit was purchased new, it should be under Korg warranty; I'd advise contacting your national Korg Distributor, e.g. Korg USA for USA residents, for more information (see the URL in my signature).

Thanks very much for all the responses. I had wondered about an auto-off, as well, because after installing the firmware update, the Kronos still shuts down, but always after a certain period of time. Typically around 15 minutes. It also APPEARS to be after a period of non-usage. I haven't had it shut down on me in the middle of playing since I installed the firmware update.

Dan, FYI ... I decided to take a chance and buy a B-stock. It's from an authorized Korg dealer (out of state), and a Korg customer service rep has researched my serial number and told me that I'm entitled to a full factory warranty. So that's a good thing.

I will try looking into the auto-shutoff.

If that doesn't work, does anybody know if there would be any value in starting from scratch? Just a full factory reset, then reinstall all the updates? Can I do that?

Again, thanks for all the great responses. Learned a lot here.

OK ... got home from work, where I could look into the auto-off. My Kronos does not have an auto-off function. Back to the drawing board.

Before I drive this thing 150 miles to the nearest service center, would there be any value in either ...

a) Re-installing 2.0.6 and seeing if the problem continues?
b) Starting over with a full factory reset?

Or is this likely a power supply issue?

Thanks.

Before driving it to a service center, definitely contact the support department of your national Korg Distributor (e.g. Korg USA for USA residents) - see the link in my signature.

as it didn't do it before 2.1 if I remember correctly I'd definitely look at rolling it back. If it DOESNT go away then you know its a hardware not a software OS issue. I just like to methodically go through all the options so it is easier for a tech to fix the real issue.

UPDATE

OK, I'm thinking this isn't a hardware issue.

I back-installed OS 2.0.6. The keyboard has run all weekend with no shutdowns. Color me puzzled (but happy the darned thing will stay on).

I'm going to try re-installing OS 2.1 and see what happens.

It's always possible that it's software, but I would be very, very, very surprised. My guess is still as above; note that power problems can be intermittent.
