thanks for the concern guys (except for the comment about plugging it directly into the wall - and for the record, it wasn't).
just dreading the process of replacing/fixing this board and mad that i hadn't backed it up yet - only about 4 to 5 hours of total operation.....

I guess the bright side is now you have your problem out of the way, better now then three months from now with thousands of hours into it and a great need to have it this weekend etc...
Yea I know that didn't help.  |

Man, if that happens during a show, I'd be screwed. I hope we learn what the issue is.

same as any bit of kit - I would be in the same (sinking) boat if any keyboard died on stage.....

I'll let you know whatever I find out. I have to assume though that this is an isolated issue and nothing to be concerned about for the boards en masse.

Just as an example, a computer too has a fuse which cannot be changed easliy. More commonly, most appliance with switching PSU has fuses buried deep within the box. Reason: switching PSU's have all kind of protections built-in, so when the fuse blows, it usually (99% of the cases or so) is due to a component failure, to which a simple fuse replacement is not an appropriate solution and might even cause further damage if the root problem is not diligently explored and solved. The Kronos has a switching PSU, so you get the picture... If there would be a failure other than the PSU (i.e. causing overolad on the power supply or similar) then you'd see some lights briefly flashing upon switch on and then PSU protection would shut down. So, likely there were some problems with the PSU and the fuse blew to prevent fire. Hopefully your data will not be lost. |

This would be a main gigging board for me seeing 150+ shows a year

I apologize. However plugging something as sensitive as a keyboard directly into the wall can be very harmful. One spike can fry it. Especially in america where the power can really sucks. Some music specific places like rehearsal studios dont even have proper grounding. Just something to be careful with. I didnt mean to come off nasty. Hope your issue gets resolved

This is a myth. Surge-protectors and line conditioners hardly do anything. Ask any electrical engineer. |

No where near a myth.
If a triton (classic), for example, gets a small surge of electricity, it will start randomly thinking its turning the jog wheel.
if a triton extreme gets a surge, the first thing to go will be the tube.
having dirty power can greatly influence the functionality of your keyboards.. dont believe me? go ahead and sure your board. watch the screen flicker and never turn on again.
This is why ever since my triton started cycling patches i will ONLY plug it into protected power. never a problem since.

Heres a test i did while testing my triton out when i first got my Studio Monitors.
When my triton was plugged into the UPS, the signal that was sent to the monitors was fine, no pops or weird oscillations.
when it was plugged straight into the wall, it would be fine for a few seconds, then you could audibly hear some weird frequencies going through. Then I turned on the power amp in the room for the PA's (the room we rehearse in is underpowered) then i could start hearing tons of weird stuff coming out of the monitors. I made sure it wasnt just the monitors picking it up by unplugging the triton from the monitors and turning it off. sure enough all of that stuff going on went right through the triton only. you couldn't hear it when i unplugged it. About 5 minutes later is started thinking it was gettingthe jog wheel turned.
plugged back in the UPS and bam.. all better!
now tell me again that power fluctuations hurting an instrument is a myth please. My rig would be noisy and screwed up as hell if i didnt use a UPS (thanks to this forum for the idea btw)

true statement. happened to me during a show (I created a post about it in the Triton sub-forum about a year ago).
I use an APC power conditioner EVERYWHERE I play.

When it happened to me i searched and read your most Mchale. When i got the UPS i have NEVER EVER had a problem since.
After opening up the tritons time and time again, you will find that the jog wheel is actually one of the first things the power comes in contact with. WHich makes perfect sense with these issues.

I'm an electrical engineer. If the Kronos has a switching power supply there is really not a lot of concern unless you get a direct lightning strike, then all bets are off. 
A UPS power conditioner is not a bad idea though. Helps you to cruise through power outages. I have one on my Korg.
