Can somebody post the PA800 Diagnostic Menu Command


The details are highly confidential and have only ever been released to engineers under Non Disclosure Agreements, who work closely with Korg in the design process. If anyone tries to tell people about it on the forum then a breach of an NDA has occurred and whoever did it could be sued by Korg. The person posting those details could have their account on the forum suspended.

Please understand that there are very good reasons why Korg want to keep those details confidential. The functions were designed for use in the factory when the keyboards are manufactured. Two of the functions can completely wipe the internal SSD and the boot EPROM rendering the complete keyboard unusable. One of the circuit boards would have to be returned to a factory for the chips to be re-initialized using specialist hardware plugged directly into the CPU board. The necessary hardware to re-initialize the SSD and Boot EPROM is not even available to Korg service centers.

If you are someone who has discovered the way to access the system diagnostic menus, then there is a high risk you will completely trash your Pa2x/ Pa800 etc, turning it into a "brick" that will no longer be capable of reloading the OS or factory data. Korg representatives have said to us several times that damage caused in this way is NOT covered by warranty. If two of the functions in the system diagnostics menus are used, then to get the keyboard working again, service centers will have to replace the complete "main board". This is the board which contains the SSD and boot ROM chips. You are looking at a repair cost of over $800 plus shipping.

Factory reset korg pa1x ?


To factory rest on Korg pa1x you should take few steps and as a warning i have to say you will lose all your existing setting and data.

First download the operating system version 3:01 into four floppy disks. you can find it for mac and PC versions.go to http://www.korgpa.com/support/discontinued-products/korg-pa1x-pa1x-pro.html

Second: if your Pa1x has Hard drive transfer the factory resource file from the above link into hard drive.otherwise you need to copy factory resources to FDDs again.

Third: turn off the Keyabord and insert the FDD1 into floppy drive. once you turn the keyabord if you press intro instead of OK it will wipe all the OS and setting on your keyboard and then start installing fresh Operating system.

Fourth: turn off and on the keyboard. then go to this and go to utiliy and find your HDD and load the factory resource. I mentioned if you don't have hard drive then go to FDD and insert the FDDs for factory resources and load them one by one. then turn off and on the keyabord.

All done.

I can`t load the OS in my KORG PA 80. No way to make it work. I think than the problem is the mother board.


Have you tried it with batteries? Are you sure the power supply is working correctly? It should not need the OS to operate as a keyboard disconnected from the computer.

The cable connection is just a MIDI cable that uses opto-isolators so the 2 items are electrically isolated from each other. The software driver for the Korg should load without problem. The Korg program itself may be looking for inputs that are not there when the keyboard is off and the program itself reaches a stop command.

If the PA80 will not work on just the power supply- the power supply can be the fault- it has an internal fuse. Finding a similar supply with the same coaxial plug wired the same polarity is the way to test it if the battery option is not available.

Hi i got the korg pa50sd when i swith it on it shows me korg pa50sd boot loading files then this goes off, still the light on display is on but blank display with nothing on it ,. i was trying to find any...


NOT a fuse... thaat person knows nothing. There is something wrong for sure. Check if one of the buttons or keys MIGHT be stuck down (depressed). Sometimes the units check that all the control buttons are up and they don't really tell you why they fail to start. Beyond this a repair shop is in order.

The unit will not switch on from the remote or the button which only glows orange and will not turn blue. What can be done?


Take it to a repair shop, the orange glow signals a fault in the power source of the tv and it must be fixed by a pro.

Every 3rd key is "touch-insensitive"


It's a mechanic problem, the plastic &/or the circuit under the keyboard keys should be cleaned and/or changed.

Macbook Pro goes from gray apple screen to black


Try booting into single user mode by pressing Command+S while booting. You should then be at a prompt. Type in:
fsck -f
and press Return. Let it run and see if it corrects any filesystem issues, then reboot when it's done.

Korg triton Touchview screen not working properly


The Korg Triton touchscreen has two main parts - The LCD screen and the touch overlay. Between the two is a type of gasket. It is really just an adhesive, but it does help keep out moisture and dust. If you were to remove the screen, you could separate the two parts, clean it and use double-face tape or glue to reattach. You can also get a replacement LCD screen, touch overlay or touch-LCD assembly from a number of places on the internet. They are not cheap, unless you purchase a generic touch overlay or LCD and retrofit.
As for repair in your area... try contacting Korg at http://www.korg.com and look for authorized repair centers.
