My screen works, but when I turn some knobs it just randomly goes blank, inverts text or flips upside down and wont go back to normal.
I upgraded to 2.0 software but still have the sames issues.
Has anyone else had this problem??
lcd screen is going crazy???

I presume that you are talking about a Radias and not an R3?
Anyway... I have no experience repairing either of these units but as a profession, I work with metrology test equipment. This is an educated guess at best but it sounds like you have a faulty display driver or a problem in the display driver path. This is not a display driver like you would have in a PC, it isn't software; it's hardware. This may be due to a a chip being hit with ESD (electrostatic discharge) during the manufacturing process, or perhaps a cold solder joint.
In any event, it is worth giving Korg tech support a call. They probably have a flat-rate repair cost for hardware malfunctions.
