Little update on my Korg Karma vertical lines. During this last week since I bought this keyboard, I noticed that the vertical lines seemed to be gradually disappearing. I began to use the contrast adjustment to turn the display all the way “black,” and then all the way “white.” I then left the contrast all the way up for an hour, so that the screen was “black.” I bought this synth for a very low price, with the belief/hunch that I could find a way to fix the issue. I get the feeling that this keyboard has just been sitting around turned off for many years, and that the liquid in the display just needed some help getting started. Now, we’ll just have to see if it lasts. Here is a before and after photo.
