Need more info.... using line out or does it have built in speakers, make sure if it uses an ac power adapter that it is the correct one (AC vs DC output and voltage\amp rating makes a difference). Is it moved often, was anything dropped or spilled on it, etc? Age... model number and you say organ I'm guessing it's actually an electronic keyboard?

i need to replace screen display of my KN 2000 Technics K board with a new one because it has become unclear have a lot of lines appear where can i find ,plz help me to replace.

IF the normal screen had a blue background, POSSIBLY the contrast setting got moved to the end of range making the characters invisible.

The contrast control MAY be called several names including CONTRAST, VIEWING ANGLE, etc... Refer to your user manual.

You might need a version of Cakewalk to do this, but it is available.

First thing is to Isolate the keyboard and then take out the Hard Drive and restart the keyboard. If that doesn't work then that's the first problem eliminated. You can do a Factory Reset on the keyboard. I'm not too sure on this keyboard but mostly it's Turn on the keyboard and simultaniously hold a certain button(s) or Key(s) [normally at the top end]. This info will be in the Manual.You could look at the troubleshooting page in the Manual also. Other than that at this time I can't help any further.......Good luck!
