Yes. It is a fluorescent tube. It has to be from the OEM though.. It usually comes as a diver board and tube assy.

It could be the light, or it could be the inverter that powers the backlight. Try asking this guy: http://www.mikebarden.com/technics-electronic-digital-kn-pr-px-piano-keyboard-ensemble-repairs/

get the part number on the LCD board itself which is mostly written on the corner and contact its service site with the number.

Only by replacing the screen.

I don't see why Technics couldn't replace or fix it.

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.

Try formatting a fresh disk in the KN2000. If it doesn't work, something in the drive has gone bad. First thing would be to CAREFULLY clean the heads using 91% isoprophyl alcohol.

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