Replacement LCD screen for KN2000

Hello Technics world, I have recently purchased a KN2000 from a guy and at the time of purchased i of course played with it to test it out and make sure that everything was functioning correct. So everything was working fine minus two keys and went ahead and purchased the keyboard. I figured the two keys not working was due to build up of dust. So I opened up the keyboard and cleaned every single key as well and when I put it back together I turned on and those two keys were working fine, but now I have an even BIGGER problem.... My LCD screen isn't working properly, it turns on, lights up and is just in a white screen. If I could get some information as to fixing it or even info on where to buy and replacing the screen I would greatly appreciate it. I'd really like to explore this nice keyboard, heard soo many great things about it and would like to play it soon! Thanks
