How to fix dead LCD backlight and change CCFL to LED on display panels 

How to change dead LCD panel CCFL backlight to LED.
This was fixed on a Yamaha PSR-3000 but I have done this many times on several keyboards & other old CCFL and electroluminescent displays. The music played at the end of the video is Yamaha's built in Demo from the Yamaha PSR-3000 keyboard.
