Interesting question. I would say you need to contact "KORG support" for this. Even if you can get the part, replacing it does requires skills.

Hi i've had the same problem.... twice Sad , no backlight but display is readable...

It's not the ccfl lamp, but the inverter that powers the lamp.....

First time i fixed the inverter with new transistors , this fix did the job for about 3 years....

so last week again no backlight... i now replaced the korg inverter with a replacemnt inverter normaly used in laptop displays..... (lost my faith in de korg inverter)

Replacing the inverterboard is plug & play... you just need to open the keyboard and then remove the screws from the display to get acces tot the inverter ... pull off the 2 connectors from the old inverter and plug them in to the new replacement inverter ......

any questions please ask

gr,

Snikhaas

u done need any inverter or ccfl lamp, its very simple to change backlight with few chinese LED-s, and it will cost u less than one beer Laughing

and believe me, its much better light than ordinary ccfl..... i did it on one triton extreme, on pa50, 80 and few more keyboards......
