Hi AJ,
great to hear from you again.
Sorry to hear about your Korg.
My screen went too, it went black though. Unfortunately it was out of warranty & I had to replace it.
You did try re loading your os? just in case it was software related ?

I must admit I luved my PA800, my PA3x even moreso.

I swore to myself at the time I'd never buy another korg BUT, currently I've got 2. haahaa
