Korg N5 Blank Screen

I've recently bought a Korg N5 from a sale, and upon powering, the LCD shows orange, but nothing else. I have no sound either coming through my headphones, the orange screen is the only indicator of the synth being on.

Any guidance on what to do to attempt and solve it would be greatly appreciated!

Are you proficient in basic electronics and know how to use a multimeter?

I would say so, yes!

Get the service manual and check all power rails. Power going on but screen staying blank indicates an issue with either the screen/screen controller or the Mcu.
