Yamaha PSR 3000 Display problem

My Yamaha PSR 3000 display has been developing a stripe or a partial next page showing on the right side of the screen. It covers up some 10 percent of the intended page .

Thus far I can still do a gig but, I'm afraid of things going really bad during a performance. I usually carry an old spare synth around just in case.

I'm wondering if it's the display unit or , perhaps, a video circuit within the instrument's Mother Board.

Any thoughts?
