The right half of the display is completely dark; can only read left side. Display was fine for 4 years. I have reset to original settings, but no correction on display.
I have the same problem. Any luck? Also, how did you reset to factory settings? Please let me know.

DISPLAY PROBLEM WITH SGX MODELS by: Anonymous
Regarding the factory reset - you hold down the highest key (c) as you hit the power button. Caution though - when you reset, you erase any saved settings and music saved on User Song 1-5.
And it does not correct the display problem. This info is found in the manual.
Regarding the vertical lines on display:
After reading the many comments regarding the display flaw that seems to exist on many SGX models, I talked to my husband (engineer, but not electronics) about replacing the display. He thought he might be able to replace the display. So, I decided to mess with the display a little; since it might need replacing anyway and it couldn't get any worse than it was. I turned power on and ran my finger over the display. You will see the movement within the display. At first, the lines on the right side lightened. Did the finger procedure again and the lines moved to the left side; and the right side was clear. Did it again and the entire display had vague lines, but was readable. Thought, OK I can live with this. Next time I turned power on, the display was completely cleared up. I'm guessing the pressure of my finger had some affect on the contacts. I know, it's not scientific, and probably not a permanent cure, but it worked. And for now, I am able to use the functions.

Yamaha Keyboard Display Problem by: Anonymous
Yeah this same thing happened to me... Frustration eventually overcame me and I decided to take the thing apart to figure out what was wrong with it. At first I couldn't find anything that was making this happen, until i wiggled the two ribbon connectors that run out of the lcd screen. I noticed that the picture would come in and out, I got it to work for a little while, however when I put the whole thing back together, my fix soon became usless. So you might get lucky by just wiggling those two ribbons if you dare, but I wouldnt recommend it, waste of time, and not even worth it. Yamaha should be ashamed of themselves.

Yamaha Keyboard Display problem by: Anonymous
I had the same display problem, resulting in my display eventually turning completely black. I reset the factory settings, but this did not correct the problem. I think someone had mentioned a contact in the display as possibly being a problem. I ran my finger across the display, adding light pressure - and my display came up. I have not had any problems since; this was a year ago. I know this isn't a technical solution, but I figured what could it hurt...and it worked.
