CRT? Maybe adjust pots to brighten it up. Gentle whack on case improves display? Loose connection of cable or back of tube.
LED,LCD? Loose connection or failing component.

Don't know if it will help but I think you can adjust contrast in the handy page. It often takes a little bit for the backlight to warm up to full brigtness.

It could be a failed backlight. You'd still have a functional LCD, but not able to see the text or graphics.
I tried this.
Yes, I was able to adjust the contrast, and it is now better. However, it is nothing compared to the original display.
Next, I will check for loose connections.

What kind of backlight is in a Fanuc lcd?
Every failed backlight I've seen left the display so dark you had to shine a torch on it to be able to make anything out. OP didn't seem to imply it was that bad, although maybe it is?
If it's not that bad, and it's a CCFL backlight, there will also be an inverter board to power it. Failed inverters are pretty common, and it could possibly be still functioning but with a very low output?
