Officejet Pro 8600 control panel is dim

[Alison20]

The control panel is almost impossible to read.  It is very bright and washed out - the words are not visible.  The background was previously black but now it is white and words are blurry.  The printer works just fine, but the control panel is nearly unable to be used.  The warranty has expired.  I have unplugged power source from printer and then from wall.  Waited 1 minute and plugged it back in.  I can't see the settings preferences to change the brightness.
