[En-Nut-Discussion] Medianut 2.0d LCD Backlight Not Functional

Hi all.
My problem is I can not seem to get the Cathode, pin20 and Anode, pin19 to
work.
What is strange is RevD of the Schematic shows a odd configuration of 4
resistors, R22,R23,R53,R54.
I can not find R53 and R54 on my board but I do notice that R22 and R23 are
unstuffed.

Normal LCD commands and text are working and I have been using Medianut
successfully with several different LCD's.

My assumption is R53 and R54 do not exist so if I solder resistors in R22
and R23 nothing will short out and the LCD backlight command will work. Can
anyone confirm this?

Thank You
Tim C

Hardware:
Medianut 2.0d, Ethernut 3.0e.
