Hi Bob,
the simple 'Hello World' sketch normally outputs to the serial port
and so wouldn't show anything onthe green screen unless the
appropriate libraries have been included and the program extended to
include the output to the green screen.
So although it doesn't help you find the problem, your display may
not be defective.
Good luck,
Ian

Thank again for all the help!
I FINALLY got the complied RADUINO sketch to UPLOAD to my
NANO..? When plugged into my radio it TUNES the receiver but
there is still NO digital read out on the JHD162A green
screen.
I downloaded a simple "HELLO WORLD" sketch from ARDUINO
webpage and uploaded that sketch.? Still no reading on the
green screen.
I am concluding that my screen is bad..? Is this a reasonable
assumption?? ??
IS the JDH659a LCD Display module a direct replacement fit
for the JDH162a LCD display?

These are all warnings. They have
little to do with the running of the program. If it
works, OK. If not, you need another configuration as
already mentioned.
