Parallax Serial LCD w/Speaker Issues

-

i've acquire 1 of these lcds, , proceeded set up. when plugged in computer little intro along song, "parallax inc," etc etc, work. now, when upload sketch via arduino environment, nothing happens. i'm using test code available on parallax's site, , when compile no errors arise. i've tested arduino chip blink program , functions, know arduino chip works. 


any idea why sketches aren't  working lcd , intro text continues run?
