LCD Display problem

i can't seem second line on multi-line lcd's work. tried adafuit's modified liquidcrystal library 20x4 display. used serial lcd example sketch test the display , lcd smartie send serial data winamp display.

the problem first line shows data. on second line nothing appears. on 4 line displays, data suppose on second line show on fourth line instead. on 2 line display nothing shows on second line.

since happens both libraries, including 0017 library. i'm wondering if software bug in liquid crystal library or limitation of lcd smartie sending serial data.

has else had problem this? if so, le me know did correct , trouble shoot it.

regards

hi,

please check wirung of lcd. if ok, please post part of code drives lcd. maybe there's bug somewhere. not believe library not ok.
