LCD compatibility

Ok so I tried Don's suggestion lcd.begin(6,2) and lcd.begin(8,2) both resulted in a blank display no characters displayed at all.
So now I have a LCD program that all it does is send to the display "LCD TEST" and it displays "LCD TE"
and the rest is missing "ST".
I have a second one of these displays and will try that next. It is possible I have a bad LCD which is very
disconcerting since they are new from Mouser!
