hi,
'm using a jhd 162A blue 16x2 display. when i display a msg in english it is displaying it in some random characters, whereas the numbers are shown correctly. when i change the lcd and put a jhd 162a green/yellow display the english characters are shown correctly. where is the problem? should the blue lcd be programmed differently?

I suggest you do 1) 2) and 3) in this thread:

Could be solder job or could be back light.

I doubt it was a manufacturer's defect.  It was more likely a purchasers mistake.
