Hi Guys, am looking for some help with a LCD. when I boot it up I get the back light and but it looks like I have some dead cells in my screen as some sections of the text is not displayed is this possible? or could this be a wiring issue?
Thanks
When I turn the contrast right up I get 16 black squares on the top row but when I turn it contrast down and try and display text on my LCD there is missing sections in the text.
Can this be a wiring problem?
This may be an instance of something others have encountered.
To explain badly...
Suppose you wanted....
12345
ABCDE
... and sent them as two 5 character strings.
Some LCDs need careful handling. They DO what they are SUPPOSED to do... but that isn't always what a user THOUGHT it might be supposed to do. For instance, the display might not "understand" whatever you put in to say "and on the second line...". and would then display...

Of course, if it were that simple, you would have spotted it. But look to see if perhaps your LCD is "rearranging" the things you sent.
There are many threads on THIS sort of thing. I hope that is what is going on for you, not some dead character cells, or something more tedious.
To save others saying it...
Tell us EXACTLY which LCD module, how it is connected, and maybe even post your code.
For not very much $ ou can just go around a lot of these issues....
(If that refers to SoftwareSerial, replace all such references with "NewSoftSerial")
Thanks for the reply
I folded this example Arduino Tutorial - connecting a parallel LCD
and am running the hello world example with the changes from the example
and this is the photos of the output from my lcd
I dont know what model my LCD is.
Could this be a wiring problem?
I doubt that it is a wiring problem since your sketch is obviously running correctly. In this case I would suspect that there is a problem with the hardware on your LCD board.

Thanks For that I thought that awell looks like i will have to order another LCD and try again.
