Try putting some pressure on the black trim that surrounds your LCD glass and see if this condition changes. You could have a loose connection between the LCD display and it's pc board.
well look at that! it sure did change the condions.. by slightly give some pressure on the frame it has been solved, how would i get this pressure on the frame forever? or do i always have to live with the fact that its broken?
You have a problem that is most likely related to one or more of the six connections between your Arduino and your LCD module.
i was almost 100% sure that i connected everything according to the connections mentiond on my 1st post, do you realy think my problem is that i have hooked up something wrongly?
anyway ill desollder everything and resolder everything with a little less solder on each pin. im still not realy good at soldering but ill try (any tips are welcome)
i will let you know when im done and what the results are.
