EDIT: NO I AM NOT AN IDIOT. The reply to which this message relates was posted on November 19, 2013 and then removed after I posted this. I usually include a quote to avoid situations like this but I forgot to do that this time.
You have resurrected another old thread.
I have the same advice for you today as I did yesterday: --> ywRobot I2C LCD problem / solution - #12 by floresta - Displays - Arduino Forum
You should use the old threads for reference, but start a new one for your problem.
