Just finished assembling a unit from the second batch (November).
A little ghosting or blurring effect can be noticed when changing from one to other parameter (specially when it has to redraw the whole screen). The more I tweak the knobs, the more blurred and messy it gets. A couple of seconds after changing a parameter, the screen is completely clean, though.
Finetune the Contrast Pot, its a matter of a fraction of a turn… I have my studio in the basement, so its sometimes a bit colder and the problem occurs here when Shurthi is at lower temperatures and disappears when the machine gets warm.
This doesn’t sound right… Has the LCD been exposed to low temperatures or moisture?
I’ve seen it too when my LCD contrast wasn’t tweaked quite right.
I have the blue LCD.
