Hello,

i`m in the last fase of a big project but now my glcd begins to fail or something.

I`m missing a horizontal line in de display.
What can this be? Is my lcd broken?

I`m using the following:
18F452
SED1335 320x240 LCD
85 euro is alot of money.... So i hope its not broken.

Greets,
Gert

Looks more like a row driver problem to me ,, maybe a defective unit

did you checked if you have correctly disabled analog converters on pins driving the display?
