I used the search and couldn't find any topic about this problem, so i'll post it here.

I wired my LCD (CFAG12864B-TMI-V) up and connected it, but all it showed was this:

So i resoldered it completely, and got the same problem.
It also shows that screen when i only plug the power in. Now i'm sitting here with an LCD with only the +5, GND, Vcontrast & Vee connected, and it still gives the same screen.
Is it normal for an LCD to give this screen when it isn't connected or is my LCD broken? I certainly don't hope so :cry:

Usually results like this are seen when there is some problem with the wiring and timing. But as your display isn't even connected this shouldn't be the problem.

When I switch my display on it just stays blank and only shows things when driven by some program so I don't think what you see is normal. I've had pictures that resemble your's when I've written data with wrong timing.

If no other problem can be spotted I think your display might be defective.
