This is my first post, before posting i searched the forum for someone with a similar problem as mine. But didn’t really find a definitive answer, so here goes.
I have (or had) a good working LCD display. For a project, I have a PCB with a header where the LCD is connected to (image 1). The header is numbered like this;
I wasn’t paying that much attention when i connected it, and did it as follow (image 2).
After doing this I got some sort of squares displayed (image 3).
Then i noticed the wiring was wrong, wired it the correct way and still got the same results.
I then unplugged it from the PCB, and plugged it to a breadboard to test the simple “Hello world” program. But i still get the same blocks as in image 3. Also if i touch the back of the LCD while it’s displaying these blocks, the image fades and comes back.
So now I wonder, did I kill the LCD when i plugged it the wrong way? actually it’s not really dead yet, more like brain dead but still…
