Problem with graphic LCD CFAG192128A-TMI-TZ


New member

I'm trying with graphic LCD CFAG192128A-TMI-TZ. It was working well, but suddenly it started working bad using the same source code.

I write the first line (line 0) and It shows the same information in all even lines. And I write the second line (line 1) and It shows the same information in all odd lines. If I write other lines It doesn't show anything.

The attached image shows the first line written (0, 0) with hexa FF, and second line with (1, 1).

I appreciate any help. Thanks in advance.

I am not sure what has happened. Please look carefully for shorts. Failing that the LCD probably got damaged somehow.
