Half of 1602 LCD is white

I used a 1602 LCD with a shield (just four pines). It was fine, but after a fall down, it has a problem. When the number of characters exceeds 8 or 9, right half of the LCD become white (after about 100 ms).
What do you think?

To buy a new one. :frowning:

Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?

Can you please post a picture of your project?

Thanks..Tom... :slight_smile:
(Good to hear you got the stepper working)

Hi Tom!
the circuit is OK! I had checked it and worked! I guess some of the pin headers are damaged!
