Hello,
![Sanni Cart reader](https://user-images.githubusercontent.com/119793366/222981289-2fe4395a-33d8-433c-bf0e-90dfc7820bc8.jpg)
I have just build Card Reader Version 3 few minutes ago. I have problem with screen that displays on OLED. It looks like not all horizontal lines are drawn. The bottom of the screen is not affected. Everything is fine there. I have shown it in the photo. I resoldered the connections from both sides of the OLED PCB again, but it didn't change anything. Is the screen damaged and needs to be replaced? Please help.
