Hey I am very new to electronics I am trying to get my LCD to work with Arduino but it's not working. I want to learn how to debug my lcd to check where the probelm is. I have tried many forums but nothing helped.
Please dont ask me to check the connection and circuit diagram. I have done it many times. I have also replaced the display and Arduino nothing changed. My circuit diagram and code is same as given here
Please help. My display shows only plain white screen all the time
