NOW I REMOVED LCD AND REPLACED WITH NEW. THIS TIME I USED SOME OTHER LCD (EXACTLY I DONT KNOW MAKE, IT IS HAVING CHIP ON BOARD, MADE IN CHINA AND YJ-162A AND PIN DESCRIPTION OF LCD) THIS LCD NOT WORKING IN THE PLACE OF FIRST ONE. I AM SURE THAT PIN CONNECTIONS ARE CORRECT WHILE INITIALIZING IT IS JUST GOING 16x2 MODE AND JUST BLANK DISPLAY. WHEN I AM TRYING TO DISPLAY SOME DATA IT IS NOT DISPLAYING ANY THING. JUST CURSOR IS BLINKING. AT FIRST LINE STARTING PLACE. PLEASE HELP ME IN THIS. THANKYOU IN ADVANCE. PADMANABHAM. |
