Display is not working properly. I have checked my connection several times but it's still not working. Is there any method to check whether LCD board is good or not?

Answers:
Use the following connection to check whether your LCD is working or not.
1. Connect pins 2 & 15 of LCD (i.e. Vcc & LEDA) to the +5V pin of the Arduino.
2. Connect pins 3 & 16 of LCD (i.e. Vee & LEDK) to the GND pin of the Arduino.
If the lower line of your LCD screen will be brightened then your LCD screen is working.
If both the lines of your LCD screens are brightened then your LCD is not working.
