I need some help,i have just bought a JHD162A LCD,and have tried interfacing it with arduino but all in vain,tried every possible thing but cant get it to display anything,I connected it exactly like this and ran the hello world code,but am just getting the backlights lighting,no display,i have tried grounding pin 5 of the LCD,still nothing,please help me get out of this state of quagmire,i have been doing the same circuit since yeaterday,at first i thought i had made a mistake in the connection,then i re-did everything but the same.I even thought i bought a faulty LCD,then went back and bought a new one but all the same

Try using a potentiometer on pin 3 instead of the 10K resistor.
