LCD 1602A display issue [contrast potentiometer missing]

Cant be bothered to read past responses. Can anyone help to solve the display issue. (seen many having problems with this display - (maybe the manufaturers need to dig into this) all connections are fine, sketch fine, display only 16 boxes (blue light) NOT characters. i have no potentiometer. Have used other LCDs didn't have an issue. any short solution? thanks.

No information, can't be bothered.

okay thanks dont bother. if the display is working just the characters dont get displayed what more info is needed please.

Nor I.

Try one.

so pot is a must to solve this? is the connection to board just one way? i saw a complex connection.

Hello sunilvijaya479

Run a LCD tutorial to gain the knowledge.

i did a lot! and got to the stage of displaying blue boxes!! what i need is to go from there to characters. any specific tutorial you recommend? or can you write one specific to this problem? outlining reasons for this - as i said i used LCDs before - no issues at all. thx 4 ur response.
