LCD display pinout for Solomon 4 row

[Veketti]

Hello,

I had one 4 line lcd display laying around and planned to use it on my PIC projects. Problem is that I don't have any datasheet and cant find it by google search. Tried it if it were HD44780 compatible and used the same pinout but nothing on display. I even tried to supply +5V on pin 2 from left, gnd on 1st and +5V on 3rd for contrast and nothing on display. Anyone have datasheet or any idea to test if this is actually working or not?


Thank you in advance
