Problem with 2x16 LCD connection to power supply

[auto_mitch]

Hi everyone!
I have an LCD 2x16. It has 16 pins. I read the data sheet and i connected it to power supply +5Vdc. The first pin is connected to Gnd and the second pin is connected to +5Vdc.
When i first connected the lcd to power supply i saw the fist line full of black pixels. when i connected again it didnt work but only the backlight could u please give a reason for what could have caused this?
thanx

Vast majority of these text LCD uses HD44780 or compatible chip. You will not see much unless you initialize the LCD module.

Do a web search for HD44780 or take a look at following two sites:
