Why is LCD not powering up on first power up

i finished building the kit and double checked the electrical connections. When i powered it up for the first time the LCD did not power up. I turned it off and rechecked all my connections. I read another question on this forum and it suggested that i switch the LCD connections, which i did. This time the backlight for the LCD came on but no data on the screen. When i push the button it beeps. I have now checked my connections many times and completely unplugged and replugged all the connections but still nothing on the LCD Screen.

Answer this question I have this problem too

Is this a good question?

I had the same issue . Make sure you plugged the flat connection with the red part heading upwards.

It did work for me...

Thank you. The instructions were incorrect as to the Rambo ribbon connections both in that the red strip didn't go down and pin on the Rambo board was incorrect.
