Hi, please specify your problem, info like "with no succes" is not a good description and show your code (use code tags). J.

Assuming that you are using my TextLCD lib with I2C support, the common issues are that you have the wrong I2C adapter selected or the wrong I2C address for the adapter. Other issues might be missing I2C pull-up resistors. See here for some hints and solutions.
