Problem initializing LCD

Other Hardware Displays
1

I use the 1602 and the 2004 displays, and they work fine (serial with LiquidCrytal I2C), as long as I use Arduino 1.0.5.
Now I tried Arduino 1.6.1 (and 1.6.0 and 1.5.8 and 1.6.2), but i don't see anything on the displays, with exactly the same sketch !! And no alarms or problems are given.
Can anybody help me?

I forgot to say I have the problem with UNO and with NANO !!

Sketch ?

thank you for your reaction,
but ALL sketches don't work: even not the included "Hello World"
the following sketch works with the versions Arduino until 1.5.5 but does not work any more with versions with a higher number, like 1.6.1 or 1.6.2

#include <Wire.h>
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27,16,2); // set the LCD address to 0x27 for a 16 chars and 2 line display

void setup()
{
lcd.init(); // initialize the lcd

// Print a message to the LCD.
lcd.backlight();
lcd.print("Hello, world!");
}

void loop()
{
}

Are you using the F Malpartida library?
Maybe its time to update to the new LCD Library !

I tried, but I came to the conclusion: up to version 1.5.5 everything is OK.
versions with a higher number don't work.

so i stick to the 1.5.5, it works, and it is good enough for me

thank you for your reaction
