Can you upload the simple blink sketch found in the IDE examples to see if your pin 13 flashes (on board L led) ?

Hi jawad102480,
Your wiring - thanks for the pictures - is OK. Does the LCD light up? The display might be corrupted.
Then run an i2c scanner to see whether the electronics of the i2c backpack on your display is responding. No i2c address - no show and no response on Serial Monitor.
