Looks like the OP will need a new LCD and backpack. Good work @groundFungus for spotting the error.
Yuppers, an image right after post#2 would have saved a whole lot of...
@groundFungus You were right, just finished soldering and it works. Thank you so much and sorry for the waste of time

Sorry bothering again. But I have another problem lol. The backlight turned ON but the LCD doesn't show any text. Same connections, same code.
Did you try the contrast pot? Do the blocks change when you do adjust the contrast pot?
Post clear photos of the soldering. Both sides. Maybe we can see something that you are missing.

Sorry for the late reply, the forum didn't let me answer.
The blocks don't appear now, it just the empty display. (Backlight ON)
And yes, I tried the pot and doesn´t change.

I think they are good. And no, those aren´t tin particles its just dirt and leftovers from scratching lol
Hello
I guess the soldering isn´t well done.
Have a nice day and enjoy coding in C++.
Really, buy a new display with the backpack attached.
