LCD Keybad Shield Has Power, but Can't display text

[ham_man]

So I plugged it in and was running the hello world example. I already turned the potentiometer but just nothing showed up. The pins are connected properly.
I did change the the pins it read to the ones that my keypad used. It was

LiquidCrystal lcd(8, 9, 4, 5, 6, 7);

Here's the full code:

#include <LiquidCrystal.h>

const int rs = 8, en = 9, d4 = 4, d5 = 5, d6 = 6, d7 = 7;
LiquidCrystal lcd(8, 9, 4, 5, 6, 7);

void setup() {
lcd.begin(16, 2); // Initialize display size
lcd.clear(); // Clear the display
lcd.setCursor(0, 0); // Move to the first position
lcd.print("LCD TEST OK"); // Simple text
}

void loop() {
// Nothing needed in loop — text should stay on the screen
}

Please post the code you are using

Since I don't see a single row of boxes, my first guess would be that you're communicating just fine to the display and the contrast has been turned down. That looks like a multi turn pot so you might have to turn it quite a few times before getting the contrast into the visible range.
