atmega328 + LCD 16x2 - nothing shows in void loop

Ok, I changed some lines in my sketch and now it looks like this:

#include <LiquidCrystal.h>
#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>
#include <RF24_config.h>

int led_sensor = 8;
int led_error = 6;
int sensor[1];

RF24 radio(9,10);

const uint64_t pipe = 0xE8E8F0F0E1LL;

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup()
{
  Serial.begin(9600);
  
  lcd.begin(16, 2);
  
  lcd.setCursor(0, 0);
  lcd.print("Ready");
  
  radio.begin();
  
  radio.openReadingPipe(1,pipe);
  radio.startListening();
  
  pinMode(led_sensor, OUTPUT);
  pinMode(led_error, OUTPUT);
}
void loop()
{
  if (radio.available())
 {
   bool done = false;
   
   while (!done)
   {
     done = radio.read(sensor, sizeof(sensor));
     
     Serial.println(sensor[0]);
     delay(20);

     if (sensor[0] > 600)
       {
         digitalWrite(led_error, LOW);
         digitalWrite(led_sensor, LOW);
         lcd.clear();
         lcd.setCursor(0, 1);
         lcd.print("Sleep");
       }
       else
       {
         digitalWrite(led_error, LOW);
         digitalWrite(led_sensor, HIGH);
         lcd.clear();
         lcd.setCursor(0, 1);
         lcd.print("Working");
       }
   }
 }
 else
 {
   lcd.clear();
   lcd.setCursor(0, 1);
   lcd.print("Radio off");
   Serial.println("Radio off");
   digitalWrite(led_error, HIGH);
   digitalWrite(led_sensor, LOW);
   delay(1000);
 }
}

Unfortunetly it doesn't work. On the display is only word "ready".

I tried to program the example "Hello world!" and it works, but my sketch not. Is still something wrong in my code?
