IR remote trouble

Using Arduino General Electronics
1

i created two independent circuits for receiver and transmitter. Both are arduino uno, and uploaded this code to the arduino.

fortunately both works, the transmitter sends the code and receives to the other end. But when I used it to command to turn off (38863BD2) my tv which i decoded earlier, nothing happens. Tried multiple times

#include <IRremote.h>

const int RECV_PIN = 6;
IRsend irsend;
IRrecv irrecv(RECV_PIN);
decode_results results;
int sr = 9;
int x=LOW;
int i =0;

void setup()
{
Serial.begin(9600);
pinMode(sr, INPUT);
irrecv.enableIRIn(); 
irrecv.blink13(true);
}

void loop() {
x= digitalRead(sr);  

// for sending
if (x == HIGH){
  Serial.print("send");
for (int i = 0; i < 3; i++) {
      irsend.sendNEC(0x38863BD2, 32);
      delay(20);}}

// for receiving
 if (irrecv.decode(&results)) {
    if (results.decode_type == NEC) {
      Serial.print("NEC ");
    } else if (results.decode_type == SONY) {
      Serial.print("SONY ");
    } else if (results.decode_type == RC5) {
      Serial.print("RC5 ");
    } else if (results.decode_type == RC6) {
      Serial.print("RC6 ");
    } else if (results.decode_type == UNKNOWN) {
      Serial.print("UNKNOWN ");
    }
    Serial.print("  ");
    Serial.print(results.value, HEX);
    Serial.print("  ");
    Serial.println(results.bits);
    irrecv.resume();
    }}

Please look at the following site for NEC protocol.

The data you are sending out does not conform and is probably rejected by your TV.
0x38863BD2 = binary 00111000 10000110 00111011 11010010, byte 2 is not an inverted image of byte one, same for bytes 3 & 4.

Shouldn't there be a current limiting resistor in series with the IR LED?
