reg tsop interfacing

Hi,
I am using 89v51rd2 controller,,i wanted to blink an led on board using tsop sm0038 ir reciever,the code which i used for this is

sbit TSOPSEN= P3^4; //Input from TSOP sensor
sbit LED = P0^4; //Output display from TSOP sensor

void main()
{ while (1) { LED=0; if(TSOPSEN == 1) { LED=1; } }
} but wen i dumped the code and pressed the remote,the led is not blinking
