Without your schematic and a link to the 1738 device datasheet - no.

THINK. This is an electronics forum. "does not work" is not information, it is whining. Schematic, photo of your device, a description of what the circuit is supposed to do - something, anything that resembles actual information would be very helpful.

I assume you're using the Tsop1738 chip, some user examples here..
