    unable to jam TV remote

    My TV remote sends a 38KHz frequency IR radiation to the TSOP1738 receiver inside my TV.
    To jam that wave, I thought i will send infra red radiation from a LED continuously so that it may interrupt the signal that was sent by the tv remote. It didn't work, why?

    Because DC and continuously 38 kHz modulated light are supressed by the receiver.

    It's all in the TSOP1738 datasheet.
