Carlos demonstrates how to build a simple IR detector. Looks like it could be done for a dollar or two.
“An IR signal is “seen” by a reverse biased IR diode which produced an electrical signal according to the light intensity. This signal is then amplified trough a transistor and used to power an ordinary LED. This means that the LED will light up when the IR diodes receives some IR light (from a TV remote for instance).”

Finally, I way to find out if it’s a rogue TV or a TV-B-Gone being used to kill it…
