I tried this on 3 different brands of TVs (Magnavox, Sony, Sylvania) and none of the programming methods worked. Tried the code method, the channel method and the automatic method. The LEDs worked as stated in the instructions. I'm not sure if I received a faulty item or if it just doesn't work as promised and works with 99% of the brands mentioned.
