he returned it to me without power cable, so i bought a replacement one - it is 5v 3a one, since there was no 5v 2a available at my local electronics shop and the seller said that it won't be a problem using this one.
now after i connect the box to the tv i get no signal and the blue led light is blinking. Holding the reset button underneath won't do anything - the led keeps on blinking.
any ideas? Thank you
