My home is in the Canton cable, one opened on display, technical problems: set-top boxes can not receive a signal, ah, ah, ah, ah, help ah!!! How do you make it?
Ask where the smart card is. How can I not find it?This kind of paste is too irresponsible!My set-top boxes are free of charge. Contact the cable office first and check it out for you.Do not repair yourself, unauthorized repairs, man-made damage, cable stations can refuse free change.

Most of the items moved, so that the cable terminal box to the set-top box part of the antenna loose,
