I just unplugged the power cord from the power bar to add some things and when i plugged it back in, these lights would flash on the digital box and it will not work. this has been happening for a couple of days now. I've tried taking all the wires including coaxial out and waiting and then plugged them back in to no avail. It seems to be almost connecting to my tv but cutting out, so maybe its a hardware problem with the power or something up with the box. Please help!
