its just swap the tuners, but theyre a tw@ to get out, unless you dont mind destroying the original cable tuner.
theres a row of about 15 pins, that are soldered on both sides, and through, the board, so with small snips, cut each leg of the original tuner, then one by one remove the legs while heating with a soldering iron, and using copper braid or some form of solder mop, get all of the original solder out of the holes
then put the new one in place, and flood each joint with enough solder to flow through the board to the other side, without burning it
