You were moving your TV but forgot to remove the cable.
Suddenly you get to the end of the coax's length and keep on going. Out comes the "F" connector from the tuner. What do you do now?.
If you were lucky you can install a new "F" connector with some work. If you were not lucky you will have to install a new tuner. If you do not have the skills necessary to install the "F" connector (it is tedious), you may want to opt for a new tuner which should not be that expensive anyway.
If you have good soldering skills and can work on small items you may be able to do this. It requires removing the lower back of the unit, removing the board that the tuner is mounted to.
Depending on the type of TV, Direct view, LCD flatscreen or projector there are various ways the board could be removed.
Usually the tuner is on the small signal board. To remove this board you will need to take out all the screws around the perimeter so the board can be lifted out.
Some units also have plastic fasteners which need to be popped loose. They are pushed up through the board and help to stabilize it. The hold down method should be obvious if you study the board.
Once the board is removed turn it over to the solder side and unsolder the tuner and remove it from the board. Next you will need to pry the sides off the tuner.
Mark them left and right or in some method so you can reinstall them on the proper side. They generally have grounding tabs which need to be located in a particular space.
Once you can see the solder side of the board check it for cracks or damage and if possible remove the old connector wire from the "F" connector.
If the board is damaged you may have to replace the tuner. They are available at http://www.encompass.com
and usually are under $50 US.
Order a new one, reinstall it and reassemble the unit and your unit should be ready to operate.
If the board is not damaged you will need a new "F" connector for PC board mounting.

When you get the part you will have to fit it to the unit and solder it into place. This should be obvious. I always solder the connector to the tuner case the entire circumference of the connector and have never had any repeat repairs. To do the soldering on that you will need a 120/140 watt soldering gun. They are available at http://www.mcmelectronics.com
If the board has no hidden cracks it should work when reassembled. Reassemble the tuner, install in the board, reassemble the TV and you should be operational.
