I have a Sharp 27N-S50 and it is missing the cable (f-connector) connector on the back. I removed the cabinet and the shields where it enters the chassis, but don't see where I should connect the generic replacement part. I am an electronic technician (motorola) so I am comfortable with doing repairs. It appears to me the internal connection may have been a compression or some such fitment rather than being soldered. Any suggestions? Thanks,
After you remove the tuner from the main board and remove the 2 covers from the tuner, straighten the metal side of the tuner where the hole is for the F connector. If you look at the PC board inside the tuner, there is a small hole in the board directly under the hole in the metal for the F connector. Usually there is a small piece of the old F connector's center pin still soldered in that hole. If it is there, unsolder it and throw it away. The new F connector will be soldered in place over the hole in the side and a small jumper wire soldered from the center pin of the new F connector to the little hole in the PC board directly under it. Be careful when soldering on the tuner's PC board because the parts are extremely small and close together, and lost SM parts and solder bridges are possible. Be sure none of the coils in that area have been squashed over, which is what I usually see when the costomer sticks something in the hole left in the tuner. If the coils are squashed, you can straighten them with a small pair of tweezers or remove them and rewind then around the proper size drill bit. Let me know how you make out.

To be a little more clear, what I need to know is where on the tuner does the center pin of the female f connector connect to the tuner. Hope this clarifies things. Thanks again.
Thanks for help Mike, I finally got around to this project this past weekend and it is now up and running great!
Thanks Again,
