I have an old, but works beautifully RCA Home Theatre TV. My problem is that the tuner ( where the F1 connector goes in) seems to cause the picture to distort wildly at a moments notice until I push the TV or giggle the cable to tuner connection. What do you think? Do I need a new tuner? is the soldering gone? or is the TV done??
Hate to part with it, beautiful picture, when working - RCA Home Theatre - 35" - (No PIP)

On most sets the tuner has to be removed for this to be done-a new fitting or a new tuner can be installed.
If the set has the standard RCA audio and video jacks for input you can hook a cable box or even an old VCR to those and BYPASS the coax fitting--hook up to those inputs--select them on the set and leave set on that input and change channels with the box or VCR.
Much cheaper than replacing the fitting and gives a better picture.
This happens all the time. It just might be fixable. This connector is known as the "f" connector or female coaxal connector. Most average electronics technician can fix them. This connector is attached to a component called the tuner. The tuner is what takes the signal and selects the channel the tv recieves. To replace the connector it means removeing the cuircit board that the tuner is on and then removeing the tunner, disasembling the tuner. Now until you find a good tech, there is another option... take an vcr and use the rca inputs on set. essitally tunning the set through the vcr. Now you will have to change channels through the vcr. but it will work. also there is a chance that the tuner might be damaged. just depends on the damage that occured when the connector was broke off..,let me know if you need any more help
There must be a fault in the screening of the internal wiring to the scart outlet in the home theatre system. I simply changed the way the player was connected to the TV and the interference disappeared:-
1.) I used the RCA video outlet instead of the scart lead. Picture quality was not compromised. FYI the Panasonic Plasma TV I have has only RGB video input sockets at the back, so I used a scart to RCA adaptor to overcome this problem of connecting old technology to new.
2.) The surround sound when playing DVDs is generated directly from the home theatre system so there was no need to connect the audio from the home theatre system to the TV
3.) I used a pair of RCA leads to connect the "audio out" from the TV to the "audio in"on the home theatre system to provide the option of TV sound through the home theatre system.
you need the red and white audio cable hooked into the AUDIO OUT connectors on the tv and the other end of the red and white cables into the AUDIO IN in tv to the media center (main Bose unit).....If your tv does not provide AUDIO OUT connectors, you cannot connect the tv audio to the 3-2-1 system. Continue using your tv speakers for sound.
If you are decent with soldering iron you can repair it yourself. Remove the back, and remove the signal board from the unit. Unsolder the Tuner from the board( If I've lost you already, call a TV shop for repair) Remove the shields on the tuner and inspect for damage to the tuner itself. If the board is in good shape, replace the RF connector with RCA # 215543. you'l have to unsolder the old ends connector ( the wire thats still there broken ) from the board, then attach the new end, and solder to the board. Then using high heat, solder the Connector to the tuner housing. Replace tuner on board, hook everything back up, and you should be in business.
Replacing the "F" connector is usually all that's needed unless the tuner board is cracked. You could remove the tuner - send it in for repair and re-install it... It would clearly save a few bucks!
Any shop should be able to do that one easy enough... Around here we charge $40.00 including the part to replace the "F" connector and there are shops that charge even less...
