My coax input on a '93 GE 27 inch TV has has picture failure. I deduced it was the coax connection and bungee corded for pressure with some success; but eventually the picture goes, except for the weather channel and a few locals.
I have not taken the back off, yet. What do you suggest?

Yes. A similar workaround would be to run the aerial signal via a video recorder connected to the A/V inputs and change channels on the video instead.

If the GE has audio/video inputs perhaps a wireless audio/video transmitter/receiver setup from the programming source be utilized to avoid using the coax input.

I'm assuming you've already checked that the plug on the end of your aerial cable is correctly fitted and has no short between braid and the centre pin.

It's likely to be just a dry joint to the co-ax socket centre pin inside the tuner. As a result of mechanical stress, you often get hairline fracture to the printed circuit at the point the socket centre pin connects to board, particularly if you've had to apply pressure over a long period or manipulate the socket to obtain a picture. Also common are dry joints to the chassis connection inside tuner and coils inside I.F. module. If resoldering is unsuccessful then the Tuner & I.F. are expensive parts to replace and probably not worth replacing on an old TV.
