Picture is shrinking?

The fault is most likely due to dry soldered joints to the frame output IC or associated circuit.

Moving the co-ax plug is simply flexing the printed circuit board, causing the bad connection to make and break, in a completely unrelated part of the TV. It's just on the same board and the mechanical movement is showing it up.

A frame fault is usually very simple and cheap to fix.

However, straining the aerial socket could result in a very expensive tuner repair. So it's best not to move that around any more. As thats not where the actual fault is.
