Sony 65 inch screen tv


The lines you saw, i;m sure they are the ones called retrace lines but know the failure could be located on the red CRT board. Most likely the video amplifier is defective and not necessarily the CRT.

Green Flashes - Shuts off


Sounds like the green picture tube is defective. To confirm you can take the front grille and door off and tap the green tube lightly with something plastic, and not to touch any of the adjustment controls to confirm.
