That's the high voltage cable between the flyback transformer and the CRT. Use
a wire with an alligator clip at both ends to connect the shaft of a flatblade
screwdriver to the metal frame.
Carefully slide the screwdriver blade under the rubber 'suction cup' on the CRT
so it makes contact with the metal connector in the middle of it.
If there's any charge in the CRT, you'll hear a snap like a static discharge.
(Which is exactly what it is, though many times more powerful than what you get
from a finger to a doorknob.)
Wait a few minutes then repeat. Now you can carefully disconnect that cable
from the CRT.
