lalo nayung wire na nakakabit sa picture tube or crt nakulay itim na may cap
Taking apart the TV or crt monitor can be very dangerous. High voltage presents inside the CRT - even when the power is off! And the CRT is fragile. You could get seriously injured or die.
If you discharge the CRT by connecting the anode (suction cap) to the ground, but not removing the anode cap, then the tube can charge up again. After removing the anode cap, the tube cannot charge up again as there is no circuit.
