The vertical drive ic that drives the yoke for vertical sweep has blown.
sometimes it is solder problems like sharp and toshiba had.
the part is 10$ the pc board will label it ,the yoke is the coil setup on the picture tube.if you follow the wiring half goes to the horizontal drive,and the others to the vertical section.the chip drives the coil directly.there are VERY high voltages in there ,even turned off. the pix tube cap on top is 30000v. like a stun gun.the horizontal drive 2000 volts and the main power supply 165 volts dc high current.you need a special setup to discharge the picture tube.

Green horizontal lines on screen no picture


The green CRT's (color picutre tube or color wheel, or ballast) will need to be tested for replacement.
It is quite common with these tv's

You will need an ohmmeter and or voltmeter and test each component for currency and accuracy

TV problem


Hello Barbara76,
Is this a Horizontal line (inch or two) across the screen, if so
the fault could be either a faulty Vertical IC,Faulty Electrolytic
capacitors or just simple dry joints.

This problem sounds like a short inside the picture tube itself unless a driver transistor failed that drives the red gun in the CRT. You may have to take it to an authorized repair facility if the picture tube is still in warranty.
