Vertical scan section circuit fault. Check and replace damaged component/s at its vertical scan output section circuit. If you wish to get some details, check the site linked here.

Have you checked all the connections at the back of the tv?

This is for if the lines are thin and in the form of an arc across the screen.

You need to turn down the screen voltage for the blue and red CRT. I believe the access is through the front on that model.

1) Remove the front grill
2) There should be access panel you need to remove once you remove the front grill. This is where the screen voltage adjustment is located
3) Look for a small black box with six knobs on it. One row is for "Focus" and one row is for "screen". It will be marked, but probably need a flashlight to see which row it is. There will be a "R", "G" and "B" next to each knob to represent Red, Green Blue respectively.

4) Careful with the access panel removed, you are only inches away from very dangerous voltages.
5) slowly turn the R or B knob counterclockwise until the lines on the screen disappear.
Keep your hands away from everything else and only use one hand near the tv. put the other hand behind your back.

6) Once corrected, replace the panel and put the grill cover back on.

The issue is that the monitor in not getting the signal. This tells me that the video adapter ( or on board video) has went bad. Try another video card if all your doing is social media and surfing you can pick one up for around 20.00

Ur tv convergence ICS are dead.U have tools to do soldering,and know how to do soldering?Must replaced 2 STK convergence ICS,and some or all it resistors.Tries websites like Tv repair World.com,Tvrepairkits.com to buy a convergence to repair it ur self.The shop will cost u $300-350 for parts and labors.

It is problem of LCD Panel that will be replaced.
Please check with dealer / store for extended warranty option.

Sounds like a bad video card.A video inverter could cause distorted graphics but usually it turns out to be the graphics card.

The ribbon cable to the drive has either came loose of the drive itself went bad. You can open up the back if you are confident and see if adjusting the cable gets the line back. If not you will need to replace the Upper Y Drive.

Thanks
