Are you certain of the connection? Sometimes the connector becomes loose or otherwise loses integrity. Maybe it's the cable (HDMI, right?)--or both the TV's connector and that. They may become worn.

Be careful with your LCD screen--they are more delicate than most people realize.....

A poor solder connection on B+ is the line, Horizontal drive transformer or at the base of Horizontal Output transistor can caused that. Re-soldering these section can fix it..

Not exactly an Ideal fix , but running a fan into the back of your tv seemingly corrects this ... cooling failure ?

It is my guess that you have some intermitent solder connections in the Vertical output circuit.
Hope this helps,

Hi

what line started? from Left to right? or from top to bottom?

Thanks!

Vertical hold circuit is failing.

Check capicitor in vertical hold circuit. You should have solid knowledge of electronics repair before attemping repair. TV's can emmit harmful radiation, and produce voltages up to or in excess of 30kV.

Its may due to problem on IFsection or tuner,afc problem

You likely have an elevtrlytic capacitor bad on the B+ line to the vertical ouput ic. If you continue to use the set like this it is likely the vertical ouput ic will fail.

Sounds like you have a power supply filtering problem. Perhaps a filter capacitor is going bad. If your set has a switching power supply oscillations from it are getting into the video. You need to have a tech to check it out for you. You should get an estimate first before having it repaired. Stargazer
