Most likely there are electrolytic capacitors in the power supply, video path, and scan amplifiers that are starting to fail from age. This is common in many of these sets. In consideration of the age of the set, this may not be worth having it serviced.

If the screen works for a short while and then completely fails once the TV warms up you have a problem with the main unit video board or the LCD control logic board. Most often if the picture cuts out but audio continues to work the logic board is over heating and should be replaced. However if the picture cuts out and audio shuts off as well then its your video input board.

One thing you should not do with electronic devices which have a start up proceedure is to turn the power off, and then on again without a wait of about five minutes. Some equipment manuals warn you about this, and specify a longer period. The start-up has to have time to reset. It will be more likely to reset if you do not leave it on standby, and even unplug it. In your TVs case you need to describe the distorted picture as it may give a clue to a fault, or incorrect start-up. The horizontal line indicates the frame timebase had stopped working. No picture could be a fuse blown inside the set, or a timed cutout which may reset after a time. Try after several hours to see if it comes on. If it is just the frame timebase (vertical) it is worth repairing.
