If you can see movement in that top line that corresponds to the video you can still see below it, then it isn't really blacked out, it's compressed. This is usually caused by a failed (or failing) electrolytic capacitor in the vertical deflection circuit.
I don't know what labor costs in your area but the part that needs replacement is no more than a couple of dollars. The tech who can repair this would however would have to have a certain piece of equipment (capacitor bridge or meter with DF) to ferret out the bad part.
I have been recommending that folks have their conventional CRT sets repaired, buy a digital to analog convertor for them and park them both in a dry place when you decide to buy a flat panel set; these are failing at a much higher rate than the CRT sets so I don't depend on them entirely.

Vertical line on side of LCD TV

Modern televisions have screens divided into sections. Each section controls all the rows in its area, and it is controlled by its own video separate video driver. If you are missing a line in a section, then a problem has occurred with the driver board in that area. It will be pretty expensive to fix, I hope your warranty has not just expired!

Flickering multi-colored line in the middle of the screen.

You have a failure in the vertical deflection circuit. This could be either a bad vertical chip, the power supply that runs the chip or a bad capacitor in that circuit. This is usually a repair best left to a professional. There is a small possibility that it could be bad solder connections. If genlty tapping the unit temporarily solves the issue you can try and resolder the pins on the vertical chip LA7841 is the part number. There is also a resistor 1 ohm 1 watt. If that resistor is open you can assume the IC is bad
