Can you please change the input device to some other you know, works? If you do not notice any problem there, look for the aerial cable going close to any power line or has interference from some other transmissions of any kind nearby.
top half missing is in vertical circuit of set---if it is a 27 inch and this old consider retiring it and replacing----other option is consider having a shop repair it--a rough guess would be as high as 150 dollars parts and labor is possible for your problems.
A horizontal line that rolls from the bottom to the top of the tv could be a Hum Bar. This is from a bad ground either for the house electric system or for the cable system. By code, these grounds are supposed to be connected (bonded) together. In other words, the electrical interference is going through your tv instead of into the ground. Fuzzy picture is usually from low cable signal. This can be due to bad cables, connections, or splitters or problems outside with the drop (cable line outside that runs to the house). Splitters, by design, lower the cable signal (i.e. a 2 way splitter cuts the signal in half). If you have unnecessary splitters you should remove them. If you have more than about 6 or 7 tvs, you may need to add an amplifier.
A line on an LCD, either horizontal or vertical usually means the video driver board is defective or the screen is defective, does it show up as black even on a dark screen? That means a line of LCD "shutter"s is not working and there is a problem that cant be fixed by a reboot or channel change. Bummer.
