I have vertical lines in the center of the T.V. It started with one red line and now it has moved on to several diffrent color lines. Also, if the volume is up the T.V. turns off; this started when the lines appeared. I searched the previus problems but only found horizontal lines situations or situations that just talk about one problem. I don't know what to buy to fix the problem (long term)? please help!

If the lines present in the menu when displayed this indicates device mounting troubles. Possibly loose in socket. If you change aspect of displayed image do the lines move, if they do, its an electronics problem, if they are constant, and nothing is displayed in the lines. Tighten device in socket, or seek professional service.
the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.
