When I turn on the tv the picture looks all distorted because of all the lines that are running horizontal across the tv. I have tried all the functions in the setup menu, but no luck.....they just will not go away.

Tv have a problems known as a convergence problems,it dead.The tv colors lines R,G,B mis alingments,have colors shadows pictures or 3D pictures look alike?The tv convergence board have dead 2 STK comvergence ICS and some or all it resistors are dead too.These parts on the tv convergence board,must be replaced to solved the tv pictures convergence problems.The shop,will cost like $300-350 for parts and labors.
At first the picture is ok, and then distorted with horizontal lines i thinks. If the horzontal lines are parellel acros the screen, with an inch apart across the whole screen, your tv needs screen adjustments. Screen voltage may be high. look into the crt base also. Change it first. These also not resolve the problem, LOT may be faulty, with respect to screen focus pack. May need replacement. Try first setting screen voltage to a lower settings and observe.
Is the onscreen menu just as distorted and are the lines across it or behind it? The pop you heard may have been a capacitor and since the TV is still powering on, it's the probably the video controller board that is on it's way out. If the onscreen menu looks fine, you maybe having a problem with the input board only so try a DVD that uses a different input and if it's poor, I would say the TV needs to have the input/output board service. If the OSD is distorted as well then it's definitely the video controller board and service is likely required.
It sounds like a vertical deflection problem. You mentioned you had a white HORIZONTAL LINE in the middle of the screen. If this line runs from left to right across the screen it's in Verticla deflection. If it runs from top to bottom, it's in Horizontal deflection. I am assuming the problem is a Vertical deflaecion problem. The repairs necessary are most likley to replace the vertical capacitors or the verticla deflection chip.

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.
