I have three lines running down my screen...one is wider on the bottom then the other two. It almost looks as if liquid got inside and there is now a smear on the inside on the screen. Is this something that can be fixed or should I scrap the TV?

Sounds like panel fault. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent.
Most LCD and PLASMA sets use two boards (some combine them into one board) that drive the Display Panel (the entire front screen unit) so I would suspect one of yours is bad.
The other unpleasant possible cause is where the left board is connected to the Display Panel (entire front screen unit) you have a problem inside that Display Panel and that is fatal as there is no way to get INSIDE the panel---it can cause both lines and a dark picture on one side of the screen.
that is usually caused by cleaning the screen with windex the windex runs down the screen bewteen the screen and plastic frame and actually seeps inside between the screen layers. Eventually it may go away by itself if the circles are not too bad but in most cases the damage is permanent.It can also be an issue called screen delamination which there is no fix for.
usually you can correct this issue with only a few system checks, dark streaks can be caused by damaged pixels on the screen, in which case you need to replace the TV.
Inspect where the dark streaks are on the television. If the streaks occur at the same place on the top and bottom of the screen, they are due to the formatting of a movie or television show you are watching. This is normal. Also, if the streaks appear on the left and right of the screen, they are due to the show being filmed in full-screen instead of wide-screen. This also is normal.
Change the input setting so you are viewing the contents of a different device. If the dark streaks are gone, you know they are due to the device connected to it. However, if the dark streaks remains no matter what input the TV is connected to, the problem lies with the television.
Inspect the cable connection. Oftentimes when connecting a computer to an LCD TV, you can have strange dark streaks across the screen. Use a DVI-to-HDMI cable connection when plugging in your computer, then press the "Menu" button on your TV remote, select "Picture" and chose "Square Pixel." See whether the image adjusts and the dark streak goes away.
Contact the manufacturer of your LCD television if the dark streak remains. This streak can be caused by a defect in the television; if the TV is still under warranty, you can have it replaced.
If it is contained in one area then it sounds like a crack in your panel, which will sometimes produce blue, green, purple lines up and down set. Somewhere in there if you look there maybe a scratch along the bottom screen or somewhere that goes the opposite way. If this is the cause there is nothing you can do about it. Panel is bad and replacing will be too expensive.
Hi, I have a Sony Grand Wega LCD Projection TV that has a blotted gray streak across the front of the screen. I only use a damp cloth to clean the window and that doesn't seem to help. It really shows up on light pictures and is unnoticed when the picture is a little darker. What can I do to fix this problem???
If it's an LCD TV, then what your seeing is Liquid Crystals inside.
Chances are that someone has bumped the LCD or damaged it, and now the
screen is broken. The "Dark Lines" are from misfiring pixels which is a
sign that the LCD is damaged and will either stay the same, or get much
much worse. I'd lean towards much much worse.
Just keep it until it really gets bad then just replace it. You can have it fixed, but the repair would cost more then just buying a brand new one.
