It sounds like a back-light problem. Check all the CCFL back-lights.

I think the backlight is failing, you will need to have it replaced. It is also possible that the backlight inverter (power supply) may be faulty but that usually shows up a fault. I think it unlikely that the screen itself has failed unless it has been subjected to pressure damage.
I hope I have been of help but please do not hesitate to ask if you have any further questions.
I appreciate your vote if you appreciate my reply.

Do these bands appear even when no input is connected to the tv? It will help us isolate whether its an LCD controller problem or a problem with the video processing circuits

SOURCE: Very slow to turn on and has small light spots all over screen

The first thing to look for are swollen capacitors on the power board.replace them if so.

SOURCE: When I turn on the tv, the left side of the screen

It sounds like you have a bad slave inverter board. I've fixed a few of them with the same problem and it's always been this board. With the back off of the tv, it will be the board located all the way to the end where the problem is. It will have several wires going from it to the screen. You will probably have to get the part number off of the board to be able to find one, as I couldn't find one by using that model number.

SOURCE: Samsung 46" TV. Model

This is problem of lcd panel (screen) that is going bad, however, in few tvs, T-Con board was defective that is also part of lcd panel but available separately, t-con board is located on top center of lcd panel at rear side, replace it that might fix tv problem.
Required t-con board is available in for $73 (click the link to view board image and price info) and call local tv repairman to replace it if you are not handy with electronics stuff repair or have no prior experience.
If t-con board replacement does not solve the issue then lcd panel (screen) will be replaced but it would cost you approx new tv price.
Hope these info will help you.
Let me know if you have additional question.

Half the screen isa dark, left side

Most likely you have a faulty LCD panel tabs. This can be verified sometimes by turning set on and tapping or squeezing the top left side of the TV. The only true fix is to replace the panel. I've been told that Samsung may offer to replace the panel or give you a discount on a new TV. Samsung is know to have LCD panels with premature tab failure. So it may be worth while to contact Samsung and see what they can do for you. There are videos on youtube that show case the problems and show you how to patch the problem. just type in "LCD panel tab" in the youtube search box.

Dark line down the middle of my flat screen tv

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.
