There is a vertical black bar along the left side of my TV. It started as a thin yellow/white bar and has grown to be about 2 or 3 inches wide, blocking that portion of the screen.

The LCD wafer has gone bad, and more lines will begin to appear over time. It can be replaced but the cost may be comparable to replacing the entire television.

Sony bravia kdl-46w4100 moving vertical lines

Check the main filter capacitors at its power regulator board. Replace if found bulged or damaged. Replace all secondary side supply rails' filter capacitors too. The fault is with damaged electrolytic capacitors at the power regulator board itself.

4 year old vizio 42 inch tv lcd. While watching tv, the screen started dimming. There is a 4 inch shadow all along left side of the screen and the 1 inch line shadow going down the middle of the screen.

Maybe a power supply or related issue but at 4 years of age the set has reached its life span----parts will be hard or impossible to find.

If you got four years I would retire it and recycle it and then replace it.

A black line running verticall down the middle of

There is no invertor board on a plasma tv. The fault is the X address buffer board. This is located on the bottom of the screen and runs horizontally the whole width of the screen. If you remove the heatsink plate that covers the x address boards and you need to look at the screen ribbon at the same position as where the bar is (in the middle).Vary gently lift the Xbuffer ribbon lock and gently take out the ribbon.Clean the contacts very carefully with a fibre pen or an electrical cleaning fluid.Insert ribbon back and heatsink and check.Here is a picture of the board and ribbon

a 1 inch bar is associates with 1 ribbon fault. So if the bar was 3 inches in from the left of the screen, the faulty ribbon will be 3 inches in from the right working from behind the TV. If cleaning dont cure the fault, then the Buffer IC will be blown and order a new centre buffer board (you can buy off Ebay)

Samsung 52 Inch LCD 120hz. 3 inch wide vertical line on screen

This is a problem with the LCD panel. If the tv is out of warranty, I would call Samsung and see if they will pay for the panel and you pay for the labor. The panel is not cost effective to repair. If Samsung will not do anything you will need to buy a new tv.

Parallel vertical lines through left side of Panasonic Plasma tv

This sounds like one of the driver boards at the bottom or top of the screen has an intermittent fault. The set will have to be taken in to a service centre.
