I have a 46" Sony Bravia TV that has colored verticle lines about 2-3" wide just left of center.

Yor tv have problem with T con board. T con board is one which drives the pixels of the LCD panel. If any of the driver satge in the T con board is faulty then this problem can occur.

Some times bad contacts on the connections of the t con board can cause same problem. Remove the tv and find out the t con bard. Remove the connections to it and the reconnect the connections. Then check, if the problem remains the same then the tv need a new T con board.

You have didn't mentaioned any model number of your tv. So it is not possible to show you exactly how T con board looks.

Normally in all lcd tvs the tcon board is place on the bottom or top middile position. Which will be cover with metal cover or aluminium foil.

Here I have added a link which will lead you to the picture of T con board for toshiba.( Not exact one)

We are having issues with the screen. The display of our Sony Bravia KDL-40V4150 shows straight vertical lines all the way across the screen. How do we fix this issue?

Sounds like a defective T-Con board, but it is better to test it before replacement. Also there is a possibility to repair it at a lower price. You can find a company that is testing this kind of T-Con boards and repair them here:

The T'Con board [Timing Control Board] of your TV has the fault. Check its strip connections for rigidty. If the connections will get loose, when heat up, the fault you describes her can occur. Check it first. If all are OK, repalce it.

Typical repair shop for 46" flat panel TV repair will be about $200 and up plus parts.
The problem you have can be caused by T-CON board or bad LCD panel, I would swap in the T-CON board first.
See example here: L140 uses almost the same board as 4100 series.

If the panel is bad, then forget about repalcing it since the panel will cost more than new 46" TV.

The part # you gave is the Control Board which sells for $668.79. The T-Con board your looking for is part of the LCD Display Panel and is not sold separately. I suggest you start by cleaning the ribbon cables from the control board to the t-con board. If that doesn't help then you had better take it in to a service center to verify which part is bad because there are no refunds, only replacement after you buy a board.
