Hi,
Your tv have problem with the T con board. T con board is one wich drives the pixels in the LCD panel. There is no repair possible with these boards. You have to replace the T con board. Normally you can find the t con board in the top centre or the bottom centre of the tv covered with metal cover or aluminium foil.
Here i have added the link for T con board you can fin the picture of the board in the link

Ajin

SOURCE: P2 42HD - Picture OK on right half ... vertical bars & black on left side

I just got quoted $705 from the Vizio certified repair partner. Nice. Nice and way too expensive. I may as well buy a new TV instead. It certainly won't be a Vizio. They told me a I needed a Y systainer, C systainer and a right-driver board.

Lame. I'm trying to find something local.

SOURCE: left half of screen is filled with vertical

If I am right, this is an expensive problem.
The minute pixels that make up the display are turned off and on by circuits arranged in an X-Y matrix. To avoid using one circuit to control each pixel, the circuits are rapidly scanned at a rate higher than the eye can detect.
One or more of the circuits that do the scanning have failed on your set and the ugly part is, the display panels often have these mounted on the display itself forming a 'package' that speeds assembly and are made only by a few companies. If yours is one of these, the entire panel would have to be replaced since the integrated circuits used are very small and have pin spacings that pretty much preclude replacement by hand since they were originally placed by robots.
I hope for your sake the display panel and its control circuits are separate and the panel is still fine since the cost of an integrated replacement may prove to be about 1/2 to 3/4 of the cost of a new set.

Panasonic TC-P65VT25 has a black vertical line half way down screen.


Sounds like you've had a failure of a part in the electronics. Plasma TVs use pretty high voltages (like the old picture-tube models) and parts can get fried over time. You'll need to have your Panasonic serviced by a qualified technician. Don't try to do it yourself -- high voltages, remember?

Dell Latitude D505 half of screen is black with colored vertical lines.


Sounds like you have a section of dead pixels. This can happen if the laptop has been dropped a lot or stepped on or some type of impact on the laptop. This is a hardware issue. You will need to have the screen replaced. In my opinion, by the age of the laptop, its better off getting a new one.

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.

Left half of screen has vertical color bars of different colors


Hi

This will be your screen controller board that has failed also known as the ldv's board, With the back removed from your TV it will sit below your power supply and be connected via a ribbon cable to your Y Sustain board on the left.
Remove it and take the part number of the board then Google or Ebay for a replacement.

Take a look at the below link so you know what you are looking for.
Hope this helps

Right half of screen is Black with a White vertical stripe


Yeah, I have this exact same problem, except my mom slammed my laptop shut in frustration around half an hour ago, so that's why it's like this. The right half of my screen is black with two colorful stripes (mostly white), but the left half is visible. I've researched a bit and found out that this is because the LCD in your monitor has burnt out, and since you don't have a monitor to attach, the only thing you can do is to go to where you bought the laptop and either get it fixed for free or return it for a brand new one (if your warranty still stands). If not, you might as well get a new laptop. I think my warranty has expired, so I'll get a new laptop, hopefully.

Hope this helps!
