My sony LCD tv bottom third of the screen is several shades darker the the rest of the screen. Also at time there are vertical lines in the shaded area of different colors.\r\n The TV is only 2 years old - what can I do, if anything? Model kdl32l4000

You may try a new T-CON, but most of the problem could be a display panel.

How to fix repair vertical lines on half of LCD tv screen

T-Conn panel could be defect but i guess it's the LCD panel.

The filter is probably covered with dust at the sides. In an LCD projection tv the light has to pass through the filter(prism) before it displays on the screen. If its dirty then you will have a darker than usual image. Getting it cleaned should resolve the issue.

Hi,

All plasma an lcd TVs have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times resetting the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They can sometimes be fixed, but it is a pain. An yes I have done it, and the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken if you decide to tinker with em, the usually have lift locks that release them, but it is very easy to wreck em.


Good luck.

see the screen resulotion

in an LCD panel there are several floresant bulbs..they have either worked their way out of their socket or gone bad you need a tech to check it out

Probably one of the backlights have faulted
