Problems with vertical lines on a Philips LCD TV

Liquid crystal display (LCD) technology uses thousands, in some cases millions, of small liquid crystals to generate the colors you see on the screen of your Philips TV. The problem is that these crystals and the pixels they form are vulnerable to damage or even to software problems that can generate monochromatic vertical lines on the screen. In many cases, you probably have not done anything wrong to cause this problem.

Failure of the T-CON

Another problem that causes vertical lines on LCD TVs is the failure of the T-CON. The time control board (T-CON) is part of the active matrix of an LCD TV. Its action is to digitize the signal it receives from the TV’s processor to convert it into information that can be processed by the tiny transistors that supply the liquid crystals with an electric current. When the T-CON plate fails, the synchronization between the different plate parts is lost. This can generate permanent and temporary vertical and horizontal lines on your screen, as well as produce pixelated images.

Software updates

Vertical monochrome lines on a Philips LCD (especially those located near the outer edge of the screen) may appear due to outdated firmware. To see if there is a new firmware available for your Philips TV model, visit the manufacturer’s customer service website. If there is a new firmware available, download the zip file to a USB device. Then, insert the USB drive with the new firmware into the port of your Philips LCD TV. The update process will start automatically. Follow the on-screen instructions to complete the update.

Philips policy

Although you can update the firmware yourself to eradicate the vertical lines of your Philips LCD TV, the other problems that cause this inconvenience are not so easy to solve. The failures of the TAB and T-CON are complex technical issues that you can not solve on your own. Contact the Philips customer support website. These problems are covered by the manufacturer’s one-year warranty, which means you should be able to take your TV to be replaced or repaired at no cost.
