Hi, the appearance of black streaks on the screen of a Sharp LCD TV is common problem most customers will have to contend with. One of the most visible signs is the appearance of a message that reads " loss of sync". In this situation, the individual will still hear the sound coming from the LCD TV but the picture disappears especially within 10 minutes of putting on the TV. In some other cases, small horizontal lines may develop on the LCD screen especially when an object is thrown at the screen -the horizontal lines develop at the spot where the object hits the screen, and these lines are often visible when the TV is turned on and such problem is characterized by Grey color screen with no pictures.

Another common situation is the appearance of vertical red line across the LCD TV screen. In this case, the connection from the internal ribbon connector and the display has been effected. This problem may degenerate into the formation of two screens which are separated by a black line .

LG TV screen repair for Black streaks on screen

The best possible LG TV screen repair for vertical lines on your LCD screen is the replacement of the screen itself. It would be ideal for you to know the warranty status of your LCD TV before returning it to the manufacturer. In the case of the formation of black streaks on the LCD screen, a possible reason is that one of the substrates in the screen has been fractured or it can be a result of the release of some bubbles within the screen, especially after the screen was hit by an object. You don't have to think much about this problem, as it should be in your best interest to get a LCD TV repair service to replace the screen for you.
In some other cases, some other components of your LCD TV screen might have been broken down { hardware problems} resulting in black streaks or the formation of Grey or black color on your screen, you will need to get your LCD TV screen undergo some diagnostic procedures before the problem is fixed. This will help you avoid future re-occurrence of the problem.

Thanks for using fixya.....

Hi, my 42" LG TV displays a black vertical line to


The so called plastic strip is not plastic, it is call Flexible Printed circuit board made from KAPTON, they are not soldered on to the LCD panel but they are ultrasonic welded on, it is obviously that people that tell you to resolder the connection never senn or work on the LCD panel before.
I would try reseating the ribbon cables between the T-CON board and the LCD panel first. Worst case will be bad LCD panel.

I bought a lg 42 inch 42lg30 lcd panel broke screen 80$ off Cl ?


The cost of a screen from LG is £430, this is a trade price so you would need to add on extras such as VAT, handling/delivery charges etc, which could take it to near £500. Possibly try looking on e-bay for any cheaper alternatives as this would take the cost close to the price of a new TV.
