Hello I have a Sharp Aquos 70” Model# LC-70TQ15U that has developed a red vertical line down the middle of the screen. Just wanted to know what has caused this and what is the fix. Any information is greatly appreciated.
To fix a problem, you need firstly to find out what has caused it. One possible cause that might be repairable is a bad contact in the connection between the LCD screen and the printed circuit board that drives the rows of LCD image pixels. These lines represents dead image rows showing one constant color through the entire line rather than the actual image. Although you might be lucky to fix this by opening the TV enclosure and pressing on the connector (these would be contacts between the screen and the main printed circuit board) and if you clean the contacts the full image might be restored but I would not recommend it. If you have warranty just return to store for replacement. Thank you!
