LG 42LB6300 : Vertical lines on screen. Ribbon bw T-Con and LED broken

Nidheesh V  there sure is no way to fix it on a DIY level. There are shops that specialize in that repair but the cost will be more than a new panel (screen). The issue is the way the ribbon cable has been “attached” to the panel. That is done via a special bonding procedure (tape automated bonding ). That procedure uses Anistropic tape as the bonding agent and special equipment to apply it. Now I have seen one TV display where some really crafty and very talented person actually managed to solder a ribbon cable in place. Not pretty but he got it working. To clarify , it is not an easy DIY fix but there may be very crafty people in your area that can help you with that. Take a look at something like this and on here for a really good explanation.
