@jibinjoy could be bad connector or bad TAB’s You do want to open up your TV and reseat all connectors, check for corrosion and check the caps on the main board. Also try some different video sources (HDMI, Component, DVD etc) It might help if you post some images of the errors (lines) as well as your boards. That way we can see what you see. Use this guide for that. Update (06/12/2022) madhu kiran that is a failed TAB on the Gate drivers. There really is not much you can do as a DIY’er. Sometimes putting pressure on the ribbon cables that are glued to the LCD panel might work, but there is not a high success rate.
