My daughter cleaned tv with liquid spray, which seems to have seeped in and caused some damage. So display has turned nad amd getting only vertical lines. Technician visited and suggested changing panel , but i dnt trust these guys. How can tv be fixed? Update (07/07/2018)

nikhil jain before replacing the panel (which will be expensive) you do wnat to take the back of your TV and take a look at some obvious damage. Post some pictures of your boards as well as the top of the panel with your question. that way we can see what you see. Use this guide Adding images to an existing question for that. In particularCheck the T-con board. That is the board where two ribbon cables go to the actual panel.
