lines coming down the Tv screen

@jeh83 if those lines disappear after warming up, it sounds like a cold solder joint. Could be on any boards, but most likely the T-con board. You could try and replace it or use some freeze spray. Remove the back of your TV (do not touch anything) . Then turn the TV on and once it warms up so that the lines disappear, spray some freeze spray on the board, cover a few components at a time. Once you get the lines back you will discover which component is giving you problems. Post some good images of those boards with your question. that will allow us to see what you see. Use this guide Aggiungere immagini ad una domanda for that.
