It never pays off for me to answer these kinds of questions, in the answer box. 95%+ chance the problem is a capacitor or inductor filtering the signal or a transistor going out on the LCD controller board attached to the LCD. Most places that work on LCD TVs should be able to fix it for less than the price of replacing the LCD screen. The alternatives are live with it or replace the LCD screen.
