In this video will show you how to quickly fix fix lg led tv that has sound but no picture
my have LG smart tv have this problem it will show light indication that it is turn on but it is not displaying anything on screen it is completely blank.
THIS TUTORIAL CAN BE USED FOR ALL LG 42LN , LG 47LN MODELS
so i will fully dissemble the tv and fix the problem
After i've checked my led strips .i identified only 1 strip was faulty .so i replaced this led strip to fix my LG SMART TV blank screen problem .
This will also fix a LG TV that flickers, it will go on and then off every few seconds. This is a known problem for LG TV's even though they are only a couple years old, what will go bad are the LED lights.
I hope this will help you fix your your LED tv aswell.
