  1. open back panel (note do not touch any of the Boards and components on them unless you have good knowledge of ESD).
  2. connect TV to power and turn it on in a very dark room. you will now find out what works and what does not.
    1. if you can see white lights on the back of the TV then Back-light is working and visa versa
    2. plug your cable device in with the correct input selected. either AV1/HDMI1 will usually be top of the list now listen for sound
    3. Now while in the dark use a torch or your eyes if you are not in the dark, option 1 comes highly recommended. Look and see if you cant see a feint image of the menu
  1. Now your troubleshooting is completed its time to interpret your results.
    • If 2&3 are a yes and 1 is a no then replace LED Driver. Still persists then the LED strip/LED's are damaged
    • If 1&2 are a yes start by replacing t con board. Still persists replace the main board
    • if the only yes is 1 then you definitely want to change the mainboard
    • Now guess if nothing is on, what is probably the cause?
    There is however a much shorter procedure and if you are a logical thinker you will not only learn exactly how LED TV's operate but also how to shorten this solution OR call a guy/girl that has the magic touch
