  5. Remove the power cord and place the TV screen down on a soft surface, like a blanket.

  6. The back of the TV is held in place by many small Phillips head screws. Most of these are around the edges but there are also some by the power input and media inputs. Make sure to keep these screws in a safe place!
  7. Per Dave Watson's comment, as you remove all of the screws in the back that at the bottom of the TV, there are two components that you have to unscrew and remove: the WIFI and blue tooth modules. The blue tooth module has a clip at the top that must be pushed down so you can remove it. The WIFI pops right off.
  8. With the back cover removed we can see that everything is spread out. Be careful of the copper coils in the middle as these are part of the TV's power supply.
  9. The board we want to replace is located in the lower right - see red box in image.

  10. To remove the board, we first need to remove all the various connectors to it. Note that ribbon cables are a little tricky with the connector folding down onto the ribbon.

  11. Remove the first mounting bracket - note that it overlays the bottom bracket, the order that these are removed is important.
    12. Step image
  12. Remove the second mounting bracket on the lower side of the TV.
    13. Step image
  13. Note that there is a small amount of soft silicone under the board so you may have to wiggle it lose.

  14. Now that you have liberated the HDMI input board you can send it away for repairs.
  15. While you have the cover off your TV - consider cleaning the two fans as mine were dusty and starting to make some noise.
