As always, this is at your own risk. I am not responsible if you ruin your TV or injure yourself in any way.
Step 1: Remove the back of the TV
I have color coded all the images:
All red arrows are screws that should be removed
All Green arrows are cables that should be unplugged
The 3 blue arrows point to the orange rubber bumpers (they are semi difficult to peel off)
The Xs are screws or cables that do not need to be removed.
Note the 2 screws in the upper corners of the recessed AV Input area
Once all the screws are removed, this part should come off fairly easily, but the power cable still goes through it, so slide it along that and set it off to the side. Note that there are 3 different screw types here: two small ones from the AV Input area, 10 from the sides and top, and 4 slightly longer ones from the bottom.
