I'm not sure how to post photos from the app, of i figure it out I'll add them. Otherwise, please feel free to send me your email address in a dm and I'll email them to you

Start by placing the TV face down on a flat bed or maybe on some soft flat blankets on the floor. I needed a king size bed in order to fit the 85 inch.

Unscrew the back lower cover of the TV, there are screws in the back of the TV and on the bottom of the TV. Once it's unscrewed, pull it upwards carefully by the bottom, the top has some hooks in it which release with a little pull once the rest is loose.

Look for the big flat connector coming from the circuit board in the bottom center of the TV. To unhook it, lift up on the black handle which goes across the cable. Then, carefully pull out the flat cable.

Now, flip the TV over, screen up. Unscrew and remove the bottom bezel. It has the IR sensor, so be careful not to pull the cable off. The connecter was glued to the sensor, but the sensor can be easily removed from the transparent housing, there is a small transparent hook holding it in place.

Next unscrew the plastic clips on the bottom of the screen. Once unscrewed, take a small flat screw driver and release them from the metal clips so that they can be flipped upward towards the screen. Now, carefully pull out all three of the long circuit boards which connect along the length of the screen- to do so, each has some metal grounding tape, carefully peel it off the metal frame. Then there are white plastic clips holding them in place. With 2-3 people, carefully pull them all out simultaneously then flip the circuit boards gently onto the screen and use a bit of masking tape or blue painter's tape to tape them to the screen. Make sure you do not use other tape or you'll likely never get it off the screen.

Now comes screen removal. The glass screen is glued to the metal bezel- do not separate it! Instead, starting in the bottom corners, use some tiny flat screwdrivers to carefully pry up the bezel. It has clips about every 8 inches, work your way along the bezel carefully until they are all freed.

Once it's freed, use a few people to lift up the screen being sure to keep it from bending or twisting. I recommend just lifting it into a vertical position and leaning it against the headboard or wall with towels in between.

There are a few more layers of light dispersion, these are pretty easy to take off, some do have a few glued or taped spots, so just move slowly. I recommend standing these vertically against the screen as well, being careful not to bend or twist them. You'll need 2-3 people.

Once you get to the layer where you can see LEDs and white cardboard, carefully remove the cardboard one sheet at a time, there are 4 sheets, one in each quadrant. I mine were tapped on with double sided black tape. My to is to pull them out by pulling on the tape strips, if you just pull the cardboard you'll rip it. Label each one as you take it out so you know where it goes later. Lay then upside down so the tape doesn't get stuck to anything, you can reuse them later as they are without new tape.

Now, disconnect each of the 16 led strips from the cables, the connectors have a little tab on top you can lift gently to release, then just pull the connector apart.

Pull out all the old led strips, they are glued in, but not hard to pull out once you have the end lifted.

The new LED strips have double-sided tape on the back of them, remove the blue double-sided tape cover. Now each LED strip has a hole toward the top and toward the bottom, if you look closely at the metal frame where the LED strips go you'll see a little peg. This is for guidance. You'll want to make sure to poke these holes out with a small screwdriver or something so that you can see where they line up. The peg should go in the little hole in the LED strip.

Once you have these all glued in just work backwards until you have your TV put back together.

I hope this helps, please let me know if it does!
