How can I stick the TV on the wall if I can't turn it off?

I can't get the TV. Sticking to the wall is as follows:

1. Measure the height and width around the TV and determine the size of the wall material to be cut.

2. Use scissors or wallpaper knife to cut the wall materials into appropriate sizes.

3. Place the cut wall cloth on the ground next to the TV set, and make sure that the wall cloth face upwards.

4. Wipe the TV surface and wall with a rag to ensure that there is no dust and dirt.

5. Place the wall cloth flat on the TV surface to ensure that the edge of the wall cloth is aligned with the edge of the TV.

6. Use a scraper to compact the wall material to ensure that the wall material is closely attached to the TV surface.

7. Stick wall covering on the other three walls in the same way, and clean the whole wall with a rag to ensure that there are no bubbles and sundries.
