Introduction

In this case, the tablet does not start, so it is especially important not to damage the possibly working screen. Below, step by step how to do it safely.

Step 1

              tools you need

You will need a piece of soft and extremely thin plastic (an expired bank card is too thick), a larger suction cup (in my case, it’s a pantograph screen opener given to me a few years ago - I especially recommend it), few guitar soft picks, a #000 Phillips screwdriver, pincette and a plastic spatula to disconnect the connectors.
A precision knife can come in handy, but use it skillfully. Most of the components inside are extremely fragile.
The primary action will be to heat the screen. It should be noticeably warm. Heated glue loses its properties and can be separated without using much force. You can use anything, I use a Hit Gun, but other solution is also perfect, such as the original iFixit opener (to be heated in the microwave - WARNING: read the user manual before using it).

Step 2

              Screen heating and lifting

check if the screen has deep scratches at the edge of the glass (especially when the screen is original). When heated and stressed, the glass will break at this exact place. So avoid mechanical action in these areas, if any.
lift the screen with the suction cup in the upper left corner (mechanically this connection is the weakest). Remember that the screen is a set of glass and a slightly deeper matrix. Do not push anything under the surface of the glass, it may damage the screen. If, the reasonable limit is 5mm maximum.
under the edge of the matrix (not a glass - it’s important) slide a guitar pick or other flat tool (like an invalid credit card).
repeat action for the entire left edge of the tablet. In my case, three matrix support points were enough.

Step 3

repeat for the upper and lower right corners of the tablet. Move slowly.
heat the left edge of the tablet once more and slowly (very gently) lift the screen along the left edge - as if opposite to the book.
unscrew the marked screws. I mark the battery port with red, after removing the screw, insert an insulator between the negative pole of the battery and the motherboard pin (a thin strip of plastic, which I mentioned at the beginning). In my case, the battery is completely discharged so it doesn’t have a significant effect

Step 4

              disconnecting a screen connectors

using a plastic spatula, disconnect the connectors (three connections).
Remember that never ever plug these connectors back into the motherboard unless you first put the plastic insulator into the battery port. This can damage the tablet in almost every case.
Congratulations, job done. Protect your screen from accidents. Now you can start the main task for which you took down the tablet screen.
