Absolutely right. See my comment above. Carefully prising with the right tools between the display and the frame - the bezel - and working around the outside of the display will eventually cause the bezel to come away from the display with the back cover attached. You can then access the parts you need to get to.
If you remove just the back cover - which to the uninitiated does look less scary than trying to get between the bezel and the display - you will destroy the tiny plastic rivets that lock the cover onto the bezel. More importantly, you will then find that getting to the parts you need to replace is rendered impossible because they will be hidden under the bezel, which of course will still be in place. So the correct way to take this tablet apart is the more challenging way i.e. separate the front display from the bezel and rear. But with care and the right tools this is still not too difficult. And if you are in any doubt about this, it is worth pointing out that in all of the photos below from Step 4 onwards, the work shown is taking place with the bezel removed. There is nothing written in this guide to indicate that this had to be done.
