Blackview BV9200: Motherboard Replacement

Introduction

A motherboard replacement guide for the BV9200.

If you already know how to disassemble it or have already followed my disassembly guide, skip to step 7.

What you need

  1. Blackview BV9200: Motherboard Replacement, Heating the LCD: step 1, image 1 of 1

    • Begin by heating the LCD. I use a heating pad set to 100 Celsius, and let it heat for 3-5 minutes.

    • If you don't have such a tool, you should be able to use a heat gun. Just heat the edges of the screen.

    • I would not recommend trying to get the screen off without heating the glue.

    • Consider using a more appropriate tool than a part of a box cutter blade to initially separate the LCD from the frame. (I would've tried using iFixit's Jimmy, but I haven't got it yet)

    • Be very careful if you use a part of box cutter blade. You could easily tear the LCD's cables or scratch the underside.

    • Be careful not to separate the LCD and touch panel. When removing the glue with a plastic card, either go underneath the LCD as well or only on the edges of the touch panel.

    • The video is sped up to fit within the 30 second limit. Do it slower and more carefully.

    • Unscrew the screw, remove the tab, unplug the LCD and pull it off.

    • I use tweezers to get the little tab that covers the connector out.

    • Many screws.

    • Ones circled in red are all the same size, and ones circled in yellow are the same size as the one which held the tab that covered the LCD connector.

    • After you remove the screws, get leverage on the bottom. You will see a small indent where you can squeeze a tool in.

    • The motherboard assembly is held in place by 2 latches. Get it unlatched.

    • Once you have it unlatched, pull it slightly towards you, then bend it over so you can see the underside.

    • Disconnect the data cable.

    • Be careful when doing this, as these cables are fragile and it is very easy to tear their heads off.
