  • Lodge the plastic opening tool under and lift the motherboard out of the tablet.

Replacing the broken screen, I stupidly unhooked the LCD with a metal screwdriver. It makes the sound of coming on but no picture. Is that the motherboard?

I replaced screen once before and had no problem except using a screwdriver this time.

  • Place desoldering braid on one of four holes at top back of motherboard.

  • Place soldering iron on top of the desoldering braid on the gray part of hole to lift solder. If confused here’s a reference.

  • If desoldering braid gets covered with solder and won’t lift anymore, just use a new part of the solder wick.

  • Soldering iron will be very hot and can both burn your hand and possibly damage the device.

  • Follow same steps on other three holes.

  • Lift small gray metal piece from the motherboard.

Conclusion

To reassemble your device, place a new metal piece where old one was and solder it to the motherboard in the four holes on the opposite side of the motherboard.
