LG Optimus 3D
Max
Tools
required : Small philips/crosstip screwdriver
Tiny
slotted screwdriver (to tear things apart)
Guitar
pick (also to open things and tear them apart)
Remove
the 3 screws on the bottom plate and the 8 screws on the upper part, all marked
in red.
With
the tiny screwdriver go under the bottom plate. Lift the plate and remove it.
Loosen
up the frame. Remove it carefully with your hand.
We
got to the SIM and SD card board and the motherboard. Start to unpin the
relevant cables and pins marked in red.
Remove
the SIM and SD card board. You removed the pin next to the SD card tray already
and you can see the glue on the board on this picture. Also remove the (whole!)
pin between the cameras, circled in red. Remove the pin shown at the bottom of
the picture. Remove the board carefully.
Let's
remove the motherboard now. Although already pointed out earlier on, the red
marked pins are the ones you need to unpin before carefully removing the board.
There are four pins marked on the top of the board and three in the lower part.
Once you removed them, remove the board.
This
is how the board should look, once it is succesfully removed.
Let's
continue work at the lower part of the phone. Three things you need to loose or
unpin: the sticker that kept the microUSB board in place, the second pin of the
cable and the gold foil circled in red.
Now
it is a little tricky to tell apart the flex cable that comes from the LCD and
needs to be removed and the necessary flex cables that need to be left in place.
I tried to mark the gold foil under the two board parts. Where you removed the
first bit of gold foil should now be two connectors visible.
Use
the guitar pick to detach the glass housing from the housing of the LCD screen.
Be careful, you have to detach a lot of pins. Have a close look at the picture
before you proceed.
You
cannot fully detach the glass because the relevant flex cable has a pin that
won't fit through the opening at the top of the phone. Open it carefully like
shown in the picture.
This
looks a little wild but actually isn't. The LCD sits tight in it's housing.
Take the slotted screwdriver to lift it out of it's housing. The LCD is already
broken. Anyway, let's stay careful. Because of the flex cable of the LCD it is
not yet possible to remove it. Take a sharp small knife or a razor blade to cut
those flex cables close to the LCD. Start where the upper red arrow starts and
work your way down to the second arrow. Now you can remove the LCD. On the
other side you can now identify the old flex cables that you just cut loose.
You will have to remove those as well. Take a look at the next steps.
Start to pull off the gold foil under the cable and don't tear it
apart. Go slow! Remove the foil. You will see there is also a light blue foil
as shown in the second picture. It's attached to the gold foil. Leave it
attached! Once you detached the gold/blue foil, remove the flex cable that lies
beneath the black foil that covers the battery compartment. In the first
picture I marked red lines show where the flex cable lies. You have to tear it
and it won't glue again. Once you removed the flex cable it looks a little bit
like a scorpion there :)
Insert
the new LCD. Work the flex cable through the designated openings. It's a little
messy in the picture, but you will work out how to do it properly.
You
worked the flex cable through it's designated opening? Then take the kept
gold/blue foil and attach it to the new LCD flex cable like it was attached on
the old one. The picture shows how it should like now. You have to fix the
cable that goes through the battery compartment. Use duct tape, or, if not
available do it like I did: use normal tape. Now you are done. I hope you took
notes of how you disassembled the phone. You need to reassemble it now.
