It's been a while since my first pictures were posted for the internal
components, so after a few requests I have decided to create a guide on
how to take the phone apart.
These are all new pictures which include the never seen before keyboard stripped down to expose the circuit layout.

To open the main body of the phone you need a T5 Torx screwdriver
(I have posted in the past saying a T4 but later found out that was due to my old driver being worn out :oops:)
Remove the four screws, then you need a small flat bladed screwdriver to
unclip the two retaining clips in the middle sides of the body see below pointing to one of the clips, the other one is on the oppersite side.

Once you have uncliped the cover, lift back from the battery cover release end to remove the cover out of the way.
Now you can see the SD card socket

After removing the screen connector strip, can be lifted out of the way
to expose the Keypad buttons and keypad membrane side of the circuitboard. You can also see the internal battery.

The metal keypad membrane support plate can be carefully lifted to show the components underneath.

This next part I do not recommend anyone to try unless you want to risk destroying the keypad. I removed the membrane from the backing plate
and then proceded to seperate the top memberane from the circuitboard.
As you can see this is the matix layout of the keypad.

I went this far in my testing to find the actual cause of the DownLeft problem on the main controller.

Now to move on to the Flip section of the phone.
On the display side there are four rubber plugs, remove these and then the T5 Tork srews underneath them.
Now the hard part, there are two clips either side of the case which have to be lifted very carefully with a small thin blade. You have to be carefull
otherwise you will mark the case as the top cover is plastic.

Once you have done this on the hinge is another clip, lift the cover from the top (speaker end) and carefully slide the cover towards the hinge.
Failure to do this will result in the clip being broken off.
You can also see in this picture the vibrate motor and the magnet used for activating the main screen on and off.

Once you have the cover removed unclip the connector cable then you
can lift out the display circuitry.
Note in the two pictures the earpiece speaker and hands free speaker are one component mounted back to back.

WOW good work and what i did to my SPV i woont be planing to do that to my mpx220 anytime soon  :wink:  .

[awarner]

[COLOR=blue]Right I've been playing again and due to a question asked about the
backlight I've decided to go another step further
Here are new pictures of the backlight stripped down to show how it works.
The light is generated by three white LEDs based at the bottom of the
screen and gets reflected via a prismatic plate very similar to the SPV.
The advantage the MPX200 has over the SPV it that this plate is at the
back of the display rather than on the front so it not prone to the
handling damage the SPV had.

Fascinating!  

[madmaxedcn]

can u pls tell me how the backlight turns on and off.. like what is the mech than turns it on or off magnets , deep switch,? my backlight keeps on going out i put a little preshure on it it goes back on.

[awarner]

The backlight is controlled by a small magnet (in yellow in the pictures above)
This is a very strong magnet so your problem may be a loose connector cable
ehich does not seem likely as it is clamped into place.

[aurallydrifting]

ok you guys are truly crazy!!
I'd never be able to piece that thing back together after pulling it apart like that

[MadSci]

This is really COOL!   =D>

I love to see "what's under the hood" like this, although I'm envious of your skill with these tiny parts.  My meathooks would make hash of them for sure.

One small queation, Where is the Internal Antenna?

Thanks!

CROSSPOST WARNING!

Anyone have the guts to do the same for the MPx220?

Fair warning - I don't!

Nice job Awarner! Did you do this just by yourself (no instructions...)?

Some of the pics aren't displayed! I can't see them.  There only says: "user posted image".

[awarner]

Yep all my own work and no instructions
As far as I'm aware I was the first to strip the MPX200 and give instructions on how to do it. It was an interesting learning curve but
regarding the images I still need to sort them out as the link for them was lost when the site moved at the beginning of the year.

[onk]

Who have stripped mpx200
write to forum texts from chip used in mpx200

[awarner]

Welcome to the site

Which chip? and using "please" can work wonders

CROSSPOST WARNING:

Hey, any chance you've had the courage to do something similar to an MPx220?  I'd love to see it!

Give me an mpx220 and I'll have a go.
