How to strip the MPX200 (With Pictures) UPDATED

[Guest awarner [MVP]]

Ok one post at a time :)

Voit,

Off hand I am not sure without taking the phone apart yet again :D but I would say it would more likely be earthing tabs on the headset jack socket.

death_me,

There is no easy way to work on the hinge assembly and it is very hard to take apart.

LJWhorfin,

Unfortunately I do not know of anywhere to get a ribbon cable from and Motorola do not sell spare parts on component level.

Here :)

can you attach something to that to help with the signal? and what is it? the picture doesn't show. i have almost no signal in my house with this phone. with my old one, i got plenty here... really love the phone but if it gets no signal, then it doesn't do me any good.

You can't mod the phone to have a better signal. There's been a fix (illegal) floating around that fixes some things and some reported a boosted signal with the new rom. You have to flash to 2003 though I believe, so you'll have to track down 2 hard to find and illegal roms.

Good luck :o.

I'm stuck at the second step. :D I took out the screws, but I don't know where to put the screwdriver to unclip the cover. If I put it in the two holes facing each other, I can press a little, but then the plastic gets all deformed and I'm too scared to press harder.

Could someone please explain in detail how to unclip the body?

Can you show again where the Internal Antena is? Is this thing responsible too triband (900/1800/1900MHz)? Sorry for my english ;)

[Guest awarner [MVP]]

It's not the antenna that is responsible for the network bands it's the components they use on the circuitboard.

Some people claim that the dualband AT&T MPX200 can be made tri-band but I have yet to see actual proof of this. It was believed that some of the original AT&T MPX200 phones were tri-band as a mistake

in the initial supply.

[Guest vasteq]

Can you tell me where on MB are this components? It's the LCD MB or Keyboard MB?

[Guest awarner [MVP]]

The chip is on the main board but I am not 100% sure which one it is from memory.

[Guest xxcrashxx]

main pix aint working.

[Guest awarner (MVP)]

They are now :)

I've been trying to find the time to get it sorted but unfortunately work has been getting in the way. They stopped working after Wmdevices closed down.

[Guest NeoXon]

My phone had the "won't charge any more" problem, and I managed to fix it. Thanks, awarner!

But I have a little problem. I don't know if this happens because I've stripped my mpx, but now I'm having this:

at random times the main screen goes off and also the keyboard gets locked. Like the phone's flip (the display) was closed down, although it was not.

I guess it might be the case that the sensor which is responsible for determining whether the phone is closed or not went wrong. Can it be the magnet? And where can I find it exactly? In some of the posts I found out that it was a yellow little magnet. However, I still haven't managed to find that. Where should I look for it? If its not faulty, what could have gone wrong?

' date='Jul 4 2004, 13:35' post='421079']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.

That is awesome...

Could you show me where is antenna. My mpx220 signal isn't stable how to fix it?

[Guest awarner (MVP)]

Your problem is probably down to the fact the MPX200 has never been a good phone for reception.

The antenna is located on the base of the phone in a void below the hinge. There is not really anything you can do to improve reception, as changing the properties of the antenna can have adverse effects and can damage the phone unless you know what you are doing.
