When dismantling any phone, great care should be taken to ensure that no damage is caused to any of the parts. Rough handling may result in severe damage of many parts, and if proper anti-static procedures are not followed, electrostatic damage may result in any electronic component.
Before commencing, it is recommended that the correct tools are purchased for the job in hand. At the very least, you will require a Torx T6 screwdriver. Do NOT attempt to use a small Allen key or filed down screwdriver, you will only damage the screws.
Step 1. Ok, to start with this is a fairly simple phone to dismantle! However, the LCD is hard to swap! TAKE CARE. The main tool used to dismantle is a Torx T6 screwdriver. You will need a soldering iron somewhere around 11 - 15 watt and flux free solder to swap the LCD's.
Step 2. First of all take the battery off. Then the clip that holds the battery in should be pushed back the other way and it will slide off, uncovering 2 x T6 screws.
Step 3. Next, remove the 'SEAL' sticker under the battery and remove the 'MOTOROLA' sticker on the rear beside the aerial. These will all reveal screws! The RED circles donate screws. The BLUE square donates service points and the GREEN square donates battery contacts.
Step 4. The phone will now pull apart to reveal the picture below. The BLUE circle is the Vibra motor, the RED circle is the ringer. The RED square is the hands-free/unlocking point. The BLUE square are the contact points for the vibra motor and ringer. The GREEN circle is the in car kit aerial point. The YELLOW circle are the SIM contacts and the YELLOW square is the charging point. The GREEN square is the microphone contact. The PURPLE square is shown in more detail later.
Step 5. Now remove the main circuit board and LCD from the front housing. Ok, there are a couple of errors on this. Both the BLUE and GREEN squares are nothing to bother about! The RED circle is the earpiece, the RED square is the internal battery, the BLUE circle is the contacts for the earpiece. The PURPLE dots are LED's. NOTE there are only three on the LCD area itself. The RED line indicates the keypad membrane.
Step 6. As promised two pictures ago, here is the base in more depth. The RED circle indicates the microphone connection. The microphone itself should face rubber side up. The copper rings on the base make connection with the circuit board contacts. The RED dots indicate where the Charger is sited. PLEASE NOTE, this is a very regular problem with all Motorola's. The charger points, if knocked whilst the plug is in, tend to pull the charging block off the circuit board. Using the afore mentioned soldering iron, solder back in place. The earpiece is done exactly the same way.
Step 7. Now comes the real fun! The RED square shows the screen connections. The LCD is broken off on this illustration for ease of viewing. The YELLOW line shows a double sided sticky tape which holds the LCD frame in place. Beware as it is tough, DO NOT bend the circuit board in an attempt to get the screen off!
Step 8. In a bit more depth now, the picture below shows the screen slowly being de-soldered. Slowly and lightly run the soldering iron back and forth over the contacts whilst pulling the LCD. It will slowly pull off. DO NOT RUSH THIS. In some instances heat is not even required but it is best to use an iron. (soldering iron that is :-).
Step 9. With the screen now off, you will note it is actually contained in a small frame. Simply insert a sharp item and lever out ensuring you DO NOT break the clips holding it in place. BEWARE the LCD is also held in with the same double sided tape!
Step 10. Right the screen will eventually break free. We have indicated the double sided tape on the frame in YELLOW.
Step 11. This picture is possibly slightly out of turn. The RED lines indicate double sided tape which holds the LCD frame in place. The RED circles indicate the 3 screen LED's and lastly the RED square indicates the LCD contacts. It may be worth adding a very little amount of additional solder to these at this point! NOT TOO MUCH THOUGH!
Step 12. The New LCD then fits back into the frame. If the double sided tape has lifted stick in new tape. The BLUE square are the LCD contacts which should be soldered to the board. The GREEN square indicates, possibly the best aid ever. This is a strip of double sided tape which will hold the contacts in place while you solder the screen back in place!
Step 13. Not too great a photo, but once you have the contacts lined up and the screen stuck in place with the double sided tape begin soldering it in place. It is best (so I have found) to site the LCD contacts about 1mm short of the end. This way you can add a little spot of solder to ensure a good connection is made.
