How To Disassemble A Cingular 2125 And Fix The JoystickThe following are directions on taking apart a Cingular 2125 for whatever reason you need to. Please note that taking apart your Cingular 2125 WILL VOID YOUR WARRANTY. 2125resource.com, 2125resource.com's authors, 2125resource.com's sponsors and 2125resource.com's advertisers take no responsibility in damage done to your Cingular 2125. Perform this at your own risk. There are a few reasons why you may need to take your Cingular 2125 apart, the main reason I can think of, is if you were like me and hundreds of other Cingular 2125 owners who were clumbsy enough to spill some sort of beverage on their Cingular 2125's. And of course, since warranties do not cover cafe mocha under the keys, there's no sense in paying $200 for a repair, or $300 for a new Cingular 2125. The joystick on the Cingular 2125 uses micro-switches to sense the directions pressed. These micro-switches use an electric contact lubricant to increase conductivity. When a beverage or liquid is spilled onto/into the Cingular 2125, the lubricant can be rinsed away, or it could become thickened and non-conducive. There is a cheap, simple fix for this, there's an electric lubricant that almost everyone has in their house. This would be WD-40. Yes, WD-40. I will show you how to fix the joystick on your Cingular 2125 with WD-40.
You'll want to make sure you have everything you need to start this project.
Start off by removing the battery cover, battery, SIM card and MiniSD card. You will see 2 screws at the bottom end of your Cingular 2125, there is also a 3rd screw under the "WARRANTY VOID IF REMOVED" sticker. Now, before you remove this sticker, this is your chance to stop if you do not feel comfortable with doing this.
After you remove the 3rd screw, you need to remove the antena cover. The antena cover is held on by two clips on each end. You can unhook two of the clips by inserting your small slotted screw driver into the holes on the right and left of the battery contacts (see below). Becareful doing this, try to keep the screw driver as parallel to the Cingular 2125 as possible to avoid scratching the motherboard with the screw driver.
After you remove the antena cover, you will see the last two screws to remove. Once you remove those screws, you can use a case opening tool, or credit card, or driver's license to seperate the case. Do this by sliding the opening tool along the sides of the Cingular 2125 and along the top and bottom. Do not force the case apart and do not completely open it yet!
STOP RIGHT NOW! Before you go pulling the case apart, you will need to disconnect the ribbon cable for the camera. You will see the ribbon cable plugged into the motherboard just behind the camera button on the side of the Cingular 2125. Unplug the ribbon cable by gently lifting it up with your small slotted screw driver.
Now you can seperate the case.
Next, you will need to unplug the keypad ribbon cable. This is the copper plug next to the SIM card tray. Again, use your small slotted screw driver to gently lift the plug.
Now you will remove the motherboard from the case. The Cingular 2125's motherboard is held on by 2 clips on each side. Just use your thumb to carefully move one of the clips to the side and lift the motherboard out. Becareful of the screen. The 2125's screen just lays on the motherboard, do not let the screen fall away from the motherboard or you may rip the screen's ribbon cable. You can now see the back of the keypad unit. You will now want to remove the screen lens from the front side case. This is just stuck inside the case, you can just press it out. Becareful not to smudge up the inside of the lens with finger prints. To oil the joystick, just spray a small amount of WD-40 into the joystick unit. Small amount.
Wipe away any excess WD-40. Put the lens back into the case. Wipe any finger prints off of the inside of the lens, becareful not to rub over the black sealing foam or it will leave large smudges that are hard to remove. Use compressed air to remove any dust or lint on the inside of the lens. Reassemble the Cingular 2125 and your joystick should be working alot better than it was. |
