REPAIRING AND NOT THROWING AWAY

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

HOW TO DISASSEMBLE APPLE IPAD-2 – HOW TO REMOVE THE LCD – HOW TO REMOVE THE TOUCH SCREEN – HOW TO REMOVE THE BATTERY

How to disassemble Apple iPad-2 – how to remove the LCD – How to remove the touch screen – How to remove the battery


How to remove LCD Screen
Before starting to disassemble the iPad 2, we need to bring to your attention to two areas where the need for extreme caution is necessary to prevent irreversible damage.
On the left side of the tablet, approximately 2 inches from the home button, is the touch screen digitizer ribbon cable. Also on the left side of the tablet, approximately 2 inches to the right of the home button, is the Wi-Fi antenna flex cable.
When you are separating the touch screen from the bezel with the plastic opening tool, below in Step Three, make sure to avoid using excessive force on these two parts of the tablet.
Using the heat gun or blow dryer, begin to heat the outer edges of the tablet to soften the adhesive securing the front panel of the unit (1 to 2 minutes should suffice).
Using the plastic opening tool, create separation between the trim bezel and the touch screen digitizer.
Slide the opening tool around the display assembly to release the adhesive around the entire tablet.
The support of the heat gun or blow dryer might be needed in order to soften the adhesive while working all the way around the touch screen.
Use the triangle opening tools while working around the perimeter of the iPad 2 to hold apart the adhesive and keep separation.
When the adhesive has been released all the way around the tablet, rotate the touch screen away from the base. This will be similar to opening a book. Make sure you are mindful of th ribbon cable in the bottom left corner. Next, locate and remove the four Phillips screws (#00) that secure the LCD to the base.
Lift and rotate the LCD screen out of the base the same way as you did the touch screen. You can then rest the LCD screen on top of the touch screen/front panel.
The LCD screen ribbon cable is held in with a FPC style connector which has a locking tab. Make sure you unlock this tab before trying to unplug the ribbon cable.
The tab on the opposite side of where the cable is inserted is the lock. Use the spudger to flip the tab up 90 degrees.
Once the locking tab is flipped up, release the ribbon cable from its connector and then remove the LCD screen from the iPad 2.
 How to remove Touch Screen
The touch screen ribbon cable is also held in to the phone with FPC style connectors. Again, these have locking tabs that need to be unlocked before trying to unplug the ribbon cables.
The tabs on the opposite side of where the cables are inserted are the locks. Use the spudger to flip the tabs 90 degrees.
Once the locking tabs are flipped up, release the ribbon cables from their connectors. You can now remove the touch screen from the iPad 2.
How to remove Dock Port Assembly
Use the flat side of the spudger to gently pry up and release the dock port’s single plug style connector.
Locate and remove the two Phillips screws (#00) that secure the dock port connector into the tablet, this will allow you to remove the dock port from the iPad 2.
How to remove Front-Facing Camera
The connection for the headphone jack assembly is a locking style connector that needs to be released before the ribbon cable can be removed. Use the spudger to flip the lock and remove the ribbon cable from the socket.
Locate and remove the two Phillips screws (#00) that secure the headphone jack to the body of the iPad 2.
Slide the spudger under the front-facing camera to pry up and remove it from the housing of the iPad. To disconnect the cable for the front-facing camera from the tablet, use the spudger to pry it up and out of its socket and then remove the front-facing camera from the iPad 2.
How to remove Headphone Jack Assembly Wi-Fi Antenna Flex Cable
Using tweezers or the spudger, maneuver the headphone jack assembly up and out of the iPad 2.
Then peel up the microphone that is the last portion of the cable.
Locate and remove the four Phillips screws (#00) that secure the Wi-Fi antenna flex cable to the iPad 2.
The interconnection cable for the power & volume button assembly has a locking connection. Release the locking lever and then remove the connection from the socket.
The speaker assembly has a plug style connection. Use the flat end of the spudger to pry up and remove the speaker assembly
Locate and remove the five Phillips screws (#00) that secure the motherboard to the body of the iPad 2.
Use the flat end of the spudger to lift, pry up and remove the motherboard from the body of the iPad 2.
The final connection for the Wi-Fi antenna flex cable is on the bottom side of the motherboard. Use the tweezers or the spudger to remove this plug and then remove the WiFi antenna from the iPad 2.
How to remove Battery
The battery is secured to the body of the tablet with a small amount of adhesive on both sides of its three pieces.
Use the metal spudger to pry the battery up and out of the body of the iPad 2.
