how to repair the iPad3's LCD cracking, the screen not reflected, and the display failure, and how to disassemble it
- [STEP 1]
If the LCD panel is displayed incorrectly or there is a line on the screen, it will be a liquid crystal failure, so it is necessary to replace the LCD panel.
First of all, a strong double-sided tape is attached to the part filled with red, so I warm it with a dryer and float the double-sided tape.
If you have a heat gun, work efficiency will increase.
Please note that if it is too hot, burns and parts will deform or break due to heat.
Before you start working, leave the iPad shut down.
- [STEP 2]
Suction cups are sold at home centers and are mainly used by glass shops.
There are from large to small, but small things are enough for disassembling the iPad.
When the touch panel glass on the surface is broken, it does not stick firmly, so the work becomes difficult and patience is necessary.
Also, be careful not to get hurt by broken glass.
- [STEP 3]
It is the momentum that I want to remove at once as it is, but I will peel it off carefully little by little using a dryer, heat gun, etc.
We make a gap little by little, insert a pick, etc. into the gap, so that the glass does not stick again.
Please be careful not to insert the pick etc. deeply into the main body.Cables and parts may be damaged.
Because there is rubber between the touch panel and the main body of the surface, please be careful not to deform or cut a thousand.
- [STEP 4]
If you plug it too deeply, you will cut the parts and wiring in it, so insert about 5mm as a guide.
In this way, if you do not peel off little by little, the touch panel will suddenly crack.
- [STEP 5]
The touch panel extends from the lower left side and the red area to the main unit, and is connected to the main base of the iPad (logic board).
There are four screws in the green mule part, so remove the liquid crystal display with this.
- [STEP 6]
It is the part connected to the main base and each cable and battery.
- [STEP 7]
Remove the three screws in the green mal part, float the main base slightly, release the battery and the base, and prevent the pick etc. from being interrupted between.
- [STEP 8]
Green is the cable of the liquid crystal display, and red is the nail which secures the cable of the touch panel.
Lift the black claws on top of each part, remove the lock, and slide the cable to the left to pull it out.
You can remove the LCD panel by removing the connector on the green LCD panel.
