Howto fix a phone with a spot screen?
The screen of a mobile phone usually contains two main parts, the LCD screen and glass.
The glass covers the LCD to prevent accidental damage and occasionally acts as a digitizer on touch-screen phones. Although the glass is easy to replace on many models of mobile phones,if the LCD of the mobile phone breaks, it is almost necessary to completely disassemble the phone when replacing it.
1. Remove the battery cover,battery and all cards from the device, such as a SIM card or SD card.
2. If your phone is a clamshell device, remove it from the screws on the back of the device and the screws around the LCD. The type of screw will depend on the manufacturer and model of the phone, but is usually a T4, T6 or #00 Phillips screw.
3. Use a pry bar to pry the case out of the device. Once it is determined that all of the screws have been unscrewed, simply insert the crowbar into any position between the two outer casings and then move the crowbar around the outer casing to pry the clip between the outer casing and the main body. Continue to remove the housing until only the control board and LCD are left and half of their respective housings.
4. Disconnect the control board from the LCD and digitizer if necessary. On most devices, you'll find cables from the LCD to the control board. Lift the connector to disconnect the cable.If you have a touch screen device, you must perform the same task on the cable from the glass to the control board.
5. Pick up the LCD to remove it from the case. On some devices, you must also smash the glass away from the LCD. In these cases, using a heat gun on the glass for about 30 seconds loosens the adhesive enough to separate the glass. Note that some devices, such as the iPhone, permanently hold the glass and LCD together. When you get a spare LCD,check to see if it contains glass. If so, you can skip the part to split the glass and LCD apart.
6. Place the broken LCD aside and install the spare LCD screen in the housing. Simply reassemble the device by simply reversing the steps to disassemble.
The Bottom Line:
If the black spot on phone screen spreading, you can replace the phone screen assembly separately. Since the replacement of the external screen requires a series of operations such as dismantling, separating, removing glue, and installation. In general, change screen by yourself is the most cost-effective way. But for many people, it may be a more difficult operation. You can also go to the Apple store for repairs.
