Common mistakes while replacing iPhone screen -- case 5 connecting & removing connector error

after successfully open the iPhone .you might be so excited .and be less careful while removing the plug .the wrong way to removing and connecting the plug & connector would easily got the screen damaged .or furthermore ,got logic board connector damaged ! if logic board connector got damaged ,even you have new screen .you already can do nothing with your iPhone .

when removing the connector ,do not use "hand" to pull them ! instead ,Use the flat end of a spudger, or a fingernail, to disconnect the digitizer cable by prying it straight up from its socket on the logic board.

and most importantly .When reconnecting the cable, do not press the center of the connector. if the position is correct ,you don't need too much force .Press one end of the connector, then press the opposite end. Pressing in the center of the connector can bend the

component and cause damage.

Common mistakes while replacing iPhone screen-- case 3 wrong screws size

after you disassemble your iphone screen .if the screws are stored and look like as below picture.then you will be in trouble!

there's a lot of different screws size in iPhone ,they might be differing for only 0.1mm.

for our common sense ,interchange some screws should have no harm .but that's wrong !

Using the wrong screw in the reassembly can result in permanently damaged parts, including destroying the main circuit board, other times they become a nightmare for the unfortunate technician who has to service the phone the next time.

it's also possible to penetrate the back of Screen directly with physical damaged you can observe right away. so please must keep track of "every screw" !

below might be a good idea to help you keep tracking of them. where each screw goes you can draw a rough diagram of the phone on a sheet of paper and stick the screws down in their approximate locations with tape.

Common mistakes while replacing iPhone screen-- case 2 Forgot to transfer front proximity sensor / camera ring

Usually new beginners don't even know what they are and forgot to transfer them to new screen. Bonded to the original display units is a small clear plastic guide for the face camera, it stops it moving around by keeping it properly aligned relative to the hole in the screen.

When the plastic ring isn't transferred with the new display it can result in the camera showing strange blurred edges or pointing in the wrong direction or proximity sensor not working ( while you listen to phone . the screen won't light off )

Common mistakes while replacing iPhone screen-- case 1 Forgot to peel off the plastic

Sometimes this is just a forgetful thing, sometimes it's laziness, often it seems to be that the repair person isn't even aware it's supposed to be removed.

Leaving the plastic on isn't so bad if the little tag is cut off, sometimes it's done to gap the display away from the chassis slightly. Unfortunately if the little tag is left attached it causes a pinch and crush problem to the edge of the delicate LCD display and frequently permanently damages it.
