You just broke the screen on your iPhone 4. Your expensive phone is now a useless lump of circuitry and you don\'t have the money to replace it or to have it professionally repaired. That\'s quite a predicament. Though a lot of risk is involved, this repair can be done at home. Of course, this should only be attempted as a last resort as any warranty you may have had will certainly be voided. If you\'re brave enough to give this a shot, you can get the replacement parts online.

Turn off your iPhone and use the SIM removal tool to pop your SIM card out of the right side of your device. This tool can be purchased online. Remove the two small Phillips head screws from the bottom of the phone to free the back panel. Slide the back panel toward the top of the phone and pull it straight up and off. Set the back panel aside. Use the screwdriver to remove the screw that holds the battery connector to the iPhone motherboard. Pop the connector up and remove the battery by pulling on the clear tab on the left side of the phone. Remove the black shield on the top of the phone by removing the five screws that hold it in place. Be aware that two tabs on the shield work like hinges. You will need to pull the top up first and then slide the tabs out on the bottom. Remove the small black shield from the left side of the battery compartment by removing the two screws that hold it in place. The small shield will pop right off revealing a connector on the motherboard. Use the plastic prying tool to pop the connector loose. Remove the small vibrator from the top right corner of the iPhone. Remove the two screws that secure it to the circuit board and pull the device out. Unplug the five circuit board connectors from the top of the iPhone using your prying tool. The three smaller connectors must be pulled up from the top, while the two larger connectors on the left must be pulled up from the bottom. Remove the iPhone\'s camera assembly by unseating the connector from the mainboard and pulling the device out. Pull the ribbon cable on the right side of the phone up as far as it will go. This will reveal a screw that secures the speakers in place. Remove this screw as well as the screw at the left of the speaking housing. Carefully pull the speaker assembly up to reveal a wire connector on the motherboard. Unplug this connector and set the speaker assembly aside. Remove the screw on the right side of the phone next to the black moisture sensor as well as the screw holding the circuit board in place near the top of the phone. Pull the motherboard out of the phone and set it aside. Remove the 10 screws that secure the iPhone screen to the case. Three are on the side panels and one in each corner. Pry the screen out from the front of the device using your prying tool. Replace with your new screen and reverse these instructions to reassemble your iPhone.

Replace a broken iphone 4 screen


This is not easy. You can buy one fairly reasonably but it is not an easy thing to fix! You Tube has instructional videos but be prepared to take out many tiny screws and plugs and then put them back in the same spots! If you can find one-take it to a repair shop; it's worth the extra money to have someone else do this.

How to fix a i phone 4


Hello Anonymous
This would probably be a good opportunity to take the iPhone4 into an Apple Centre and pick up a cheap upgrade to an iPhone4S at least. (faster processor & better camera). Your phone is getting outdated and Apple offers a relatively cheap way to get to a better model. But.... if you thing your savvy enough to attempt replacing the LCD unit, here are the instructions. Just remember... you can't take it in to Apple if your attempt fails.
Replacing the display assembly will give you a new front glass panel, digitizer, and LCD. The LCD is adhered to the glass at the factory and the two parts are not separable without damage.

Broken iphone screen


There WAS A YOUTUBE video on how to do this as I bought an iPhone off ebay with cracked front and back. I was able to replace the back because that was fairly simple, but the parts are very small and you need a special tool to even take it apart. Replacing the front didn't look so easy. You pretty much have to take the phone apart which would be the easy part, but you'd have to remember what cables plugged in where and what screws of different sizes went where. You're better off taking it to a place that does this repair often!

Screen is white but can barely see like the bell that showes when you turn on and off vibrate and a smudge on screen


Put the old one back on and see if you get anything. If not then it is the kit that is bad.
