Question about Apple iPhone 4S

1 Answer

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

I ordered a replacement kit that had the front glass lcd and digitizer and was so careful when I replaced it but when I put it back together I get a white screen with a black smudge on the top left of the screen and lines running across it. I took it completely apart removed the 27 necessary screws, checked to make sure the lcd and digitizer cable was not being smashing between the front assembly and base and still the same problem!!!!! I replaced the same thing on my sons Black IPhone 4 with no problem. And yes the two repair/replacement kits were specifically for the right phones. One for the 4 and the other for a white 4s. What could I have done wrong? Please help....I have no phone now. :(

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

Can a screen be replaced on a hannspree 10.1 tablet?


I replaced a broken display screen on an iPhone4. I ordered the
screen/digitalizer from Amazon for 16 bucks and it came with a number of tiny tools for the equally tiny screws and fittings.. It took me three hours of tedious labor to get it apart, to connect the screen/digitalizer (some wires with multi-connectors on the ends that are attached to the display) and put it back together. I used 15, numbered cupcake pan, paper liners to keep all the tiny parts in their proper places. I downloaded 25 pages of instructions from the Internet and printed it out as a repair manual. Bottom line, it worked and still works like new.

If you can find a screen/digitalizer for you device by Googling it and if you are handy with small items repair give it a go. But, be sure NOT to order just a front GLASS as you need the combination of display and digitalizer. The front glass thing by itself is a rip-off.

I think the biggest problem you might face is the repair *manual*. Unless some kind soul has spent considerable time compiling one that you can download, I don't think you will have any success disassembling the unit and getting it back together without breaking something else in the process

Shakey screen and lines across it after 4s screen replaced


Most likely you just got a bad part. As long as you didn't apply too much pressure when putting the screen in, then it's probably just a bad part.

Screen replacement


Is it the front glass/screen or is it the digitizer (main touch LCD screen)? If it's the first layer of glass then you can find kits online like E-Bay very cheap and Google instructions on how to do the replacement. I've done several and it's easy but follow instructions carefully.

Okay try this, ive been doing this and making a TON of money on it recently... go you youtube and search for iPhone 3g (or whatever kind you have, 3g,3gs,2g) digitizer replacement.

you can go to ebay and search for iphone 3g digitizer and it will come up with tons of links to buy them, order one, its about $20 and then put it on like said in the youtube vidoes... i dont suggest using Direct Fix's or PDAParts.com's video...

Basic instructions,
take out two screws on bottom of phone,
take a suction cup the the glass of the phone and pull up,
once inside look for where the cables connect and disconnect,
unscrew 6 screws and CAREFULLY pull off the LCD,
go ahead an rip off all the glass from the plastic frame,
replace with new digitizer (glass),
and put LCD back on,
re-assemble and put screws back in the bottom (dont forget to plug cables in),
power up iPhone,
you good! (:

this will only work with iPhone 3g/3gs

original iphones your kind of just stuck with a paper-weight

Touch screen cracked - can it be repaired and how much will it cost?


Okay, first post was just a test to see if I could post before typing all this out.

This is for a Garmin Nuvi 760

First, you can find a new touch screen on E-bay for about 10 dollars. The LCD+touch screens are about 60. If you just cracked the screen but the display looks fine, you can just replace the touch screen.

Now, for do-it-yourselfers. To open the back of the case, there are 2 small torx (star) screws on the back to remove. If you don't have a torx driver, sometimes just the right size eye-glass screwdriver can fit but be careful not to strip the heads. Once those are out, you need to seperate the back casing from the front. I used an old credit card to pry gently with all the way around until it pops off. Don't force it, just be patient, it will come off.

Next, I recommend unplugging the speaker and battery so you can put the back aside for more room. There are 4 more phillips screws on all 4 corners of the circuit board. Take those out and the board comes out relatively easy. Don't force it. Once it is loose, there isn't much room to play with because of the ribbon cables. The large one is the LCD, the 4 pronged one is the touch-screen. There is a lever that lifts up and secures them in place. I got away with leaving them connected, but they are fragile and easy to tear. Next is separating the silver plastic part of the case from the black front that goes around the screen. I pried a bit with an eye-glass screwdriver around the area where the earphone jack and memory card go in. Again, using a credit card to pry all the way around is best that it won't leave scratches. Don't force it, just be patient.

Once you have that off, remove the screen from the case. I did it by pushing with light-moderate pressure all around the edges massaging it out. The touch screen and LCD have a rubber/leathery thin tape going around the perimeter. On the front, I got under it with an eye-glass flat head screw driver and slowly worked it around until it was free, being careful not to tear it. On the back, I used a razor-blade to un-stick it from the LCD, but be very careful not to damage the LCD screen if it's still working. The goal is to get this off in one piece. Once you have that off, there is the LCD and touch screen with double-back sticky black tape holding them together around the edges. I used a razor-blade. VERY CAREFULLLY separating them. Once that was done, I carefully scraped the remainder of the tape off the LCD which was un-reusable. I didn't know what to use for putting the new screen on since I didn't have that special type of tape, so after raiding my tools, I found some rolled butyl rubber for installing windshields. I cut small pieces of this off and put them around the perimeter of the new touch-screen (VERY THIN) in the same place the old one was, as if I was installing a real windshield. This took much patience, but in the end it worked great. Before putting the new touch-screen on the LCD, I blew it off with some compressed air, being careful to never leave a fingerprint on it while working on it. After putting it on, I pressed softly but steadily to get the rubber to even out so there wasn't any high points. Then, I replaced the same sticky tape that went around the perimeter of the 2 screens the way it was. It wasn't as sticky, but I made sure it was in place and it kept there by the pressure on the sides of the screen casing. Make sure you get it on right, because I think it's there as a shock-absorber so that the screen doesn't break as easily if dropped or jarred. I plugged back in the LCD screen into it's corresponding place on the circuit board and closed the tiny lever that secures it in place. Then comes putting everything back the way it was in reverse order. Be careful and go slowly, I ended up accidently pulling the ribbon cable out for the LCD and Touch screen and had to go back and reconnect them. This is a good time to attach the battery and turn the GPS on to see if you have all your connections made securely before everything is fully together. Put everything back together in reverse order, remember, if you have to force it, then don't. Don't forget to hook the speaker back up.

When it's all back together, if the new touch-screen doesn't tap where you tap it, you can calibrate it. This can be done by turning the unit off, then turning it on, then IMMEDIATELY switch it to the right(lock) position before it boots up and hold your thumb on the screen for about 30 seconds. There will be a callibration routine that will tell you to push dots on certain parts of the screen. If you do this with a stylus, it will probably be more accurate.

Now hopefully, you will be more careful and not drop your nuvi again. I hope this helps.
