Question about Apple iPhone 4S

1 Answer

Shakey screen and lines across it after 4s screen replaced

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. :(

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.

How do I replace touch screen on my iPhone 4s?


i replace screens for a living, its a little fiddly but if you are mechanically minded and methodical you should be ok. look on youtube, there are loads of video's how to do it. do not just buy a replacement digitizer, buy a complete unit (digitizer, lcd and frame) you need a lot of practice and the right equiptment to remove just the digitizer because they are bonded to the lcd and are easily damaged. i'm in the uk and i use a company called partek. if you buy from ebay please do not buy the cheapest screen you can find, they will last about 3 months then fail. type in iphone 4s genuine lcd. thatway you will get a good quality unit.

Replace screen


If it was caused by your phone taking a knock then you are probably after damaging the LCD screen, iphones have 2 screens, 1 is the digitizer (touch sensor) which is a see through plastic sheet attached to the front glass of your phone, the other is your LCD screen which is behind the digitizer which projects the actual picture. You buy the LCD and digitizer together for the 4s, it is not possible to replace the LCD alone so don't get caught buying just an LCD on the internet, it is a difficult repair if you are not used to repairing phones. If you plug you iphone into your computer and itunes recognises your phone it is more than likely your LCD needs replacing. Have a look at a repair video on the internet so you can see what is involved in the repair and you can decide if you think you would be able to do it yourself.

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.

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.

My nokia c5-03 is fell down now 4 black lines occurs in my display wt is d solution sir.


Broken front panel

Take a deep breath and see if your iPhone will turn on and operate normally. In most cases, the iPhone is still functional but now a cosmetic disaster. Unfortunately, the iPhone 4S' front glass and LCD are fused together and must be replaced as one piece.

Broken rear panel

Apple did not grace the rear panel of the iPhone 4S with the same high-strength glass as the front, so fractures are much easier to come by on the backside. If your rear panel is smashed, you must replace it with a new one. Before attempting this repair, though, make sure you have the correct screwdriver.

God bless you

Broke screen iphone 4


No. The digitizer and lcd and everything is one piece in the iphone 4. You have to replace the digitizer and all. Which means you do have to take the iphone apart.

When I take a photo there are lines across the screen, also when I look at them it says read error.. ?


A CCD problem would explain the lines on your pictures and the lines on the LCD (since the CCD is used to feed the live image).

If seen on both your pc monitor as well as the camera's LCD then it's likely a CCD issue and it's no wonder that it will be more expensive than buying a new digicam. This is why you need to be exceptionally careful when taking care of your camera since most are uber sensitive to being damaged by the slightest miss-handling.

In order to correct this issue, the repair facility needs to replace the CCD. This is not something you may do on your own.

Iphone 3G fell, screen intact but, now when turning on


Find a repair shop...easy fix 10-30 mins max. Parts needed are lcd screen/digitizer. If front glass is cracked then you will have to replace that as well. I just had mine done and it is perfect. 120 dollars CDN. You can also order the parts online and attempt the job yourself....youtube for demonstration, but only if your feeling up to the task.

Good luck and hope this helped
