Screens problems after replacing lcd and digitizer

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. :(

SOURCE: 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.

How to replace front glass on this unit


I need the model of your phone to find you a guide. A guide may not have been made for that device, but If not, I can find you a guide where the build and dissembly are identical. (Standard breakdown . remove battery cover. Battery, sim card, SD card, remove screws plastic cover. Use a guitar pick/opening tool to run along the seam to split plastic case. From here. Remove any metal shields (if any) to disconnect all connectors. Such as LCD cameras mic , vol buttons etc. Once freed of connectors remove screws holding logic board down. From here you should be holding a front "clip" just glass. LCD. And digitizer. Depending on your part.if its a complete front clip. The just follow steps in reverse on new front clip. If it's just the glass. You will need a hair dryer or heat gun to heat up glass and make adhesive loose enough to separate the glass from the frame. Once separated . follow steps in reverse. Take lots of pics during disassemble to remember location and order )

Half of the iphone screen is messed up


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. If it is an iphone 3 or 3gs you can buy the LCD screen seperate to the digitizer and is straight forward to replace yourself but if it is a newer version the LCD and digitizer comes together and is alot more difficult to replace. 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.

LCD screens


No you cant change the glass on the panel it is a sealed unit.The lcd panel is the most expensive part of the tv to replace and usually cost more than the tv is worth. LCd panels do go bad after years of service. some times a digital board can cause picture problems but from your description it sounds like the LCD panel. It may be time for a new set.

EM500 replace touchscreen


They are in fact very easy to replace if you: 1. Are very careful not to damage the other parts 2. Can find a replacement Understand that the screen is actually two different components, first there is the digitizer which is the part that senses your touching the stylus part. It is a clear glass plate that sits in front of the color lcd unit (the other part). If only the glass is broken, then replacing the digitizer is a cinch. If I remember correctly, the digitizer on the EM-500 is the same as the digitizer as on an E-125. You'll have to check to be sure though. Anyway, it is not too hard, just needs steady, careful hands...and it helps to have a little experience taking these things apart...
