Samsung U700 disassembly problem

I want to change the flex cable on my U700 but i dont know how to disassemble the slide. I have taken everything off the back of the phone and the slide is only thing that is keeping me away from changing the flex cable. I have service manual for this phone but there is no precise instructions on how to do that.

Remove the large white identification label from the rear of the slide and you will find 6 small screws. Once these have been removed you can seperate the the slide and access the flex cable connector. The service manual for the SGH-U600 which shows full disassembly instuctions can be found here.

Samsung SGH J-750 has no sound, no ringtones etc when the slide is flipped on, but when it is closed, you can't hear any sound. Is there any settings to activate its speaker again when the slide is open?


Hi,the bitter truth is that there is no settings that activates the speaker of the phone when slide open or closed,the problem is from the flex connector cable which is associated with the sliding of the phone,the flex cable needs to be replaced,However you have to disassemble your phone to get the flex cable.
You can get a well detailed description of how to disassemble your phone and how much the flex cable costs at;www.formymobile.co.uk
Thanks and take care

What is the possible trouble of my samsung sgh u-700, the screen only shows blank and sometimes the features appears but not in a normal appearance,,, it appears scattered and moving in different direction...


I think this a problem related to the flex cable that connects the main phone body to the sliding screen. Over time the flex cable wears down as it slides and results in a whole range or problems such as: display acting weird (eg. mirror-image and inverted colours), speaker not working, off-button not working etc.
Flex cables are cheap to buy on ebay (a few dollars) and there's internet sites that show you how to open the phone and replace them. (google: samsung u700 replacement flex cable)

Volume buttons won't work, camera button wont work, and speakerphonew button wont work. Happened out of nowhere. Cannot lower/raise volume on side of phone, only vibrate works.


Hello.
Welcome to Fixya's Community.
These problems HAve been related to a damaged flex cable.

This is the cable which in the U700 connect the lower part of the phone to the lcd part (with the screen, speaker, camera and touchscreen buttons). All the data such as screen images, camera pictures, speaker sounds pass through this cable from the main board which is located in the lower part of the phone.

Unfortunately, each time one opens the phone, the cable slides between the two part of the phone. In the long term, as the cable is thin and soft and this movement causes frictions between the cable and the parts, the cable consumes itself. the damage of the cable could results in weird effects on the phone.


In order to fix that you need to replace that part.
its easy.
just take the phone apart and locate the flex cable and replace it.
believe me you can do it yourself.
  • The Flex cable of your phone cost 3 $
  • A phone repair shop will fix that for 25 $

see if you can find it on eBay.
remember its SCH-U700 Not SGH-U700 there is a big difference.

Good Luck

Samsung a950 main screen display is backwards and upside down


My Samsung U700 had the same problem (display went back-to-front and colours all reversed and low-res.) It seems to be a problem with the flex cable (the cable between the main phone body and the sliding screen) wearing down and screwing up the data being carried between the display and the phone. Flex cables are cheap to buy and there's plenty of info online showing how to replace them yourself. Good-luck. Google: samsung u700 replacement flex cable
