S7 Edge Black Screen / Blue LED Flashing
Hello, I have an S7 edge that does not work anymore and I would like to repair or have it repaired according to the breakdown. The phone charging and taking it: black screen + blue led flashing ... I tested all the manipulation with the buttons nothing ... from the phone and still in black screen there is not even the led blue . When I try to light it, nothing happens ... the phone is cold ... do you know where it comes from? Drums ? Load connector? Motherboard ? How to find the part that does not work anymore? I have data to recover in it

Hello, Does the Galaxy S7 seem lit even if the screen was off? Because it can simply be a HS screen in this case. It would be necessary to check if the layers of the screen are well connected also, in case there would have been a shock which has unclipped them. Otherwise, you have to change the screen. To find out if this is a charging problem, you must already test with another functional USB cable on another device, and see if your Galaxy S7 is recognized by your computer. If it is recognized, there is little chance that it is the charging connector (but nothing is impossible). In this case, by elimination, it would rather be the battery. And if this persists, even that the charging connector is no longer able to transmit the energy for the load. We must proceed by elimination. Afterwards, you always have the possibility to address a professional Captain Repair [/ url: 18xxgbh8] to limit the expenses and to identify the problem more quickly. Sincerely, Sandra

Hello, I have done some tests. I decided to change the battery which did not change the problem. So I change the motherboard (buy a hundred euro in China) and bingo the phone reboots. Without any data obviously but with the Samsung backup I was able to recover a good part. Hoping to help some, even if a motherboard is expensive, it's always less than a new phone.

[u: 1gsqfrq7] Hello, My wife has a problem with her Samsung Galaxy S6 this afternoon. She took it out of her pocket to check something, she realized it was hot black screen with the Back key and icons (those between the home button) turned on. The blue LED is fixed. Can not restart (or turn it on) and the "Flashait" screen. I searched in English and French on google, but can not find a track on this screen that "flash". If left unloaded, it quickly becomes very hot. Manip Power + Button down has nothing given, Power + home + button down either.

Hello, Before thinking about a hardware defect, we should try a complete restoration of data via the Samsung software [url = http: //www.samsung.com/fr/support/smartswitch/: 3py15czm] Smart Switch [/ url: 3py15czm] (thinking about saving its data) to eliminate the hypothesis of a software defect or an application that would create a conflict. Otherwise, check that all components are properly connected, including the display and the battery. In case of overheating, this may be due to a fault in the battery. And if the phone seems lit when it displays nothing, it may be linked to an HS screen. Sincerely, Sandra
