Phone slammed on Ground.. Is mother Board dead? - Galaxy S 4 Q&A, Help & Troubleshooting

I Received a Phone that was slammed on the ground top part of phone was bent.. Screen cracked and wont turn on ..front camera and proximity sensor broken also...
Purchase new lcd and digitizer and installed it and phone still will wont come on...
Is there a way i can check if the motherboard is dead???

Is think the motherboard is still working when the PC recognises your phone. Not sure, but I think I'm right! At least worth a try

Obviously it wasnt put back together correctly, most likely the ribbon cable is either loose or broken.
LCD ribbon cable is either not pluged in fully or the cable is ripped

[Q] Replacing Nexus 4 digitizer (but not screen)?

I got my Nexus 4 (very) wet, and it destroyed the battery. I've replaced the battery, and almost everything is fine, but the bottom part of the screen doesn't register touches. I now can't hit back/home!
Is it possible to replace the digitizer without replacing the whole LCD and glass? The LCD and the glass are absolutely fine, and really quite expensive, so it would be a bit silly to chuck them away.
No, the digitizer and the screen are connected (might even be the same thing) so you would have to buy all of it, sorry

For this model (and for 99% other) LCD screen and digitizer is piece - let's say - a hamburger. It can be changed only as one piece.
AND - if phone was wet You can`t know for sure that digitizer is that part that must be replaced. Maybe there is problem on motherboard that causes this.

[Q] A Bit of Help please! S4 Wont Turn On

Hello,
Unfortunately, I am in possession of a Galaxy S4 I9505 which has been dropped into water. It doesn't show any signs of live except a single vibrate after around 6 seconds of holding down the power button. Drying the device in rice hadn't helped, so I upped the ante and submerged the motherboard of the phone in ethanol as per the instructions of a revive-a-phone kit and left to dry for some time. After this it still didn't work, so I assumed that the motherboard was simply too damaged.
I had managed to buy another used phone (working, but with a smashed digitiser) and swapped over the motherboard from that one onto the new. Unfortunately though, it still doesn't work. I have disconnected all of the connections to the motherboard (the externals that is, camera etc) with the exception of the video cable and it still does the same thing.
Is there anything I am missing? Or does it look like the LCD is at fault? If so, would it be in any way possible to exchange the LCD without replacing the digitizer too?
I am sorry for the drawn out question, but any help would be very much appreciated!

AFAIK, digitizer is connected with LCD by some glue...
However, putting the phone into ethanol itself could potentially kill the phone, as it is a good solvent for any acrylic based paints, isolations etc...

I think the idea of it is that it will dissolve any deposits from the water that might be left on the motherboard. I had used it to some success on another phone, but no luck this time. In any case, it was only the motherboard that was submerged, not the entire phone as the guides would suggest, so that couldn't be the problem.
Agh, I see what you mean. I have gotten time to view some videos and it seems it is neigh on impossible to remove the screen from the digitizer. I bought a second phone with the only piece I needed being broken!

lg g2 screen damage

Hello guys i have a issue. my phone fall down and now the digitazer broke and the touch is not working. i found the same phone in realy low price because of water damage... its not power on. my question is to buy it?? is the lcd damaged from the water or is possible to work on my phone? thank you.
No one can give you a definite answer because you do not know if it will work unless you test kit with a working motherboard. There is a 50/50 chance it could or could not work.

Capacitive buttons replacement

Hi!
I have a Samsung GALAXY s7 and 4 days agof my capacitive buttons stopped working after i submerged the phone in water, I sent it to samsung so they would fix it but they sent it back today telling me that the warranty doesn't cover water damage. So now I was wondering if there is anything give can do to fix my capacitive buttons, is there some way I can replace them? If yes how and where can I buy them?
Also before all this, i had another problem with the phone, it's memory was damaged and the OS had problems, I made a thread about that too, but ended up sending it to samsung cause I couldn'the find any solutions. Right after the capacitive buttons stopped working 4 days ago I noticed that the back part of the phone was't sealed, I could separate it with my fingernail, so I think that the guys who changed the damaged memory forgot to seal the phone properly and that's why it got so damaged after 20 seconds in water. Of course now after I sent it a second time for the capacitive buttons they sealed it properly now, so I have no evidence of this.
