Hi
i bought a used note 4 that had a badly damaged screen i also had a note 4 with a dead motherboard so i removed the screen from the dead phone and applied it to the screen damaged one and everything works fine after id booted into recovery to remove the previous owner security.i then setup the phone connected to wifi etc...but upon testing the camera's i noticed the flash not working so i checked the settings to see that it was enabled still no joy i then downloaded a torch app but that didnt work either so i updated the phone to 6.0.1 ota and still no joy...i have not reassembled the phone as i feel the problem could be board level i put a multi meter in continuity mode on the flash's contacts and it lite up showing me that the led is working but i dont know where else on the mobo to check as i cant see any tracks leading to the led flash....Any idea's ?

After upgrading to WM6, every works perfectly. But then, it seemed randomly, the display is blank/ all white, but I can the phone is still functioning, because i can tap on the screen and get the tap sound. Soft reset and hard reset doesn't work. I'm doing the hard reset blindingly since the display is showing nothing, guessing the key push (i pressed record-camera 3x then mail button). I'm pretty sure it did the reset because after about 30 secs I get the beep that comes on when the screen is showing Tap to setup your device.
I figured it might be a loose lcd cable, but if go into the bootloader, power+record+reset. The display works fine! Showing Serial V 2.07.
I took apart the BA anyways and made sure the lcd cable is firmly attached. It didn't work.
Sometimes the phone would go back to normal randomly, or if I let the backup battery drain, but not always. When it goes back to normal, the clock is always reset to 2004 12:00 AM.
Can anyone help me? Is it possible to have a loose LCD connector which won't be able to show normal display, but can show the bootloader normally? Or is it caused by something else?
Here are other things about my BA that may or may not be related to the problem:
-Can't use DOC_Repart to resize storage, I'm getting the FL_IOCTL_FORMAT_PHYSICAL_DRIVE failed as described here http://forum.xda-developers.com/showthread.php?t=255585
-When upgrading the upgrade program can't detect my current OS version (showing blank under "Your device is about to be update from:"), but otherwise the upgrade works fine.
-I tried Helmi R0, PDA Viet , and xplode's 6.00 roms. They all give me the same problem
Thanks.
I am also experiencing the same issue... currently phone is at white scren, but using My Mobiler i can see my desktop and see that the phone is fully functional, just white screen so cant use...
Mine too. I can see the display working perfectly using SOTI pocket controller pro. So the phone seems to be functioning except for some reason the screen is showing all white screen.
cubangt, are using an extended battery or the standard battery that comes with the phone?
Have you tried flashing with a different rom??
Sorry, I fear my message won't be useful at all for you, but I'll post it just for the record. I hope you can find the solution to your problem anyway!
My BA now can't show anything but a white screen because of what I think is damage to the screen cable (while sliding the display the backlight goes on and off...).
But the cable is not loosely connected, it is sort of strongly bent at one point, and maybe some contacts got kind of cut. Now it does not work anymore, but some time ago switching it off and the on again used to do the trick: the display would be readable again (even though with annoying colours, stripes and so on). I don't think this is your case, but I'd like to warn the newbies like myself that they should care not to lose any piece while changing the LCD on their BA: I think I probably forgot about some sort of protection which could avoid damages to the cable in its movement.
As for the missing version number when upgrading, the same has always happened to me.. I think.
Ok, sorry for my English, I would have had some troubles with exposing these few silly things even in my mother tongue... bye... and good luck.
I tried 3 different WM6 roms. And if I remembered correctly this also problem also occurred for a brief while I downgraded to WM2003SE while trying to resize the storage(which failed).
Yeah I'm not sure if mine is a hardware problem, since I can always go into the bootloader and the display works fine there.
I have new info to add though. I found out I can reliably get rid of the problem by draining the backup battery. Now I have a new question, since draining the battery takes a while, is there a way to reset the phone as if the backup battery is emptied (and return my display to normal)? If I can find a way to simulate this, then I can actually use my phone again, even if I have to do this once a day.
Obviously soft reset doesn't work. And I don't wanna do a hard reset either. Maybe the experts here now what kind of data is reset when all batteries are completely drained.
Thanks for the help
hmmmm
quick thinking.....i was working on my phone tonight and came across this thread.....if not grounded properly it could be that you statically fried a component in the process?
Hello all,
My rooted Galaxy S4 GT-i9505's display stopped working. It just so happened when I took my phone out of my pocket. The last app I remembered using was Whatsapp and I did not mess with any settings before that.
Powering on and off this phone feels normal with vibrations but there is no display and the Samsung boot animation does not show. Calling to this phone works, with vibrations. Touch does not seem to be working as I tried to unlock the phone using pattern lock and there is no feedback. I am also able to detect the phone in my laptop but unable to access files as I am unable to unlock it.
I tried booting into Recovery/Download mode but it does not show anything. I have also pulled out the battery numerous times but the display still doesn't work.
Very looks like time to repair that phone, there are many phones likes that with board problem, just make sure LCD is not cracked, the bring it to local repair center do replace one component on the PBA.
I bought an i9505x from eBay, before realising that the "x" signified a shop display demo model, which has the SIM socket disabled.
I then bought a working, unlocked i9505 logic board from eBay to replace the dummy one.
I received both and the demo unit was in immaculate condition, booted and displayed "Galaxy S5, Live Demo" on splash screen startup. Everything worked apart from SIM of course. All sensors, camera, WiFi... everything apart from mobile networking.
I then swapped the demo board for the full logic board (and added the thin antenna cable that runs down the side of the screen as this wasn't present on the demo phone). The phone booted and received telephony and internet from both the giffgaff and three SIM cards I tried in it. Everything else worked.
I rooted/CWM'ed it and upgraded the ROM to 4.3 or 4.4 (can't remember which one) and it worked OK for maybe two days and I went to work. When I got back from work my girlfriend said it had been displaying green lines and dots on the screen so she turned it off and put it on charge.
I had a look and there were intermittent rolling pale green lines quickly moving up and down the screen on boot, with a few dots the same colour at seemingly random intervals. After leaving the battery out for 30 mins and putting on charge for 30 mins I managed to get it to boot into ROM and all seemed well until I tried to reboot and the lines/dots happened again, with the dots getting worse.
In a tiny font on the display it seemed to have a line of text, but as it was so small and scrolling about I couldn't read it. A couple of boots later and the screen is totally blank.
I've flashed a stock 4.3 ROM on it by guessing the download key combination, as there's no display for download mode. Odin responded correctly, showed a connected device and went through the ten minute flash process and rebooted the phone.
The phone now boots and makes the Samsung startup tune and once booted I get the volume adjust bleeps when I press volume up/down so I know the ROM has booted but the screen is totally dead. I even get the initial blue LED for a couple of seconds on boot.
I'm going to try swapping the demo board back in today to prove if the screen is dead or not.
If the screen is OK then could it be the GPU portion of the logic board?
If so, what are the chances of me swapping chips around? I imagine this would be an impossibly tricky job to do at home.
Thanks for reading.
How much have you laid out so far £££ ?
i have a n9005 ,, suddenly screen goes black ,, touch not working ,, but phone is working ,, i tried to remove battery and do every thing possible for 10 hours ,, nothing help ,
i thought that this is a software problem (xposed+gravity+xnote) something like conflict , but i can enter download mode ( ican't see any thing but with just volume keys) , i flashed a stock rom with odin ,, same problem ,, the blue led on and nothing on the screen not even SAMSUNG GALAXY NOTE 3, i thought that the lcd is dead ,, but i found a video that if the lcd dead the touch still working , and this not happen here ,
i tried another battery ,, but no hope
i removed sim and sd card ,, no hope
this problem happened before like 3 times ,, but i just remove battery twice or 3 times and it work again .
so what do you think guys ???
note: My phone is out of warranty (from foreign country) .
If the issue were software/rom related, the screen would work when in recovery or download mode.
Unfortunately it seems it is a hardware problem and you have to send the phone to service.
I would take it apart and check all connectors, not too difficult if you follow one of many videos on youtube. The fact that phone is working, but no screen and no touch makes me think it's something basic, like screen power supply or maybe whole connector is loose? if you don't see anything obvious, put it back and send it out then.
Hi i have problem with my s5 display, it starts going crazy like scrolling up constantly, when i use it and then switch the power button to shut thr display the phone does not power back up unless i remove battery, otherwise the two button lights only show.
Prior to this problem, it started when my mic at the bottom stopped working, and then the pinnacle point was when i unrooted my s5 and rebooted, immediately the colors turned to different tints of colours.
The next day it started going all fuzzy and scrolling up.
Took it to samsung but waa refused as i found out about the knox counter lol
I have my usb port dock part which im ready to replace on my mainboard. But what ia causing the funny display ? I can barely use my phone, the digitizer seems fine aa at times it works for like 5mins.
