Hi,
Today, my Uni suddenly turned off. When I started it again, it displayed the first splash screen, then changed to the second one and didn't go any further. I can turn the display of using the on/off button, but when I turn it back on, it only displays the second splash screen again.
Now I found this topic ( http://forum.xda-developers.com/showthread.php?t=259003 ), but I am not really sure, whether it adresses my issue or a different one (being stuck in bootloader mode, not on splash screen). I will probably read through it tomorrow (don't have much time now), but if someone could at least tell me whether it might help me solve my problem or give me a solution directly, it would be awesome. Oh and btw, is there any chance of saving my data from the device?
Thanks a lot!

Hello all. First let me state that I rather not make a thread to ask help on a problem that seems to have happened to a few owners, but my knowledge as to how I could resolve the issue is severely lacking..
At some point today my phone was ringing but the screen would not show. I thought about taking the battery out and turning it back on but there would be no HTC, Bootanimation, anything. It was Just a black-lit screen which responds due to tactile feedback and the four touchkeys light up as usual. At first there was an odd sound that would play after a few minutes so I decided to charge it but again there was nothing. Even tried to access bootloader with -Vol and Power still no screen.
I asked a friend of mine to call my phone to see if it would ring but they said it instantly goes to voicemail as if my phone was off. Note that I WAS SURE IT WAS ON.
Adb seems to work with it as it seems whatever I need to do I have to do it through there.
G2 rooted with gfree method
CM7.1 RC1
Clockwork Recovery
Again i am sorry if I bothered those with posting something others would think is "too common of a problem" as I have no experience in fixing this issue. Plus I would like to try any option available as I would not like to try and have my phone replaced (because of the risk of discovering root and obtaining a G2 with stock gingerbread which is currently not rootable)
Please help..
It sounds like you're suffering from some sort of hardware failure. You need to send your phone in for repair/replacement.

Same issue here...
I'm facing the same issue, when i try to unlock the phone (power button or trackpad) the screen lights but stays black, and the buttons are also backlit. I have to lock again with power button and unlock again to get to the actual screen.
It first happened a few days ago, and since i didn't reboot/restart in weeks i tried to reboot but the same issue comes back.
then i shut it down, pulled the battery and then back, and restarted: the phone goes directly to that black backlit screen, i tried several times and tried recovery with no luck, so i thought my phone was messed up although i did have some haptic feedback, well in fact the phone was actually booting, but just not showing anything else than the backlit screen; i waited a minute or so to the booting completes (still shows nothing), then i lock/unlock the screen again and there it is, asking for the pin code.
I tried to go to the recovery again to try to wipe dalvik-cache, i know for sure it goes to recovery, but with a totally black screen, not even backlit this time; the trackpad is too sensitive in the recovery to just blindly navigate in the menu, so it is not useable at all.
Then i had the idea to go to Rom Manager, i reflashed the rom from my sd-card, and enabling wipe dalvik-cache, which worked (all through a black screen). After a few minutes i "felt" it rebooting (vibrating) but still back to that black backlit screen, and i locked/unlocked it again and back it was asking pin code...
I also tried to roll back recovery to 3.0.2.4, since i remember i updated it a few weeks ago, but still the same issue.
I don't know what else to do without accessing the recovery, i wanted to try another kernel, or remove the trackpad wake... is there a way to do it via a script? I guess it's what Rom manager does...
Next step will be a total wipe, but i need to make some room on my sdcard for backup purposes first...
If anyone has an idea to sort this out, i'm highly interested...
I'll try to get a logcat, maybe could give a hint
Edit: Virtuous sense 2.0.0 (used it with no issue since it came out, could it be a hw issue?)
Edit2 : attached logcat
Is the pin screen differant than the usual one ie white number keys? If it is that's the sim lock screen you need to call the carrier to get the code or find out the default. Or just get a new sim lol
nah it's the 4 digit pin code, i didn't lose it btw, it's still working and i can use the phone, but i have a black backlit screen whenever i want to wake the phone, and thus when i receive a phone call, i don't know who it is and i blindly press/swipe the screen to answer, because if i want to use the same trick of locking /unlocking, it doesnt work as the lock button is also used to reject a call...
Maybe rip and reinstall the phone app?

I have the same exact problem as this EXCEPT, it's intermittent. Sometimes when I wake the phone I get an all black but backlight screen, and other times it's fine. I'm on CM7.1.
But a superwipe and reflash will probably fix it. Also don't restore system data on TB
I know i still can use wipe data + cache + dalvik through rom manager, and i always used to superwipe before switching roms, but how can i do that now when the recovery is all blacked out?
can anyone guide me to a script or something i could do while the phone is active, to tell him to reboot to recovery and flash that superwipe?
anyway i'll try the regular wipe and keep the thread updated

On my side if i leave the phone locked more than 30 seconds, it happens 100% of the time; also I noticed that now the backlight blinks 2 or 3 times (1 second blinking) when locked, first a few minutes after locking, and then randomly, about 3 or 4 times per hour; I guess it's getting worse;
I've read on another thread that it could be video cable getting loose, but since mine is still under guarantee, i won't open it right now just to check, if i can't fix by wiping / superwiping (when i know how to), i'll use that guarantee, which is one month left (lucky me)
EDIT: one other thing that makes me think it's no hardware, when the black screen appears because of a phone call or a message, the ringtone and notification sound are both half as loud as they should be, this is all really strange
after backing up my data, i reflashed the rom via Rom Manager, and I wiped data and cache (which equals to factory reset) this time: the first screen that should show the pin code numpad was already a black (backlit) screen!!
Also, thinking about it, i realised that the "flash rom from sdcard" menu in Rom Manager is in fact "Flash ZIP from sdcard": the zip doesn't have to be a ROM!!
So I tried flashing a new kernel this way, also some framework modifications (extended settings, removed TP wake, etc...) they all install Ok, but still this black screen...
Also I was about to flash SuperWipeG2.zip this way, but if it doesn't fix my problem, I will be stuck with a blacked out recovery, as SuperWipe wipes everything including /system; so if anyone has an idea to tell Rom Manager to flash two zips (Superwipe then Rom) i'll be willing to try, or a script to do that;
Maybe i'll have a look of the scripts in Superwipe and in the rom, and put both zips together... don't know if it's possible?
Maybe I'll try the Superwipe alone if I can get a spare phone, just in case...
Other thing:I used the phone's gps for more than 5 hours with the screen lit, and it never flickered even once; so it's hard to believe it's a screen connection issue...
Just to keep this updated, everything i did, including superwipe didn't change this issue, so i sent it back to the technical support (under guarantee) and I got it back today; the report that came with it says the screen has been replaced; so it was hardware finally...
Hi, i have same problem.. Black screen in recovery and during the boot. When the system boots, screen is OK. Sometimes i have also blackscreen when I want to use HW keyboard. I tried 4ext, reflash older versions of CW but still the same. I can see a screen through Android Screen Monitor and I can cotrol it. But phone is blak, only backlight. Can somebody say, how to solve this issue?
So, for other, if you cant see screen, you can use Android Screen Monitor for Windows and connect phone through USB and see a screen.

WAIT one minute... they don't care? where was I when this meeting took place?
I had this issue as well on a spare G2 I had.
The screen was just black but you could tell it was lit, hardware keys were lit as well.
The phone was actually my brothers and it rooted w/ CM7.
I ended up selling the phone as is on Ebay but after some research it was a failure in the hardware for the screen and I found extensive instructions on how to replace it that I didn't wish to do.
I never attempted to get it replaced and kind of wish I did now if they don't care about the device being rooted.
I purchased my G2 before he had his, and it's never had the issue so not sure what to think of it.

I used the same tutorial to change the LCD but after I put the new its just the backlight but nothing else... I will give it another go maybe and have a look again at those ribbon cables! I guess...

Thinking to buy this, it would be great if anyone could confirm that it would help "my condition" ?
THanks in advance!
In terms of cables, yes the flex cables are what you want.

Hi Guys,
i got a problem with my good old HD2: I flashed the SonyArcHD ROM on my device, it worked for a few weeks, but then, i did nothing, the screen went black. First i was able to "turn it back on" when i pushed it a little bit against the board, that worked for a few more days, but thet the screen went black forever. The background light is working, it even boots up(it happened when i just used it like elsewhen), i got even a haptic feedback from the unlock handle on the lockscreen, what means that it works perfectly "behind the black wall", but it shows nothing on the screen. Not even the bootloader. But the funny thing is, i never dropped it again, or damaged it anyways. It just hapened from nothing!
So has anyone a idea what i coul do?
Thanks, Jukpulfer.
Sorry for my badass english...
IMO you should check LCD to motherboard connector, maybe it is loose or dirty because of moisture/dust/whatever.
If no improvement(aka solved), I'm afraid you LCD is dying!
Hi guys. My almost brand new Samsung Galaxy S4 has just stopped working.
I was doing homework and one of my friends text me I look at the text and lock my phone screen and that was the last time I saw my screen working properly.
I later tried to turn on the screen but I had no luck, the screen wouldn't show anything, it was just blank but surprisingly it recognised my touch and made the sound. I could unlock my phone and even turn on apps by guessing where I kept them. I could turn on music and it would work but the screen would remain completely blank.
My phone was rooted and it had the stock rom but it had a custom kernel which enabled over clocking to 2.3 ghz (Ktweakers kernel I think) but the limit was set to 1.89 so I don't that that was the cause.
When I restart my phone the screen where it says "Samsung Galaxy S4 GT-I9505", I think its called the splash screen? I'm not sure, anyways instead of it being black with white writing, its really weird and is bright white with very light white writing. This is the only time the screen actually works, and the other time it works is when you try to put it into download mode but both times the screen is bright white and everything is very light and faded. After the "GT-I9505" screen goes away the screen goes black the blue LED still flashes and you can hear the samsung boot sound and the phone boots up properly without the screen.
What could be the cause of all this? I have literally kept this phone on top of my head. I have done nothing to harm it in any way what so ever. I have never dropped it. From day one I had a thick case incase I bumped it and damaged it. Anyone else having this problem? Or am I the only one? Do you guys think I'll be able to fix this or will I have to take it back to the store?
Thank you!

U can try to go to stock recovery and try to wipe cache and see if it boots up
If u have custom recovery wipe cache / dalvik/ fix permissn and reboot
else u should download a stock firmware and flash it using odin it will work incase even after u flash a firmware and again stuck at Logo etc go to stock recovery and wipe cache and reboot

Thank you for replying! I had cwm recovery installed but I reverted back to stock mod through odin. Now I am trying to wipe cache through stock recovery but the problem is that I can't see anything that I am doing. I am relying on pictures of the stock recovery. I know that my phone goes into recovery mode but it does not show anything on the screen. I am assuming I get stuck on the part where there are lots of no's and one yes.
Would It be possible if you could post a picture of that (The screen with all the no's and the one yes) because maybe then I can wipe the cache.
And I am already downloading the stock firmware, but it is taking forever because if the extremely slow internet. But the thing is that I don't see any logos, it boots fine but it doesn't show anything on the display. But I also know that the display is working because it still shows the "GT-I9505" screen. I'll post my progress here.

Okay so I downloaded the stock rom and flashed it with odin and it basically did nothing. Rather before flashing the stock rom, the splash screen would show (the screen that says "Samsung Galaxy S4 GT-i9505") but now it does not show anything. It turns on normally like it should, it makes the boot sound but does not show anything on the screen. If you have the lights turned off, you can see a flicker when it turns on and thats the only time the screen actually lights up. What do you think I should do? I still think it might be a software issue. Also I don't think I have warranty because I have flashed my phone a few times. Its still very upsetting that this has happened because honestly I haven't done anything to this phone.

Haha no I don't think so Well I'm still taking it back to Singapore but I will probably have to pay for the repair.
Does your screen not have cracked (from the inside ) ?

I don't think it does. Because before flashing stock rom, the splash screen would show and it had no cracks. So no actual damage, I still think it is a software issue but I don't know how to fix it :/ I still can't decide if I should take it to Samsung (which will take like a few months) or I can take it to a local repair shop and they can look at it which shouldn't take more than a week.

Repairing it doesn't take very long, taking it to the repair centre will take time. I bought my phone from Singapore and I have to take it there if I want to get it repaired. I took it to the Samsung repair centre in Bangladesh, they said they can't repair my model because they don't support it here :/

The same exact thing happened to me yesterday. Opened a text from a friend, tried turning on the screen and black screen. Thinking of sending it to samsung but do you have a solution yet? Was the problem diagnosed?
My Samsung galaxy s4 i9505 screen is dead--
I woke up this morning and my phone is still charging... But I cannot see my any data in the screen.. But my phone is still working.. I can receive phone call with my headset.. I cannot see anything in my screen.. It gone black.. Can anybody help me to fix this.. Or is this a firmware issue.. My phone has been rooted and installed official android 4.3 jellybean. Please help!!!
Just today I spend the same, except that the screen starts flashing, and at times the picture and the picture looked twice was very unstable, it restarts, and for the image of the i9505 without problem.
He ruled out a physical problem as it starts each. Device failure begins after displaying the Device Model
.
The touch and other features of the device, work perfectly. Try booting in recovery mode and I could not look very bad image.
In trying to backup my data with titanium to try to do a factory reset, began to regain normalcy. And right there my device works perfectly.
Bring 7 hours working normally my device. But I have fear of failing again. And now looking for information about possible solution. No warranty now.
What do you recommend? It's failure is becoming common. My device is doomed to die without remedy? Thank you very much for your answers in advance. Use translator apologies. Speak Spanish
hello guys, i got mine i9505 lte version 4 months ago. yesterday i pull it out of my pocket i tried to wake the device up but nothing .. just black screen just like the guys before me here. so today i opened the phone and pulled out and push it back the display connector... AND VOALA WORKS AGAIN! but after 5-10 minutes and everything is again black?! wtf i said!?! its not normal! my screen is working flawlessly colors touch response... everything! do i have to reconnect the display connector every time? i think its not normal. what must cause this bug/glitch/issue?!?!
i am rooted with cwm and cyanogenmod 11... i dont think its caused by the rom? what do you think guys? give me suggestion before i try to demolish the phuking fone))

Hello Guys, this issues is very common when you rooted the device and install Wanam Xposed.
You can try flash a stock Rom and stock Kernel with odin, try to swipe cache and dalvin using ADB.
Good Luck!
Hi,
After Xmas I made factory reset with TWRP and I made an upgrade to CM13.(6.0)
It was working fine.
When I was trying to make next daily update, after reboot, screen became black and nothing shown up.
I was trying a lot of things since that moment.
When I was going back from service point (I really want to sort it out) when they told me it is probably LCD broken (i have broken glass, but 1 year ago, so I do not believe it can be screen),
when I take phone out I spotted that keys are highlighted so I swiped and it locked out and shown screen! it was working perferctly fine,
so I decided that it is best moment to flash newest CM to solve issues, but after reboot screen was black again.
I can enter download mode so it is visible in Odin, but screen is black in every mode.
There is only quick flash on screen when turning on and also really short moment of Samsung Galaxy logo which becoming dark quite quickly.
I flashed stock rom(5.0), but nothing changed, despite of that I know phone is turning on somehow because I hear music on turning on...
Can someone help?
I really doubt that it can be hardware issue.
Can it be something with BL ? How can I solve it...?
