S4 only one horizontal line - Galaxy S 4 Q&A, Help & Troubleshooting

Yesterday, my screen turn off, or so i thought, there was a horizontal line on the top of the screen, and i saw it was the same color as the screen i was on. I immediately took off the battery and for a split second it worked before turning off. So i thought it was a low voltage problem, and let it charge overnight, and today it worked for 2 hours until it failed again. So.. if anyone knows how to repair this without replacing the entire screen, please let me know. i already checked if it was the conector, and it seems it isn't

If the screen itself is the problem then there is no way to fix it without replacing.

the thing is that when i take out the battery, it works before turning of

Hi,
It appears to me that it's some kind of problem with the screen as well, it doesn't seem to be changing the leds of the previous screen until it is out of power to keep them turned on. Unfortunately I'd guess the only solution is replacing screen.

You might try changing the software, but it might be hard to do if the screen doesn't display anything in recovery or download mode.

nope, it doesn't, i was hoping it was a software issue, but i noticed that it didn't display anything in recovery or download, so i opened the phone and checked if the display connector wasn't passed correctly or something, but to my surprise it was correctly connected, i went and disconnected and reconnected the pin, but it didn't helped at all

Screen "vibration" (flicking?)

Hi all,
as my signature says... yes, I sent my X1 to repair (cracks, as always). When I got it back, it seems to be perfect. Outside. Switched it on and it seemed ok.
As soon as I came back home, I noticed that the lower part of the screen "vibrates" (I can not define it in a better way... I suppose the right verb is "to flick"). At sunlight I did not noticed it, but at home and in the dark it is really really visible (and annoying, on a 600€ brand new phone).
Does someone ever had the same issue? or does someone know how to solve it (apart from sending it again to repair).
Thanks!
P.S.: searched the thread and foud nothing. Searched in google and just came up with a "refresh" problem, that does not apply to our X1... or can we change the refresh rate?!
I did once experience what I believe was the same issue, the flickering screen. The problem was still there after a soft reset and power cycle, but then after leaving the phone for a few minutes it turned back to normal.
Unfortunately I don't think I be of much help here as I don't recall doing anything special to get the screen back to normal.

Ok, so i just flashed back to froyo PD15IMG and the touchscreen works now, but the brightness is still not working, ive also noticed that every time i press the screen, it kinda fades a little... very weird... as u said before i think it may be a hardware problem..... any ideas of which part????
I believe that backlight is part of the display.

ok, so today i found more problems, rotate sensors are not working, compass is dead, and also the phone does not recognize any headset i plug in, i cant even listen to my music.... i remember that a week ago, i plugged my phone to a wall outlt with an iphone usb charger, do u think that has something to do with it???
thanks
Doubtful. Was it an Apple charger or a Brand X (off-brand)?
I seriously doubt that would cause a systematic failure of your hardware. If anything it would fry the usb/charging port, were there something seriously wrong with the charger.
Sounds like you've got a paperweight on your hands.

I have same problem with my phone.
The phone first had a problem when I left it in the sun for abt half an hour.
The brightness setting has no effect.
Auto rotate screen does not work, however touch screen works fine.
The phone hangs up now and then.
only the backlight does not work and i can easily use the phone inside a room
the compass does not work
tried factory resetting the phone no success
The charge light does not come on even when the phone is charging. however when i turn my phone off and charge it, the charge light comes on.
usually during startup or booting the device, the brightness is supposed to be full. however no brightness during boot up

Only fix i found so far for this problem was replacing the power flex plus the main flex of the phone.. that solved my problem...

good luck
it's done for...!
sorry bro but its good bye for your phone...!
I am having a similar issue with a friends phone. He had a cracked screen so i replaced that. 2 weeks later he brought it back to me and the brightness is stuck on the lowest level. Changing the level in options has no effect. I was just wondering is the backlight and the LCD screen one and the same? Should i bother changing the LCD or is there something else I should try repairing first. Everything else on the phone seems to function properly...its just a pain to see it!

[Q] S4 wont turn on

Well mine S4 turned of last night it freezed and it turned off. I'm on Broodroms Pre Final 4.4.4. After that it turned on and shows only the S4 splash screen and then it turns off again and it won't turn on. After i pulled out the battery and placed it back then it boots but then again it shows only the S4 splash screen and then it turns off again. I've read some things on the internet that it maybe can be a dead battery that is causing this problem. Or maybe it is an another problem maybe that you XDA members can help me it would be great :fingers-crossed:

If u can boot to recovery, flash your stock official rom. Should be fixed after that.
Or you can also flash your official rom in Odin.

Is your phone charged? The very basic question.
Put it on charging for a while try getting in the download mode then.
If still no succes..then there is a way too...

That happened to me once and reason was because the phone was not charging (even if USB has power supplied).
To solve this, I first removed it from the samsung charger and charged it using a laptop or computer for approximately 10 minutes.
That will get it charging

try booting into download mode if at all possible and try flashing a stock ROM via odin!!
hit Thanks if it helped!!
I've tried to connect it to my laptop but it won't charge unfortunately. I'm also not possible to get it in to download mode it shutdown after a few seconds. And it wil only turn on If I remove the battery and replace it the phone will vibrate, show the Galaxy S4 splash screen for a second or two, then it turns off again. Searching on the internet people say that it's a faulty battery so i could try that method and if that is not working i think it's something with the mainbord (i hope not)

Change the battery AND/OR
Try a USB JIG then. The final thing that can be done. Heard it works with i9500 too.
Buy yourself a USB JIG from ebay or something and try getting in the download mode. It costs less than INR200.

Sure.
Might be some moisture that is not letting the electricity pass properly too...
Clean the terminal of the battery and the connectors of the phone..see if this works?
Well something like this hapoened to my note 2 because of moisture in the charging jack..the charging jack was okay but the battery wentt kaputt.

I've made a video of the problem. Don't mind the screen it's broken for half a year so far and the phone was still functional. Last sunday this problem appeared and i don't know what to do so far...

Well i finally found the problem it was the power button that was jammed the whole time so removed the power button thing from the mid frame and the problem was solved so now i need to go to a phone repair shop and maybe they can solder a new power button switch on the mainbord thank you for your help and this thread can be closed now.

[Q] Is my Note 3 dead?

My screen is shattered, but the phone turns on and it vibrates when I turn it off and plug in the charger. Battery lights are normal for charging. Goes from orange to green.
However, when I try to turn the phone on it vibrates once then the blue light starts to blink continuously for a long time. After about 10 minutes the blue light is gone but the back and menu buttons are lit up and stay lit. I can't tell if it has actually booted or not.
If I try to ADB into the phone while it's in this state I can see it listed but it shows as unauthorized.
Does anyone know if I can I revive my Note 3 by replacing the LCD and digitizer? Is there anyway I can test it to see if everything is working besides the screen? I don't want to waste the money unless I know that is the only problem. I would really like to fix it if possible.
There is absolutely no water damage, just a really bad fall.
Try a hard reset with the 3 buttons. If it stays the same then you have a broken phone.

Can you please elaborate. How do I perform the hard reset when I can't see anything on the screen? I know for a fact that the screen is done for. I just need to know if the main board is still salvageable by replacing the LCD and digitizer.

You can't do a hard reset without a screen as it involves booting into recovery, then navigating using volume keys. If you have a custom recovery installed then it's even riskier to try it without the screen. So don't try it.
I'm assuming that the phone doesn't show up as an MTP device when you connect it to a PC?

Thank you for understanding my poor explanation. Yes, you are correct. Phone does not show up as MTP device when connected to my computer anymore. Does that mean I should assume the worst?
Unfortunately, yes. Just a shattered screen wouldn't cause 10 minute long boots every time (blue light only blinks when booting up, at Samsung logo) and the absence of MTP (even with lockscreen password/PIN/pattern the device shows up as MTP but it doesn't show the data unless it's unlocked first). It seems that the logic board of the handset is damaged in some capacity so just replacing the screen and digitizer won't do the trick.

That makes sense! Is there anything I can do to find out for sure if the phone is just in a coma?
I had set a pattern lock so I assume I can't access through adb somehow, right?

If your charging led and hard key lights blink, your phone is good. A display assembly replacement would help.
I received my Note 3 in this way (from a friend) and then I replaced the display and been using it for an year now

sm-t585 black screen

Hello, suddenly yesterday the screen of my tablet has gone black.
The tablet is on and working, because I can hear sounds when I press the keys but the screen is black.
Did anyone suffer the same problem?
I can try to repair it my self but I'd need to have some guess about what went bad
Thanks

I had the exact same issue. Fixed it by simply removing the back and disconnecting the battery and screen ribbon cables and putting them back on.
There are plenty of youtube vids showing you how to replace the battery. just follow one of those but stop after disconnecting the cables.
It's actually what I did and I have been able to recover the tablet.
Thank you very much!
