thnx for ur answer... mmm nope, it stays only at the lowest level...

oh God.... now the touchscreen is not working.... i dont know what happened, i cant even unlock my phone!! Help!! please.....

It sounds like hardware. If it were me I'd flash the froyo PD15IMG and see if anything magically starts working. If not, then I'd have my answer.

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!

GT-i9505 Blank Screen Problem

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 samsung centre here will send it to a repair centre. Here i will lose the phone for max. 2 weeks.

same problem
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, 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!

It may appear that your phone has suffered a hardware malfunction - You will either have to try and get it repaired or replaced.

Still go to a service center, seems like your screen is hardware damaged for whatever reason, never heard of this though.
Explain the situation and they might fix it for free, probably not.

[Q] LG G2 Screen Freeze (I'm starting to hate this phone)??

Hi guys

Something else that may be relevant is....
That it will always boot the LG logo so what ever is going wrong kicks in just after the LG logo
Even when the screen is completely dead i can get the lg logo up by holding the power button.

..

I've the same issue...
Hello Inked
I've exactly the same freezing on my D802 for more than one month now... And I have no idea what's happening too...
I brought it to a phone shop, he told me it's certainly a motherboard issue, he can repair it for 250€!... Way too expensive for me!
So, I decided to find a motherboard by myself and I don't find... I'm trying at this point to find the same phone with a broken screen to mix components.
It's a D802 32GB and it's quite rare in Europe unfortunatly.
So if someone has an idea how to fix this I'm at your disposal! And I can imagine it's the same for Inked.
I will try to post a video of the freezing problem tomorrow.

Go to http://forum.xda-developers.com/showpost.php?p=56259958&postcount=18. Read the guide to fix your phone

Are you sure it's the same issue?
Here is a video I've made of what's happening, the phone is not rooted (never been), flashed with rom stock EUROPE OPEN 20D, and hard reset:

I think touch screen is working because (it's not clear in the video) you can use the phone "normally" but the image stay frozen.

What do you guys think?

I've tried using your link but when i try and click the “1. click here to view picture” link i just get a 404 error.
Having said that, its not that the screen has dead spots, the screen freezes and just looks like a screen shot until you turn the screen off for a few second and then turn it back on.

But as atchoop says the screen is freezing as if you have taken a screenshot and doesn't start working again unless you turn the screen off for a few seconds.

A bit of an update......

I got the same effect as yours during few weeks then it comes back as my video shows because (I think...) I didn't use the phone for a while.
But I still don't know if it's mainboard or screen...

Samsung Galaxy S5 SM-G900H(exynos) No display, only sound & vibrations...Bricked ?

Samsung Galaxy S5 SM-G900H(exynos) No display, only sound & vibrations...Bricked ?
Hi, I have SM-G900H(exynos).
1. I was on AJ's S7 rom for SM-G900H(exynos) which was good.
2. But I wanted to change the rom but I wanted a lighter rom so I flashed lighter + v1 by yash92duster, after that my phone shows only blank display. I can
hear booting sound & feel vibration but no display.
3. I can go to recovery & download mode but can't see anything due to black/blank screen aka SCREEN OF DEATH. I have tried all Volume rockers + menu button methods for no good.
4. To solve the issue I flashed Official stock rom lollipop for India (INU) (downloaded from sammobile)....everything is good but blank/black
screen is causing me trouble.
5. I went to Samsung service center & they said your display is gone which will cost me Rs.11500/-($200). I don't want to pay 200$ for screen replacing because I think screen is not problem.
6. When the phone is switched off while charging, the notification red light blinks, during boot up the notification light is blue-green &
only multi-tasking button lightens up but the back button is no light.
** I don't have any backups. :crying:
WHAT TO DO NOW ? PLEASE HELP.

If flashing a stock ROM didn't help and the screen never turns on at any point there's a good chance the issue is hardware related. The led has nothing to do with the screen. Otherwise you wound sew an icon at charge. I've had my phone display not work while on a ROM. This is not that issue at all. I could still get into recovery. And the screen came on outside of the ROM.

Yes, there are reported cases of a loose connection behind the screen. But its not an easy fix, you can destroy the screen

Go to a not Samsung phone repair shop and tell them a cable at the back is loose and only works when you push on the screen. They can fix it. Or you can do it yourself but you need to really research it first. And remember its better to be overly cautious as opposed to eager.
