Galaxy S black screen

Hi all, I have a galaxy s and was going to install a new rom. I saved the rom to the sd card and pressed the power button to go into recovery mode, the screen went black as usual but never rebooted and the screen stayed black. I connect it to the pc and it tried to load some driver something to do with "test driver" but anyway the screen stays black and the phone does nothing. Any ideas how to fix this without sending back to Samsung. Thanks for any ideas. Wayne.

Does the phone show the samsung logo at the beggining or is it just dead black?

the same problem with me today blank screen, no vibration, no download/recovery mode, anything. The only sign of life is when I connect it to my PC, it detects a new device named SEC S5PC110 Test B/D , request a driver

You should send it back to Samsung. I'm thinking that its more than a software (ROM) problem when even download/recovery mode isn't working.

Same happened to me, try to get your phone back in restore mode with the three button trick. Amd reinstall the image again... it will work..

mine is just black does nothing except request a driver when i connect it to a pc. SEC S5PC110 TEST B/D. thats all it will do.

It is probably the deep sleep coma bug (I've had it ever since I flashed to 2.3.4).
Hold the power button down for 10 seconds and it should reboot the phone.

Remove the battery, leave the phone disconnected from the PC and get the phone in restore mode. Then when that succeedes, connect the phone to the PC.

I heard this problem in other forums when users flash a wrong rom or firmware. Only samsung can repair your device.

Try to access download mode: vole down button + home button + power button if you can access this let me know

Phone screen is black, but phone still "works".. Cannot get screen to come back on!

Phone screen is black, but phone still "works".. Cannot get screen to come back on!
I have no idea what happened, 5 minutes after being in my pocket I pulled it out and the screen was un-responsive.
The notification light is still on, power light, etc. The power button works, I can push and hold and reboot and the two bottom buttons on the phone light up. I was able to "swipe" my password and it vibrated and accepted it, I am getting vibrate notifications too. I just have a black screen and I can't figure out what to do!
I am rooted, but I haven't had any changes to the phone in a few weeks since I had rooted. I tried using http://forum.xda-developers.com/showthread.php?t=2786395 but I cannot figure out how to get the device to show up in the program to use.
I am at a loss on what to do...

No Samsung logo if you remove the battery for 30 seconds, replace it and power on normally?

Nope, no nothing. No logos, no screen flicker, no colors of any sort - just black. The LED goes blue as it boots up, etc, so I know it does power up.. and once it is done I can even swipe my password and it gives the feedback vibrate..
Just in case this was an issue with the root and whatnot I flashed the stock with Odin and I still am getting black screened.
I contacted VZW support last night, and the chat rep told me they would have to just replace the phone. I am guessing this may be a hardware issue.

Yea if there is no logo whatsoever when you first turn it on, it sounds like a hardware issue, not a ROM issue
I forget exactly which logo shows first (S5 I think) that isn't part of the ROM afaik, the Samsung animated logo is the ROM, so if you don't even get the one before the Samsung animation, doesn't sound good
Is it the G900F? If yes, the only thing I can think that might possibly work, is this

Don't use unless it's the G900F

I don't believe it's G9000F... and I am fairly certain now that it isn't a software issue since everything else 'loads', just not my damn screen.. lol.
Thanks for your help though

The reason I posted that link, is, if the bootloader has corrupted, it is possible you won't get any logo at all, and that debrick image basically tricks the phone into using the MicroSD card to boot into download mode from, where you can recover the main storage
It should tell you under the battery which model S5 it is
If the screen doesn't even light up, then it sounds more like hardware
See if this gives you access

It is connector issue.
Either connector is slight loose or if not then need to Change the connector.
My one has same problem.
Solved for less than 10$.

OK....Anything else I can try?

I own a Samsung Galaxy Grand Prime. Model is a SM-G530T. T-Mobile is the carrier. Running Lollipop version 5.1.1. Phone is not rooted. Phone has not been dropped.
During the first few months of ownership and during normal use, occasionally the phone's screen would suddenly go dark and totally unresponsive. My response was to try and go into "download" mode ( vol down, home, and power buttons at the same time) to enable me to run ODIN and reflash the device with the correct firmware. It should be noted that it was quite an adventure to get into download mode. Tried repeatedly to usually no avail (sometimes over a couple of days) to get the button combination to work. Eventually I could get it to enter download mode (sounds weird doesn't it) and I would reflash with success. Pretty sure I had USB debugging on. This sequence of events occurred 2 or 3 times.
Fast forward to the present: Encountered another dark screen episode, But his time I found it impossible to enter "download" or "recovery" mode. On occasion the phone would seem to boot up with chimes playing buy never anything displayed on the screen but with a faint back light present. My PC will recognize the phone as a Galaxy Grand Prime. Interesting, I would try to use ODIN anyway (after doing the download button sequence and hoping it was in download mode) and at times ODIN would go through its process and indicate "pass". Phone would appear to re-boot with vibration and chimes but again no display present except for a faint back light. Even tried Samsung's Smart Switch to flash the firmware to see what results could be had. Smart Switch recognized the Grand Prime and appeared to successfully flash the phone but again the phone seemed to reboot in its final act of the process but no display. Strange. It should be noted that I am not sure if I had USB debugging on before this last dark screen event. Tried using ADB and fastboot to see if I could do anything with the phone but those processes never recognized the phone. Bought a USB Jig to see if I could get into a visible download mode screen but that didn't work.
It appears that I might be screwed. Trying a JTAG procedure as a last resort doesn't seem cost effective at this point. Anyway any comment/suggestions would be appreciated.
Thanks in advance.

Just a follow up from my original post: Is there a chance that a defective LCD or screen digitizer could be the problem?

Is my digitizer dead? Galaxy S4

So I have an Galaxy S4.
Whenever I try to turn it one a couple of things can happen\
1. It goes past the boot screen and boots successful only for the screen to instantly go black. The blue led stays on.
2. It gets stuck on the Samsung Galaxy S4 screen
3. It displays a weird pattern
like this (https://dl2.pushbulletusercontent.com/xvul3t66cvpZwrXREYaVzfITYoxCFEGo/20170127_162841.jpg)

Does anybody know what is happening and how to fix this?

Flash new software and replace screen - 50£

I don't think a malfunctioning screen can prevent the phone from booting.
I assume it has something to do with your motherboard, in which case you either replace it or get a new phone.

Yep. The GPU is failing. I bet if he enters recovery mode he'll have a perfectly functioning screen. This is because recovery doesn't use the GPU.

M30s does not boot - stuck at very first screen

Hi all,
my Gylaxy M30s rebooted itself yestarday, and now is stuck at the very first screen (the one showing "SAMSUNG Galaxy M30s" in the center and "Powered by android" at the bottom).
Vol down + power results in a reboot attempt (screen goes black, vibration), but the phone is stopping at the same screen again.
I am not able to turn the phone off.
Switching from Vol down to Vol up immediately when screen goes black does not enter recovery mode.
Vol down + power while charging sometimes leads to the charging symbol being shown on the screen, but without the percentage in the middle.
Charging over night did not help.
The phone cannot be connected to a Win PC.
Any suggestions what I can try?
Thanks,
Alchemist

Try volume down+volume up and while pressing those buttons, plug your phone into your computer. Tell me the results of that.

Nothing happening...

I mean trying those combinations immediately after using power+ volume down to reboot.

What did you do with your phone? Died suddenly when normally using?

Yes, phone died during normal usage.
Ah, I see - a screen comes up warning me that downloading a custom OS might harm the phone.
Also, the PC makes this "USB connected" sound when I then press Vol up, but I do not see a new drive connected, I think.
I am slightly optimistic now?

Press volume up.Then install Samsung usb drivers(search on Google)

Ugh, just wanted to do this, but now the phone is completely dead. No response to any button or charging. Will hang it on the charger for a few hours, but my optimism is gone...

OK, now it works again. I am in the screen with the colourfull stuff and the phone waits for some download.
Driver is installed on PC. Is there anything supposed to happen - the phone is still not accessible via PC, or is it?

Install Odin (search in Google 'odin samsung' and download)
Download stock firmware(android os) at www.samfw.com , after downloading you will see files like AP-M505xxxxxxx.tar.
Select, from the stock ROM AP-M305xxxxx.tar for AP in odin CSC-M305xxxxx.tar for CSC, and so forth then click start .

OK. All data will be lost, right? Is there some way to access the internal storage to rescue some files before flashing the new firmware?

Sorry to tell you that you cannot have data restored bad news for you sorry

Sorry. If you only see one file(make sure it is .tar or .tar.md5 file) after you extracted the .zip firmware, install it to the AP slot.

Any chance I could fix this issue with tools like dr.fone, UltFOne, ReiBoot?
I do not have any experiences with these - no idea if the just want to make money with desparate customers? ...

These could possibly brick your phones even more ( anyways flashing with Odin could also brick your phone). However, it in some cases can fix your device.
If you HAVE to have your data back and you don't mind paying, visit a service center and tell them: 'Hey my phone died and i HAVE to have the data back '.(I know, your warranty is expired probably, but they might still do the things for you with paying.)(if those stores closed during lockdown then I don't know any way to fix it.)

OK, another thing I have observed: The screen goes black after about 30 sec to 5 min when not charged - the shorter it was charged, the quicker the screen goes black. Buttons do nothing when screen is black. When reattached to charger, phone tries to boot and is then stuck at said screen - no button pressing needed for the phone to try to start. The longer the phone has been without charger, the longer it takes until the phone tries to boot.
Maybe it's just the battery that is dead - or would the phone with a dead battery boot normally when attached to charger?

If that is the case, open up your phone, put in a replacement battery, and try to boot up(yes, you need to. it will be a frustrating process.). Your phone could be having a faulty battery and nothing else, to cause this issue.

Im having the same problem mentioned above. The samsung service centre says to replace the motherboard which costs almost half the price of the actual phone..

Truth to be told: The guy in the repair shop opened the phone and wanted to change the battery - when he saw that water must have come into the phone, corroding the motherboard. So yeah, all data lost, but... no backup, no mercy. I now have set up a NAS for all computers and devices in our family... ;-)

If it really is a hardware problem then the quality must have been really bad.
