With the phone off .. Press 1 (on the keyboard) and power. If so, maybe try to odin back to EC05 stock

good luck

If on boot after pulling battery it is still black and download mode shows nothing, and you have tried Odin (it works but you see nothing still) I am afraid you need to head to the Sprint store.

try to odin to ec05 stock ... leave your phone again for a while and see when you get your screen back if you can get to download mode and odin that stock rom ... this will allow you to see if it is something up with a rom you're running.
if it does it then, you'll be at stock so when you go to the sprint store; it won't be an issue.

I agree Odin back to stock is your best option and if that dosn't work you probaly stuck with a black screen!

Yes, if you got it to come on once by leaving it you should be able to do it again and Odin before making any calls.

I had no choice but to take it to the sprint store

Hey, I know this is an old post but I have an old Epic I'd like to see if I can trade into for credit towards a Galaxy S III but I'm having the exact same problem as described here:
Softkeys light up, screen hepatic feedback "buzz" can be felt, can swipe to unlock and answer a call based on blind-memory of what to swipe but other than that, the screen is completely black. Not black as in lit up but devoid of any other color except black, but gone dark.
If it weren't for the softkeys being lit, I would assume the screen were either broken or disconnected from the motherboard somehow. There are no cracks in the screen. Phone has seen better days for sure but the screen is intact and all functions were working perfectly before it simply...blipped off in front of my eyes.
I've tried doing as you did: charging it for 3+ hours and seeing if that worked at least temporarily. No go.
Assuming our two phones were experiencing exactly the same issue, can you tell me when you had it repaired, if the issue was a hardware or software issue? If hardware, did they have to replace the screen? or was it merely not connected properly somewhere?
If it was a software issue, how did they repair it? I'm assuming I can, in fact, get the phone into download mode, but without a visible screen, I can't boot off of a zip file or see if any of my actions are successful. Can't be sure I cleared the caches properly before I proceed, etc.
Phone was last running toadlife's CleanGB prior to the FC09 update and I'm pretty sure, prior to EL30 (I can't remember but I'm pretty sure it was).
Again, I know this is old but any feedback would be appreciated.

Hm, so you're saying download mode or recovery mode open up but with a black screen? But it still reads touches? My guess is it's hardware, a loose connection to the screen.

Yeeeeah, good luck towards funding your S3 purchase.

I'm having this issue have my phone was dropped yesterday, so I'm quite sure it's a hardware issue.
I have two questions: can somebody be so kind as to give me the button sequence for how to make a nandroid of my phone? I have CWM 5.0.2.7 without the 'one confirm' option. That would be awesome. Also, is anyone familiar with taking the phone apart and perhaps how to fix this issue?

Thanks tazfanatic. I tried the backup procedure and it didn't seem to work, and I think I actually have CWM 5.5. Is the procedure any different?

Indeed. I'm running CM9 beta 2, and I'm pretty sure it came with 5.5. However Taz, I believe if you boot into recovery from ROM Manger or the power menu, it still takes you into your previous recovery version (such as 5.0.2.7). Or vice versa. I don't remember. To my knowledge, this is has something to with the switch to MTD, and the devs just have reroute that command.
But regardless, I'm not getting a new backup on my SD card, so I'm pretty sure I'm on 5.5. Kenny, do you know if there's a different button sequence for 5.5?

5.5 is the same. I would remove the battery to make sure it is powered off. Put the battery back in, hold camera, volume down and power in that order (making sure power is last) for 5 seconds. wait 20 seconds to make sure it booted into CWM 5.5. Then volume down 4 times then camera twice. Depending on how many apps you got I would wait 30 minutes before pulling the sd card to check in clockworkmod\backup directory for a new file with current date code.

Unresponsive screen after wake?

Has anyone else had an issue where the lock screen is unresponsive after you turn it back on? Here's the scenario:
1. Using tablet.
2. Let the screen time out normally or press the power button to turn off the screen.
3. Wake the tablet either with power or home buttons.
4. Screen is completely non responsive. Doesn't register any of my touches on the screen. Have to power off and on the screen multiple times before it allows me to unlock the screen. Orientation doesn't seem to matter.
I have a brand new WiFi only edition, model P600. I immediately did the three small OTA updates Samsung pushed to me as soon as I first turned the tablet on, but I'm pretty sure it was happening before, as well.
Anyone else? Haven't seen mention of this issue here so far.

Never had this problem on my Note 10.1
Yours could be a just a software issue - Try doing a factory reset and see if its anyway better if not then go back and get it exchanged.
P.S I have had this issue just recently on my S3 and this was after doing a recent update (which then got cancelled due to it causing lag and errors on peoples S3's) so I just need to find the time to factory reset it and all should be good (in theory)

Yeah, I was afraid of that. No joy on the factory reset. I'm rooted and so the Knox stuff is tripped and shows "modified." Hope that doesn't come back to bite me. (Btw, issue was apparent from first boot - before I rooted.) I'm about to go find the factory firmware and ODIN it back on here so at least there's no trace of SuperSU and all the bloatware is back. I think my parents got the Note from Amazon, so hopefully they won't look too closely anyway.
Thanks for the reply.

FWIW, I've tried factory reset, flashing firmware straight from Kies (UEUBMK1), turning off Smart Stay, Palm motion, Reading mode, and I'm the only user registered on the device. No joy on anything. Just going to have to send it back to Amazon for replacement.

Have you tried disabling Daynote?
I've found that when I freeze Daynote the magnetic sensor from eg the book cover case don't work anymore.
My train of thought is that maybe your magnet sensor is defective and Daynote ends up in an endless loop?

[Q] Screen wont turn on

I have the new Galaxy Note 2014 edition tablet, as does my son. My son came home today with his tablet and told me the screen no longer turns on. He said he was playing a game with a friend when the screen flickered and then went dark. Nothing seems to bring it back online.
Tried to press the power button and volume up button for a forced reboot. Most times does not but it did reboot once and stayed black.
Also tried pressing the power button down while pressing a finger on the screen, apparently a solution to sleep of death or something. I can't tell if that does anything - if anything it seems to turn it off or something because it has become unresponsive after doing that.
Any thoughts on what to do next?

I seem to be able to get it into two states right now, but neither is like it was - powered on and "working" but no screen. If I hold the power button for a while it seems ot go into a deep state of sleep or off, but I do not quite think it is off. If I hold it again for 30 seconds nothing happens at all. If I hold it again for 4 seconds, the back and menu soft keys will light up again. And then I can get them to light by hitting the home button or a quick touch of the power button.
Press and hold power in either state while holding volume up no longer seems to take me to a reboot - I no longer hear the power up music.
No idea what state it really is in or how to get it out of this.

ok - I think when it is able to light the buttons - it actually is still on. I just heard the vibration notification of an incoming alert (email, twitter or something).

Use the function to chat with the amazon support.
just google "Amazon Support". You will find the option on the right side on the amazon page
They will know what to do and from my experience amazon will offer you that you can send your tablet either to amazon or directly to samsung and they wil pay the shipping costs good luck !

If you are within your refund stage then get it exchanged for a brand new device if not then yeah you will be covered under warrenty.

Its a problem with your tablet. I know of a few other people in other threads who have also experienced this. My experience was different though because mine didn't turn on out of the box. I think there's a problem with Samsung's display connector. Your best bet is to just get it replaced at this point.

Yeah - it looks like that. I was hoping for a service option because my son has a lot of homework on it that would be nice to retrieve and of course he is bummed that he might lose all his game stats. I tried ot hook the device up to the pc to see if I could copy some files but although the device shows, its internal drives do not show up.
I really do not know what state the device is in right now. The soft buttons light up and if i pull the smart pen out it vibrates as it acknowledges it has been taken out, and I can hear the occasional vibration notification as an email, twitter update, or some other notification comes in. So - it "seems" like it is on. But I can not get it to do a forced boot and a few other things seem not quite right.
Anyway - Thanks for the help everyone!

That's strange that you can't see the drives when connected to the computer. If you look really closely though it could just be the backlight not turning on when the actual lcd is turning on. If you really need to see whats on the screen and try to find a way to send the files to yourself or upload them somewhere you can try taking a screenshot while the tablet is connected to the computer and check the screenshots folder to see what is on the screen at a certain time. I know it could take a while, but if what's on the tablet is really important it could work. Best of luck.

I tried to see if there was anything vaguely showing but the screen is totally black as far as I can see. I have a service ticket open with Samsung and will send it back for repairs. I would prefer repair over replacement as I would hate to lose all the stuff installed. I generally trust repairs as my philosophy is that they tend to pay better attention on the repair than the assembly line.
Thanks for all the help everyone!

You should definitely try getting it repaired or see if it's possible to copy the data to an external storage prior to getting a new one.
As a general rule I always have Google Drive take automatic backups and store what I can on my external SD to prevent any loss of important work.

Don't you have to unlock the device for the drives to show up on the PC? It's probably waiting for the lock screen to be cleared.

This is what I am thinking - that it is sitting at the lock screen. I tried to see if I could unlock it by touching the screen in the right places but I guess when the screen is dark its not just dark but not functional. I figured as much but thought I would try anyway.

Well - its going back this morning for either repair or replacement. I would prefer repair to save the apps and data and work. Nothing irreplaceable but its a royal pain to reset all this up and my son had significant game experience on the device that might be nice to save.
Either way - it will just be nice to get it working.

Just wanted to follow up with the results. Got notification from Samsung yesterday that they repaired my device and it is on its way back. They replaced the LCD screen and the battery. All free and in warranty and coming back 2 day air.
Not sure why they replaced the battery. I wonder if the battery takes a beating because of 1 game that we play - Bloons TD5. It tends to drain the battery from full to empty in about 30 - 45 minutes. Any other game or function we do the battery last many hours. I wonder if that damages the battery long term?

HOX Touch Working, but doesnt Show up Light

Hey mates,
My HOX went down in terms of charging yesterday and I charged it for a while(It didn't easily get charged at first)
After working for a couple of hours, my screen goes off, and doesn't come back.
The Capacitive Buttons are working, and random apps can be opened by touching on the screen randomly(like torch apps)
Is is a software problem or a hardware one?
Is it something related to the voltage that handles the Screen?
Any help would be grateful!

Navigation button LED lights stopped working?

I'm not sure why my LED lights for the navigation button stopped working completely. No it's not the option in the Display setting, both options have no effect.
I purchased a new charging board (it includes the buttons) thinking the board was somehow damaged and replaced it as well, still doesn't turn on.
The buttons still work, I just kind of miss the light... Does anyone know what other hardware possibly could cause this? Or have a schematic for this phone?

Is your phone bone stock or have you unlocked it and run custom software? Have you tried backing up all the data stored on the device, and then doing a full device format and RUU?
Did you void the warranty when you replaced the charging board?

Oh I just thought of something. You have battery saver and extreme battery saver disabled right? And you're not using any third party power saving effects?
Sent from my HTC 10 using Tapatalk

Warranty is def void, not that it was in warranty anyway anymore. This phone is way old. I daily a S8 now, the 10 is my business phone now. I'm trying to avoid a RUU but the phone is basically rooted with no custom rom, all I run is adaway. Never had issues in the past with it.

Same problem
I have the same exact problem and bone stock s-off and rooted Plus I just I did RUU. What else is there to try?

Issue still persists, I don't even care to mess around with it anymore. Phone isn't my daily driver so I'm just going to live with it for now, until someone figures out what causes it. If you do somehow figure out what the problem is, please let us know.

Same, never figured it out. Changed the buttons out too with new and it didn't fix it. Sold the phone like-so a long time ago. Good luck!

Have the same issue as you, after battery change. Did you resolve it in the end?

You can't fix the light. This is a problem for all HTC's 10. I bought 8 new pair of buttons from different seller. Light doesn't work at all on ALL 8.
