screen wont turn on...

i dropped my phone and since then the screen refuses to turn on. it seems like everything is working fine except the screen. calls are coming through and im able to answer the call as long as i swipe at the right spot. is this something that can be fixed instead of swapping out the phone? if this cant be fixed and i have to get a new unit, can the sprint technicians be able to somehow transfer everything over to the new phone? btw, my phone is rooted with cwm installed and nandroid backed up to internal storage since i have no sd card installed.

If you can connect via USB you can grab the data from internal storage possibly, but it sounds like, at best, your display has a hardware issue ( strange that the touch works but the display doesn't)
But I see a trip to the phone store in your future.
If you can, I'd recommend booting to the boot loader (pwr-voldown) and using Odin to flash a stock from first so you can at least have the chance of getting a warranty replacement. ("Not sure what happennes, the screen just doesn't work anymore...")
Good luck.

Sounds like something with the connection between the LCD and the motherboard. You could get lucky and only have to reconnect the LCD's ribbon connection, however, if the LCD is cracked in any way, it would have to be a replacement, that is, if they allow replacements on cracked LCDs. Every ASC location is different. The only way to transfer anything would be to connect it to a PC, like he said in the above post, and hope it connects as USB storage by default. Copy everything to the desktop and then drag-and-drop onto the new phone's storage. But dude, get an SD card. It really makes EVERYTHING so much easier when transferring to a new phone.

The LED back light system and the touchscreen are independent of each other. Sounds to me like the connection to the back lights and the power got disconnected.

that is exactly what it seems like. can i take it into a sprint store and have it repaired or do i need to send it off?

As long as there is no physical damage then I would say its repairable. If you have ever seen a smartphone dissembled you should go check it out on you tube. Alot of the connectors are very small and easily popped out.

[Q] Screen's gone fuzzy and weird - Solved

My Captivate Glide's screen does this whenever I turn it on:
I didn't drop it or get it wet, it just started doing this randomly.
I live in the UK and ordered the phone unlocked over eBay so I can't take it into an AT&T store, sadly.
Do you guys know if there's anything I could do myself or anything someone more experienced in repairing mobile phones could do to fix the screen?
This is bearing in mind that not many people over here have seen one of these phones though.
Any help would be massively appreciated. Thanks guys.

you was using still GB right? just flash ics via odin, with one click or with a tar file
This is UCLH2 without one click
http://androidromupdate.com/2012/09/...ota-stock-rom/
And here is the latest version with bug fixes (like keyboard light)
http://androidromupdate.com/2012/11/...ptivate-glide/
and there is for one click
http://www.androidauthority.com/captivate-glide-sgh-i927-att-android-4-0-4-ics-uclg9-leak-110365/
i think that only one click wipe your internal storage. but is the bes (in my opinion). try it, dont have anything to lose

No, I already updated it to ICS. Should I reinstall it? Will that fix the screen? How will I manage to do it with the screen all messed up?

if you can put in download mode, then you can. Its weird because i only see that problem with GB. Put in download mode and then reinstall

I just tried putting it into download mode but I get the exact same thing.

Thats weird, the problem is weird because it never happen to me in download mode, maybe you can try it without battery, or let the phone without battery a couple of hours, etc.
Dont Know what you cand o, because if you cant enter in download mode, you will be no able to flash ICS

Hrm... that purple splotch in the bottom left of the screen doesn't look so good... Almost appears as if it had been dropped on that corner at some point in the phone's history. I am tempted to say that is a hardware issue, though. Reminds me of when the flex cable for my laptop's display started shorting out many years ago. Might be repairable, but, might be a costly repair depending on what all needs to be replaced. I can't imagine replacing the software on it will do much, though, sorry to say. You could give it a shot, you can verify if your phone made it into download mode without the display by loading up odin and seeing if it detects under that, and then running the one click install (or any other since you'd have odin running anyway) but I wouldn't expect much.

If you're not getting the Samsung/Rogers logo screen, you're done. Either the screen is physically damaged, or the bootloader is corrupt. There's no saving that one, sadly.

yes, try what Artemis-kun say. put in download mode and connect, and see if odin detected. Or maybe just turn on the phone and wait a little, then try to call to your phone, if the phone ring or appears to be on, then is a hardware problem.
But try what Artemis-kun, maybe you have luck
PD: now i see better the image and it seems little different from what it happens to me. if you turn on, inmediatly happen that? or screen banish slowly?

AW: [Q] Screen's gone fuzzy and weird - need help please
There should be a cable, connecting the hardware to the display. Maybe it loosened, you should check out the video of a guy tearing his glide apart, hopefully youll find something to repair there.

Hey guys, you'll be glad to hear I finally fixed my Glide by installing a new screen assembly from Repairs Universe.

[Q] Galaxy Note 2 dead.

Hi all,
I have a galaxy note 2, bought in November 2012, I rooted it a few months ago.
Yesterday it was fine, battery was fully charged and it was in my pocket.
It was not doing anything out of the ordinary but when I went to check the time I noticed it was off and I couldn't get it to switch back on at all I tried removing the battery, putting it on charge and still nothing. I tried recovery mode too - nothing.
The only thing that happens when i try switch it on is the little red light from the proximity sensor flashes for a split second.
Has anyone heard of this before?? I've searched and cant seem to find anything like this.
Any help would be greatly appreciated.

try to flash Stock firmware via Odin....

Unfortunately this is the main symptom of Sudden Death Syndrome (SDS). There is no known way to fix it by yourself.
Contact samsung service center ASAP.
Can you answer these questions.
Which firmware was installed on your device?
Have you updated your device to the latest update?
Till you updated it, have you done a factory reset with the old firmware?

I`am sorry but you have to bury your motherboard. Take it to a repair center to get it fixed. Bad luck bro

Exactly what was happening to me. Had the Notification LED blinking, wanted to check, couldn't manage to turn on the screen. Tried rebooting, but can't even see the boot-logo. Battery pulled - nothing. USB port not working when connecting to a PC.
I had MIUI on it with an increased counter, since here in Switzerland it isn't a big deal when you mod your device.
I hope they will ignore the fact of the increased binary flash counter...

[Q] Stuck in boot load after screen replacement

So, my screen cracked by itself but I didnt get it fixed on the warranty.
Anyway, I bought a new screen from ebay, seemed allright.
Got it yesterday. Took off the old cracked screen, maybe a bit hard cause now its super broken.
When I put the new one in the phone doesnt boot. Just shows the Sony logo then reboots in infinity.
I did PC Companion repair which didnt say anything special just that it got the work done. Still the same problem.
Did the Sony Emma program which should flash the phone the offical way, right? No problem according to the program but when I try to start the phone the same problem.
Tried flashtool and flashed the phone with official..hmm ftf file. Still the same problem.
If I connect the old, very broken, screen the screen lights up all the time on the back side of the screen (the screen doesnt show anything on front side since its really broken) but dont know really if it kind of works.
So, did I screw up the phone when I took the screen off and broke something or could a faulty screen (the new one) actually be what causes the boot loop? That seems weird to me but i gotta ask. If the phone was really dead Emma or flashtool would say so right?
Any thoughts?
Thanks

Some new information. With the old broken screen I can connect the phone to the computer and the phone pops up in explorer. Which it doesnt with the new screen. Bloody what,

Is the "new" display unit original from Sony or a chinese replicat?
If not original, i think it is a hardware problem (chinese crap...)

Yes, its a chinese copy. So that is probably my problem.
But since it will take months to get a new one any other ideas would be very nice.
Its just weird to me how the screen causes reboots, but I guess thats it.

Hi, did you manage to get it working with an original screen?
I have the identical problem.

Same problem
I have the same problem has anyone resolved the issue
Thanks in advance

[Unsolved] Screen issues

Video of the issue: https://www.youtube.com/watch?v=XzIx9SHj6MQ&feature=youtu.be
According to my sister it has always had the screen "artifacts"as shown in the video where certain pixels are the wrong colours (which apparently never set off any alarm bells in her head... ). But apparently the screen and device stopped responding correctly a while back which i have been able to find out can be fixed by taking the back off the device. I can not use the recovery on the device since it just displays multicolored static on the screen, same thing happens when the device is plugged in to charge while powered off. I told her to get all important data off the device and factory reset it so the device is all at factory defaults to rule out software issues. After that didn't work i took the back off the device to check to see if the screen was connected correctly and to see if there were any obvious issues such as the cable being visibly damaged or disconnected etc.
Image of the issue when charging: http://i.imgur.com/Kat1RoC.jpg
So everything is stock on the device. It has never ran anything but official updates directly from Google.
The device is out of warranty and considering the cracks on the corners of the case i doubt Google/Asus would be happy to fix the device out of warranty without it getting expensive. It would be nice to fix it if it is possible or financially viable.
Any ideas and suggestions appreciated!

Have you tried a factory reset? If not, have you tried reflashing a stock rom, wiping everything?

It has been factory reset. I have not flashed a new ROM to it.
I have actually fixed that issue by putting some padding in to prevent the cable from flexing so much inside the case. So the device now functions as an e-reader and web browser. But it still cannot play video or cope with scrolling through images and so on due to the tearing. It gets worse the more that is updated on the screen. This may still be a cable issue.
I would flash a new kernel and ROM to the device but download mode doesn't work since no computer can recognize the device. In download mode and recovery the screen shows the static as shown in the image meaning i cant really use it easily. Since it is still running stock recovery i cant just flash a zip file, since download mode doesn't work it may be difficult to do the above.
But i only have experience with my own Galaxy S2 which runs custom everything. So my experience is with Odin and CWM, so i am not familiar with download mode for other manufacturers.

The second image, I know this. I was fiddling with the ribbon cables one day and I also got that distorted screen.
If it appears when charging, sounds like...the cable is not grounded or something and the signal(to/from the ribbon cable) is being distorted. But that is just a guess, it could be anything.

Its not exclusive to charging though therefore i dont think it is power related. It happens every single time the system displays something on screen outside of Android. So the charging screen, recovery and download mode are all displayed as that.

Have you tried fiddling with said cable when you get the distorted image, in an attempt to perhaps fix it? it's odd that it appears with system messages. This sounds more and more like a true hardware issue(a defective unit) than software or a "simple" ribbon cable problem.

Not while it displays that image. But i have unplugged it and plugged it back in and nothing has helped.
My theory at the moment is that the cable is damaged meaning when the device tries to completely update the screen data goes missing and it struggles. Since videos dont work at all while the android flappy bird clone works flawlessly since it doesn't need to send as much data to update the screen due to the solid background colours and so on. But there are still holes in that theory, for example the issues become many many times worse when the device is in landscape mode.
So as far as i can tell it could be anything from heavily corrupted software to broken vram and anything in between including broken cable (since fiddling with that has fixed a different issue, perhaps its related) to the displays RAM for storing the previous screen update being broken. I can't tell.

Defective VRAM is also a possibility.
But I am not aware of any tool(for Android) that would allow for direct memory scanning of the VRAM. If you end up deciding the tablet is a goner, and want to buy a new one. I'd advise against another N7, it's already old, and the bugs are not worth the hassle.

Yeah, im not aware of any either. I have also been through all the relevant debugging tools. Telling the screen to flash on update actually made the device function much better (where it flashes pink on each update) it stopped the issues from being serious. But lets face it, no one is going to want to use a device with that debugging option left enabled.
