LCD wont work still after replacement - T-Mobile Samsung Galaxy S II SGH-T989

Hello everyone, About 6 months ago I cracked my screen on my phone. I used it for about 3 months after that until the LCD went black. The phone still booted and I can hear notifications coming through, so I figured it was a hardware problem with the LCD. Today I replaced the LCD and it is still just a black screen, and I can hear it booting just fine. I would like to try to restore my phone to factory setting to see if that will help. How can I do so without using the LCD? Does anyone know what other problems this could be? I appreciate the help
It has a custom rom install, I am trying to remember what it is so I can post it on here. I think because its custom I will not be able to use KIES

If you can't even see a boot logo when you first turn it on, restoring factory rom won't help sadly. You have deeper hardware issues then you initially thought ( mainboard possibly or a bad new lcd ).

U can try putting the phone into dl mode by turning it off and holding vol+vol- while plugging it into PC, give it a second and press vol+ then open odin amd see if it connected, if it did flash stock rom with Odin, now just so u know this is a long shot as I doubt it'll help but worth a shot always

HTC One X Screen won't turn on, touchscreen still work???

I have been using the HOX for over 2 months now but this morning my phone display suddenly doesn't turn on even the backlight key still on and touchscreen still work ( when I sweep my finger up the unlock sound still play, and I can even adjust the volume of the phone, etc... ) I have no ideas if this is a software or hardware problem and how to solve it, I'm still on Stock Rom, Stock Kernel,... Please help me
try to reboot pressing power button for 10 seconds, if it'll not work, it can be hardware problem, as i understood you haven't unlocked it, so you can send it to htc and they will repair it, or if you can, you can change it by yourself,
have you tried starting in bootloader and factory resetting?

Yeah I tried to reset the phone, ai first it worked. But when I turn the screen off and doesn't use it for a few minutes, the problem is back again, It's really odd, I have heard about lots of HOX Screen problem but I haven't seen this one before
So the screen works in bootloader?

Sometimes it does, sometimes it doesn't. Really weird, it feels like the phone has woke up but the display still "think" that it still in standby mode
Hardware fault for sure.
Same Problem
Hey, ive been using my international HTC One X for about two months too now and there have been no problems. ever since the update to 4.0.3 ive been facing exactly the same problem. The screen does not turn on a lot of the time but the touch is active. Have you found any solution to it?
It would be great if you could help me out.
Thanks

I have the same problem now. Using it completely stock, the screen doesn't turn on. Well.... Except for the times I visit the Vodafone shop to get it fixed....
Their first reaction was a defect in the screen, so they ordered a new one. I brought it yesterday again and it is now in for repair.
I don't know if this will solve the problem. How did they fix yours?

I get my HOX fixed last week and I worked normally again. But after 2-3 days, the problem is back again. I contact HTC and they said they even replaced my MOTHERBOARD and Screen. Wtf is happening???

hey guys
I had this problem a month ago, i know its frustrating.
anyway the only solution is factory rest from boot loader and flash RUU (worked for me)
the first time i had it, i did a factory reset, all my pics music were gone, phone went back to normal( stock, locked)
after a day the problem appeared again, second rest.
flashed RUU and the problem is gone. thanks god i have been using my HOX about a month science that problem and every thing is working great.
im sure its a software issue and I recommend every one to back up their files(pics,music)
just flash RUU and good luck
Lol, exactly the issue I had recently had with mine. Sent it backto htc, let's see what they would do about it.

My colleque has the same issue with his One X.
It started with suddenly everything on his screen looking "zoomed in", so everything double size, looking ugly as a mofo, and not usable. After locking the sceen and unlocking again, it was fine.
Monday suddenly also screen didn't want to turn on anymore. Did the hard reboot for him, and it worked again... Untill he locked his screen and wanted to unlock, same issue.
Also, that time when doing the hard reboot, screen didn't turn on at all. Did another one, and worked again.
He's now sent it in for repair, this definately sounds like ahrdware issue, even full reset through bootloader didn't help.

Yup, exactly the same problem I'm having, I sent it to HTC, they said they fixed it by replacing the motherboard, but now it is happening again, I will have to send to HTC again.
This just happened to my phone... Has anyone else solved it? Is reset and flashing RUU the solution?

I have the same problem right now.
It started last week when I was using Flipboard and suddenly everything started zooming in and stuff (same as mhulsegge above). It was resolved by locking my screen and unlocking it.
Last night, i've been getting the black screen when I try to unlock my phone. The touchscreen still works but the screen is just blank. It turns on if I keep locking and unlocking, but it's getting annoying.
My phone is an international One X (duh) bought in Hong Kong and I'm currently living in Canada so it would not be possible to send it back for repairs. Plus my phone is rooted and I am currently using the latest MIUI ROM (2.9.21). I have been using an app called "Sleep" which tracks your sleeping patterns. It requires you to place your screen face down on your bed when you sleep and the accelerometer will track your sleeping patterns and wake you up at the most optimal time. I assume that for the accelerometer to work the screen has to be on, so I am wondering if this can be a screen malfunction (overheat or overuse) problem since the screen has been on for so long (every night when i sleep for around a month).
Since sending it back is out of the question for me because of where I am living right now and I have voided my warranty, I am downloading other ROMs as we speak and seeing if it is a problem with my ROM. I will keep you guys posted.
-edit- I have tried factory reset and reinstalling my ROM (with a full wipe). Still doesn't work.
It´s probably not your rom since I use CM10 hand have the same problem and others have even been running stock and had this problem. The only one who seems to have solved this (at least in this thread) flashed RUU, so guess I´ll go try that now...
Would be great to hear if anyone else has solved it, and how!
edit: This has to be a hardware problem, if I push on the screen it starts working! Its like something is loose, and when i press on the screen it gets connected again.

Good tip, but I tried a gentle two-fingered push (zoom pinch) and the backlight turned itself on with very little pressure, certainly not enough to flex the screen. I believe that it is a state issue related to zoom, but will try again and report if the issue returns.
Screen black after replacement lcd display unit
Hi,
My HOX touchscreen was broken, the touch and everything was still working. I ordered a replacement lcd display Unit and replaced the complete display and touch. After replacement the screen is completely black but the phone still works. The touch buttons on the bottom still work and i can use the volume buttons. I replaced the lcd display unit very carefully and i am sure nothing is broken etc. So the touch is working but the screen is black. I tried 2 display units and both show me a black screen.
Does anyone know how to solve this problem? Did i forget to do something during the replacement?
Please, i need some help with this issue.
OneX has too much issue with Screen . WTF with HTC?

Power Button/Restarting issue

4.0.4
CM9 alpha 6
Yesterday my phone just started rebooting randomly in a loop, it would get to the launcher and boot up completely but would just automatically reboot, as soon as i would the put the battery in the phone would turn on without even touching the power button, i was able to get into recovery and wipe/reflash my rom and that seemed to fix it but then my power button stopped working and the rebooting issue returned, i wiped and reflashed etc and did this twice and now i'm stable but i'm afraid the issue will return.
What is the issue?
What/how should i update to a new rom?

Only way I could see you trouble shooting that is by taking it apart. If you do be careful with the screen

Keep in mind that this is a hardware issue and changing roms is unlikely to fix it. Unfortunately, if you can't fix it yourself you're going to have to shell out $35 on a repair or just have to deal with it.
who does the repairs? regular sprint stores?

[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.

Cant be because it does not restart in recovery mode or download mode. I actually did a full wipe system and it fixed the issue. But now i realize when i start downloading my banking app, pandora, and other apps it starts crashing again. I dont know what to do.

I took it to a repair shop, where I was told to send it to Samsung to do a heavy-duty root. The power button does need to be replaced because there is no spring when you push down on it. I have no idea if there's a root glitch. Has anyone sent their phone to Samsung? What happened? Are there alternatives?
Thank you!

It was amazing, I had the same problem but all i did was open up the back up undoing all the tiny screws and then took a can on compressed air and sprayed out the power button and its been working for more than a month now with the problem completely gone! try that first before sending to sammy.
Ok I am in the same boat. My device does not boot up, it will get to Samsung logo and restart half the time and the other half just vibrates every 2 seconds. I removed the battery while plugged in and it still vibrates. I took it apart and blew the power button with compressed air and nothing. Here is the funny thing if I bang the hell out of it, it almost boots up. Is there something that I can do less than sending it to Sammy ? If not I will sell it on craigslist for parts.

Same thing here. Only way to get it to power on is by hitting it, the harder the better it seems. After it turns on, touching the power button will make it go in to the restart loop 90% of the time. This sucks!
For me this started after I dropped my phone...with the case on and on carpet. I have also opened it up and sprayed with compressed air to no avail.

Hi Folks,
I had the same problem, the problem started when I dropped my fone on carpeted floor, here are symptoms
Fone restarts on its own, start the boot, inbetween the boot starts again, then, keeps vibrating every two seconds, you have to pull the battery out to stop it,
As soon as you put the battery back in, it restarts, again getting stuck, and then vibrating every two secods,
Here is what i did
- Cursed Samsung for making a sh***y phone - Didnt work
- Smacked my phone with whatever I could fine - Didnt work
- Opened all the screws up, took apart phone, pulled out the power button module (pcb), noticed power button was loose,put some glue into it, dried it, put it back, & ITS BEEN WORKING SINCE THEN ! It was a hardware fault, its not software !
Just my two cents, it worked in my case, I cannot guarantee if it will in your case too, try at your own risk !!

Same issue with SGH-M919. I was rooted and the rom I tried to use wouldn't work because the kernel caused some issues so I figured I would go back to stock. The device wouldn't go into recovery mode, so I flashed the stock rom via Odin. After the ROM loaded, the phone reset and I saw the Samsung screen then it rebooted and so on each time. It's not the power button as it works, has the spring feel to it and the phone would come one by itself if it was broken. So what can I do or am I in trouble?
Also, the phone will vibrate every 2 seconds

Sure, the power button will "work", but if it's constantly vibrating and rebooting, it's probably an issue with the power button. Do what it shows in the video I posted, and if you do it right it'll probably fix it. I gad to attempt it twice as it didn't fix it the first time, but it's been like 4 months and I haven't had an issue since.
Thank you but it was the kernel causing problems. Somehow, the new ROM messed up the partitions and subsequently required a full wipe including all data then I flashed the stock ROM back via Odin and it was fine. I rooted it again and flashed Bliss Pop 1.8 and I love that ROM. No issues at all. Thanks for the help. I'm slowly learning about ROMs and Linux etc.. I appreciate the help. Does anyone have any advice as to how I can learn more??? Where do I post to get past this 10 posts rule???

Wow I just realized that post was from a week ago and that was for my girls S4. We got rid of it anyway. My response was regarding my Sprint LG G3 which I am slowly mastering.
Same thing here but here i have a Lenovo …idk what to do

[Q] brand new g2 screen issues - lines down screen??

I JUST got my LG G2 from sprint less than 4 hours ago and as soon as i got home i rooted it using ioroot25 that i found somewhere online (if its important i can dig up the link but figure its probably irrelevant) and installed TWRP recovery, made a backup, not a single issue, then all of a sudden half hour later i pick it up and turn it on and the screen is mostly white with yellow lines (that move/respond to touch and whats supposed to be going on on the screen) and it will not show any sort of picture just kinda yellow fuzz lines...it looks just like some phones ive seen with cracked/ faulty LCDs but if i hold the power button and up or down to hard reset it, the LCD starts working again upon boot, and continues to work untill the LCD turns off for the first time after booting and i try to wake the phone again, every time i turn the screen on when its on it goes back to fuzzy lines with no way to make it start working other than restarting the phone with the buttons on the back.
anybody ever seen anything like this before? it cant be a broken or cracked lcd cuz when it first boots it shows a crystal clear screen and everything works fine untill the first time the screen turns off...im guessing i am more than likely going to end up making a trip back out to the sprint store tomorrow for a manufacturer defect replacement? any insight into this strange problem would be greatly appreciated!
