[Q] Screen Black But Touch Buttons Lit?

I thought I had a bricked infuse...but after unnecessarily removing the screen/components from the plastic casing and reassembling it, I tried recovering it again. I was FINALLY able to get it into download mode and then heimdal one click it back to stock. Everything went smoothly, but now when it "turns on" (I'm guessing), only the touch buttons at the bottom light up and respond to touch. The screen is absolutely black, except for the random FLASH that lasts a quarter of a second whenever I pull the battery and try rebooting it.
Has anyone ever had this problem before? I'm at a point where when it's on,( or at least I think it's on?), the touch buttons will light up and seem to respond to my touch (dim when touched). No vibrations of any sort though.
Please help
PS: If it is of any use..I used CM9 before all of this happened and I initially attempted to wipe it back to stock multiple times in the past, each time resulting in a frozen ODIN wipe. When I disconnected the phone during the process of wiping it, it no longer turned on or responded to charging the battery (I now have an external battery charger).
Also..when it is connected to my windows laptop, I get an error saying the USB device is malfunctioning.

At the very least it sounds like your internal drive is messed up. Try using the back to stock again - you could even try Odin again. However the problem could be more severe than that. You may want to make sure you reconnected all the components properly. One slightly loose connection can cause problems like you're having. I'm thinking that you might have a loose screen connector.

Also.may have something to do with that...not saying it is but that's a possibility, if you were to.rough with something or gave off a static discharge (computer motherboards are extremely sensitive to static...I'd assume mobile motherboards are too...)
Anyways try running Odin/heimdall again...

My Infuse is doing the same thing, black screen, but touch buttons on. Every once in a while the lock screen pops up and you can get into the phone, but then it goes black again. My phone is not rooted and we haven't done anything except install some programs, but nothing recently. It only happens intermittently, so I think this may be a hardware related problem, but it would be great if anyone has any other ideas on the cause or a fix. Otherwise I suppose we'll have to see about having it repaired or get a new phone.

i727 skyrocket stuck in continous reboot loop and doesnt get past start screen

I I have a Samsung Galaxy S2 Skyrocket i727 (with stock firmware and ROM), i dont have a SD card and not too many apps installed either, maybe 10-15 apps at most. Today while the phone was in my pocket it just went into this continous reboot cycle, it reboots, gets to the AT&T splash screen and then reboots again and then this goes on forever.
I googled the hell out of this issue but cant seem to find a solid solution and hence hoping u guys can help.
I cannot get into recovery mode cause it never gets past the splash screen
I cannot seems to perform a hard reset (power button + volume key) , it just reboots again.
I tried plugging the phone and connecting via USB but it doesnt help either, it reboots before the computer can detect the phone.
Hope u guys can help ? life without android is no fun...

I had this same issue with my LG Phoenix, I tried the needle around the power button, and that popped it back to normal. Apparently I held the button down to a side and it got stuck even though the actual button part was in it's "normal," position.
However it did reboot several more times after I got it unstuck. I did remove the back & battery, & unplugged it. Let it sit for a few minutes, after that I put the USB cable back in, then pressed the power button, put the battery back in and pressed the button again, and it went through the normal reboot process.

Just wanted to give you guys an update that i started cleaning the part around the edges as some folks suggested and that failed. then tried smacking around and blowing air into and that failed. Then took the entire phone apart and cleaned it several times using different techniques and sad to say that it all failed and i m SOL.
Bummer but it is what it is and i was quiet happy with that phone.

Where does one find a power button for the skyrocket (the one attached to the motherboard)? The closest thing I could find was this:
http://mobiletechvideos.mybigcommerce.com/samsung-galaxy-s-ii-skyrocket-power-button-repair/
It is a repair service though and I live in Canada, I would prefer if I could just order that part. I have been to few repair shops that cant do anything because this power button is hard to find. I opened up the motherboard and the power button clicks fine, so I think it probably has to be replaced.

Freezing the phone
I had the same issue, came here and read all the things about the stuck power button and needing to replace whatever is beneath it. My friend works in aerospace and had told me about one of the things they need to worry about is temperature causing wire shrinkage due to temperature. For whatever reason, I decided to use that logic and throw my phone in the freezer wrapped in a dry rag. 30min later and the phone finally worked after 8 hours of the boot loop/no boot. That was around November and I haven't had an issue with it since (until today, but it is a different issue).

I have just fixed mine!!!!
There is a little battery on the circuit board when you take apart the phone. It looks like a small watch battery. Top side is and bottom side are opposite polarities.
I had the exact same symptom. Sometimes just pressing the power button momentarily would bring up the power down menu, then I knew to press it a bunch of times because it was stick. If I didn't eventually it would turn off and vibrate constantly. It kept getting worse.
I measured with an ohm meter and the button itself seems fine so I figured maybe the digital logic relating to the button itself is faulty. So I shorted the little battery on the board (do this only for a brief period, no more than 1s) and put it back together.
Its behaving perfectly normally. I was also getting weird artifacts during video playback before, kind of like what failing solder would do on a bga gpu. It fixed that too.
So I think its similar to that problem some laptops have, where it wont turn on until you remove the battery, hold the power button down a couple times, and then plug it in. It seems a complete circuit discharge fixed this problem at least for me.
If people are interested I can try to find a picture
removed link
In that picture its the silver shiny metal circle. To short it you connect the bottom soldered part to the metal plate on top of the battery. This comlpetely drains all circuits.
So I think a lot of these problems are caused by a phantom charge. In any sense, Im very very happy
Also this could explain why the fridge method worked. Cooling the battery can significantly drop its charge, however I would advise against the cooling method if possible.
EDIT: blah cant post links... if anyone needs the image pm me your email

You'd need to find a friend or local electronics repair shop, but I ordered some here:
http://www.etradesupply.com/oem-samsung-galaxy-s-ii-skyrocket-sgh-i727-power-button.html.
The buttons are $0.99 USD if you buy 2 or more ($1.05 CAD), but 5-7 day business shipping is like $16.99. Still cheaper than a replacement phone, and it's an easy fix for an electronics person or electronics/tv/computer repair shop... At the rate these power buttons have had reported failures, and for the price, I'd get a couple of them in case the replacement fails in the future...
If my wife keeps squeezing the power button on her phone when some crappy app she has wigs out, I'll be needing my second button sooner rather than later...

why when one person says it something everyone band wagons on that idea. i actually had the same issue my skyrocket couldn't go pass the "samsung" screen. all i did was flash a new rom or i just restored an old backup

Then it was user error or a bad flash. And that's software, not hardware.
Skyrocket power buttons are known to fail. I believe Samsung has even acknowledged this.
When your phone randomly goes into a 1-second vibration cycle, sometimes showing the reboot menu beforehand without pressing the button, more than likely it's the power button that has either failed or is sticking.
With my wife's phone, the button was not sticking, and usually lightly tapping the phone at the right angle on your lap or the counter would break the vibration cycle and let it boot up, until the next random power button press and vib cycle would happen.
Button replaced, same exact ROM, and problem gone. :thumbup:

I have a repair shop and i fix these issues with no problem. the only issue im located in Puerto Rico. when the power button gets stuck is because of heavy use, a fall or something that makes a lot of pressure to it and the copper contacts inside the button stay making contact. this is know to happen to i727-i717-i997-i897 and some other galaxy s1 s2 models.
i attached the picture of the power button.

[Q] G2X screen not visible

Afternoon all. I know the title might seem like a BSOD post but my situation is different. I've searched but can't come up with anything.
When I turn my phone on, it completes the boot but the screen never appears. How do I know it's on? Three things, the ROM I'm using, Eagle'sBlood I think, has an engine revving theme instead of standard Android chime. Second,the menu, home, back space and search buttons on the G2X body illuminate. Lastly, if I swipe in the area where I think the unlock icon should be, the phone unlocks. If I hold down the power button and wait for the shutdown notice, I can guess the 'Do You want to shut down' and 'confirm shut down' icons and the phone turns off.
I've tried removing the battery, SD card, sim card and rebooting in each variation but with no luck. The phone has been rooted for over a year and so I tried booting into CWM (powerbutton, down volume). I think I'm getting into CWM fully but without the ability to see the screen I can't navigate.
This started happening yesterday. I was listen to Pandora and using a GPS app to track my run. The battery died during. I plugged it in for several hours but haven't seen the screen display since.
Any suggestions? If this is a hardware issue I'll get a new phone but without being able to see the screen, I'm not sure how to diagnose the problem. Other than rooting and changing the ROM, the phone is stock. The issue I had before this is the battery icon doesn't display. It just shows a battery outline with a ?-mark inside. The battery level only shows when the phone is charging and powered off.
Your help is greatly appreciated.

Really sounds like a dead lcd or maybe just the backlights. I don't really know how the backlight works on this phone but typically if there is video but no light you can put a flashlight onto the screen and barely make out the display around the flashlight. Either way it sounds like hardware.

Twitch - Thanks for the reply. I'm not 100% sure what you mean by backlights though. When the phone is on and the screen is not asleep I see lights around the edges but the screen itself is black. For my own knowledge is LCD and 'digitizer' synonymous? I saw another thread describing how to replace the digitizer for $60-75.
I'll try checking it with a flashlight when I get home.

I know there is an opinion thing but what is a good upgrade from the G2x for a non-hardcore user? I rooted and changed the ROM b/c you guys made it so easy to do, not b/c I was looking for the phone to do more than it already does. Up until this, and the battery display issue, and a wifi issue I forgot to mention, I've been happy with the G2x but there is no reason to spend $100+ repairing a 2+ year old phone that I pickup used off CList in Q1, 2012 if I can find something better on the used market for $200
maurice

Yeah I'm not too sure how these phones are set up, I have more experience with lcd monitors and such. But I think it is all in one piece on phones.
If you're looking to upgrade pretty much anything that came after the g2x likely has a lot more to offer in development. Good thing about this phone is everything is an upgrade. I have a samsung galaxy s 4g that's nearly 3 years old and single core but it runs 4.3 like a boss! Aside from GPS...

Flashlight didn't show any screen images. I think the next step is just trying to guess my way into debug mode and connect via uSB to my laptop and retrieve data before dumping the phone or trying to replace the lcd/digitizer. I saw an app mentioned in another post that should allow me to mirror my phones screen on a laptop. We'll see.

last chance
Last chance in case anyone has any great ideas. I'll be ordering a new LCD and digitizer (probably don't need both) but would prefer not to spend the coin if that isn't my problem. all suggestions welcome

Hmmm, this an odd and aggravating problem you have here lol. I've ran two versions of eaglesblood, their CM7 version on 2.3.4 and their ICS AOSP version on 4.0.4 and have never heard an engine revving in any boot animation so I'm not sure what rom you're running either. Have you tried the hard reboot? While the phone is on at the home screen (if you think you're there I guess) hold the power button and the volumeUP button and the phone will reboot. I've read on here from a more experienced user before that doing this clears or does something to the caches that makes for a more complete reboot or "reset" of the phone's condition. Try that and see what happens. The only other option I would try to take is to flash a new rom and before doing so doing a COMPLETE wipe (to include format /system) and full instillation of a new rom, gapps and kernel. Can you see any images if you boot into CWM when shining a light on the phone's screen?

Maybe I'm wrong about the ROM. The flash screen shows the android graphic in electric blue and a comet type animation zooms around. During the zooming, the sound is an engine revving. I was using the ROM for 2-3 months before this issue popped up so I doubt it is the cause just wanted to give those more knowledgeable than myself as much info as possible

That's my real problem, I can' t see anything! With the phone on, when I hit the power button and unlock the screen (guessing), the only illumination is the menu, home, back space and search buttons on the G2X body. I can tell from the haptic feedback once the phone is unlocked and I can occasionally guess the proper location to shutdown.
I tried the hard restart (Power, Up) but same result. I've downloaded an app called MobileGo for the computer that displays the phone screen but I can't get USB debugging turned on.
I have noticed another odd issue. With the phone turned on and the SIM card installed, when I call myself from a LAN line it goes straight to vmail. I know the SIM is good b/c I've been using an old nokia candy bar phone with the same SIM while troubleshooting. When re-inserting a SIM card, is there anything the user needs to do for the phone to recognize the SIM? Just wondering if this 'direct to vmail' is another sign of ............something.
Thanks

Sometimes when I take out the sim card my apn gets messed up. Ideally you'd just go into settings and load default apn and it'll work again.

But calling should work.
Seems like a busted screen from everything being described here.
Try connecting to a tv using hdmi... maybe the ROM would allow it to display. Worth a shot.

It's alive!!
My phone is alive, or at least it was.
I followed the directions on the youtube video I found to take the G2X apart and the first thing I noticed was the corrosion on LCD connector. I'd already purchased the LCD so instead of cleaning the old we just replaced it. The new screen worked, unfortunately I couldn't get a signal so we took it apart again to clean off corrosion on all the connectors. I'll let it sit for a few days to make sure everything is dry.
Don't be a fool like me, if you're going to do anything with your phone that might cause it to get wet, especially sweat, put it in a baggie or something. I'll post a follow-up if the thorough cleaning does any good.

I'm pulling for ya man, best of luck!

It works!!

For anyone else that runs across this thread, unless the digitizer or LCD is physically damaged I'd disassemble the phone and check for corrosion before buying new parts. I used the new LCD but that b/c I'm not going through the trouble of returning a $16 item.
Wi-fi still doesn't seem to be working, which is odd. Wi-fi stopped working two months ago, it doesn't even show available networks, but worked for a few minutes when I originally replaced the LCD last weekend. Both antennae are connected but oh well. if I had to choose network vs wi-fi connectivity, I'll take network!
Thanks again for all the help

Nexus 5 screen died today + dangerously hot lower screen

Went to unlock my phone this morning off the charger and the screen is totally dead. Couldn't unlock or do anything to it or even see what was going on, called Google and ordered a replacement ASAP.
Went through the not fun task of doing a nandroid backup without seeing what was on the screen and doing some trickery with screenshots then backing up my entire SD card.
However, here's the strange and potentially dangerous thing that I noticed later when I got home this evening. I went to look at the phone and go to a fastboot flash with the factory images and went to touch the bottom of the screen. When I went to do so, to the little bit of the left of the LED light was a SUPER hot portion of the phone. I almost burnt my finger it was so hot.
Not sure what to do about the issue, I feel like if I just call the support line they won't actually take in my concern legitimately. Any suggestions?

thats something quite strange
let us know what google says about RMA and this issue

Agree, maybe it's just your phone, maybe it's all the batch. Which batch/model do you have?

On my Transformer Infinity, sometimes the screen won't turn on at all. On a few occasions, if I press Power enough times, I get a glimpse of a message saying the Launcher process has stopped, but then my touchscreen doesn't register any input. The tablet is also sometimes running quite hot at those times. The only way I know to recover from this is press the Power button long enough to force a reboot, then everything is normal. Could this be what's happening? Do you know if the phone is still running under the black screen? Have you tried forcing a reboot, and did it work?
As for the hot phone, I've noticed my N5 does get a bit warm when I'm using it intensively (4G, WiFi, Bluetooth, GPS and screen on all at the same time and in use) but not enough to burn me. Could be hard to tell which component is heating up like that since I think it could be the screen backlight, SoC or battery... Do let us know if you find out more.

I had called them and reported the screen totally dead with lines streaking vertically and got a new replacement ordered. It wasn't until late last night when I got back and had the screen on in this dead mode that the bottom was extremely hot. I'll have to call them back and let them know

Yeah, no its definitely dead. There were streaked lines across it, rebooted it multiple times. I ended up going into the bootloader and recovery via adb/fastboot and all that jazz. It eventually just would not work now.
In regards to the hot part I definitely think it was the lower part of the screen. It was quite literally half an inch away from the LED to the left. Was super super hot then once I shut the defective screen off (I could tell by the backlit light or whatever) it wasn't hot anymore after a minute or so.

Is it black/white? 16 or 32? When did you get it?

32gb black version. I ordered it immediately when they announced it that day.

mine gets really warm when i'm doing a TWRP backup then it goes into bootloop after and wont cool down. i have to force it to power off from recovery and let it cool, but i've always seen it happen. i wonder if yours was attempting to boot over and over for hours and cooked itself.....? i have a launch day black 32gb too, running Cataclysm with Franco at the moment but it was doing it on rooted stock with stock kernel

I had to send my 19 day old 32Gb Red Nexus 5 in to LG for the same reason. I was using the phone and all of the sudden had vertical lines and the bottom of the screen got burn your fingers hot. Waiting to see what LG does with my phone. The only thin I can figure is the synaptics chip which controls the screen is bad. Its the only thing in that area that could get that hot. I also noticed when I first got my phone the glass in the same area looked like it had a slight wave in it. Didn't think anything of it at the time. I'll let you know how it goes.

Is RMA/replacement applicable for Rooted and unlocked devices?

I don't believe its an issue with developer phones as long as the issue wasn't caused by something you did like brick it by flashing a wrong radio or something like that. It has to be a manufacture defect to get it fixed for free.

My device issue is related to power button. there is no software issue.
The power button is rattling since from the purchase of the device.
Hope my device gets repaired.

Screen randomly turns off but phone still on, backlight often stays on

Hey guys, i'll try to explain the situation as best i can below, hopefully someone can work out what is wrong.
My phone is about 16 months old. About 2 months ago i dropped it twice within the space of a couple weeks. There were a few cracks along the screen, however it wasn't very noticeable and i wasn't going to bother having it fixed. The problem started a couple of weeks ago when i went to grab it out of my pocket, however i found out the screen was black and it wouldn't turn on. I don't really know how to describe it but it was acting very strange...
- The screen would have white/gray bars all over it then turn off, then it would do the same with very thin vertical lines that were white/gray/other colours...
- When i get the screen on, it generally turns off again within 30 seconds, however it can stay on for a few minutes.
- If the screen is on and i press the lock button, it almost certainly won't come back on.
- Restarting the phone or holding the power and volume button nearly always gets the screen to come back on. It often then restarts but turns off again shortly after.
- The phone is otherwise still working when the screen goes off; the notification light stays on and i hear messages etc coming through
- The backlight often stays lit, revealing a gray screen opposed from total black. Sometimes it does not stay lit however.
- When the screen came on it was often unresponsive to touch
I had the screen replaced yesterday by a phone repair shop and the phone is still not right. I have factory reset the phone and also wiped the partition cache. Other than that it is still not working. IT seems to be working better... The screen always seems responsive to touch when it is on, and it doesn't seem to be turning off as often. It generally starts up and works fine when i start up by holding the power button and down volume button together... However even still it sometimes just flashes up with a few thick white/gray and black lines on the screen..
Does anyone know what can be causing this and how i can resolve it? If you need any more information please let me know and i will try provide it. I could try get some pictures of what the screen is doing when i finish work. Thanks guys, i appreciate any input.
EDIT: I managed to get a pic of what i mean by the thin vertical lines all over the screen. This just appeared when i tried to restart the phone after it the screen had once again stopped working. The imgur link is gIFMGD6

Anyone have any ideas?

Hey, did you ever figure this problem out? My phone just started doing the same thing. Can't find much info about it.

Yeah, i had the screen fixed hoping it would fix it, however that didn't work. Turns out it was the motherboard, don't know what was wrong with it in particular other than it was simply going faulty. Had someone replace the motherboard on it for $50 and have had zero problems since! Hope that helps you.

Thanks for the response. I tried replacing the screen too with no luck. Unfortunately the same place that replaced the screen said it would cost $400 to replace the motherboard!!! The phone cost less than that so it looks like I'm gonna buy a new one.
