[Q] Screen doesn't turn on

My phone was working perfectly fine and it's never done this before. I sent a text and then it was sitting on my desk for a few minutes. Heard the notification sound for a new text message and when I tried to check it the screen wouldn't turn on. The buttons at the bottom still light up and the notification light works. I tried removing the battery and turning it back on and it makes the start up noise and vibrates but the screen still doesn't show anything.
Anyone else have this problem and know how to fix it?

Don't quote me but that sounds like a flex cable

I have that issue sometimes. I just flick my screen really hard

I don't know what's wrong with my shift I've had issues with it for a long time, it goes black heats up like none other and the screen won't work but the home menu back and search are lit up. So I let it cool power it on and flick the center of the screen haha

to me that seems like a deep sleep initially but the center situations is definently wierd..my shift has never really had problems when my wife had it she hated it cause the battery would be dead in like 2 hours

It's not deep sleep it's the flex cable.. My old shift had the same issue. Just keep messing with it and eventually you should be able to get it to work long enough to unrooted it if you need to take it in. Try booting into bootloader and see if the screen loads. I know it sounds weird but when my screen went out it wouldn't show anything not even the splash screen but bootloader would show up just fine.
Edit: Another thing is if bootloader shows up go into recovery but you'll need adb if the screen is blank. Find a PG06IMG, example the froyo one, basicly anything that is stock. Next enter these commands.
adb shell
# mount /sdcard
# exit
adb push PG06IMG.zip /sdcard/PG06IMG.zip
adb reboot bootloader
Now you should be able to accept the update :beer:

It's the Flex Cable. I've done two this week with the same thing happening.

Skyrocket randomly restarts and vibrates at 2 second intervals?

This has been happening for a few days now, the phone turns off and endlessly vibrates until I pull the battery, and then it does it again and again but it'll work for a few hours before it happens again... I've tried different roms but its still happening and it's getting very frustrating

does it do it on stock? And are you over clocked?

You mean like physically? Seems fine the phone just starts doing it randomly while it's just sitting on the bed. Right now it's not even turning on at all no matter what I try :/

Here is one example:

It's in download mode now, I'm going to try downloading stock Rogers ICS and see if the problem persists, if it does I still have 5 months of warranty so hopefully that'll be covered

Ok. You can try jamming on the power button repeatedly too...
Good luck!

Looks like the skyrocket's done for good.. I'm going to take it in to the store tomorrow but what do you think they'll say when they fix it and find out it's rooted?

no.
try this test, when it goes through the bootloop, keep the power button depressed w/out releasing it and see if it displays the same charactersistics as your bootloops, also count the seconds each situation has, if they are the same then the problem is the sticky power button

It's the power button that is messed up, hands-down.
Try and try and try and sooner or later you'll probably get it. I could care less about the phone as I have a replacement coming, but I wanted to get my data off of it.
Open up you're phone if you're comfortable and mess with the power button directly some, either you're going to fix it long enough to get your data or break it completely...doesn't really matter at this point.
Just put the battery in and right after the phone vibrates hold the power button and see how lucky you are at getting it to last the full 8+ seconds instead of the usual 2 before it reboots and vibrates.
Once you get it working, don't touch that *****. As gently as possible, set it down and get your USB in, turn on Mass USB and debugging and copy your stuff. Put the timeout to the max or download an app so you don't have to touch the power button ever and just touch the screen every once in awhile if you don't have an app. Don't forget to reset your flash counter and reflash stock ODIN if you're rooted or on anything custom (Use ADB to reboot through all this)
Honestly...I let my phone restart on its own for a total of like 8 hours (I didn't care and honestly hoped it burnt up or something and was completely fried) and I watched it for a good chunk of the time and it never booted up on its own. After I took it apart twice and beat the hell out of the power button a good while I finally got it to work.
Repeatedly mashing it after 'attempting' to clean it and then pulling the battery/reinserting and seeing if it worked is how I finally got mine.
Now it's just a paper weight till the new one comes.
Edit: I find it weird that a lot more of these problems are popping up. I noticed a bunch of threads on various sites towards the end of June that had popped up and now some are here too recently. I guess the Skyrocket's cheap-feeling Power Button is indeed...cheap.

It isn't the power button. I posted this problem months ago and took it in to a device center. It was actually a battery issue where it connects into the phone. The charge going into the phone doesn't stick, causing it to flicker power and thus restart constantly. They never ended up getting my old one to turn on and never saw it was rooted and what not. Ended up just giving me a refurbished one.

well if it never turns on, then its not the sticky power button problem, the sticky power button has a reboot symptom at a consistent interval

Alright, I will definitely try and try until the phone turns on before taking it into the store. This has actually been happening for a few days now but I didn't really care too much because I was really busy and I thought since it turns on after a few tries, I'll just take the files off and return it to stock later. Also, yesterday someone gave the suggestion of repeatedly jamming the power button and that actually worked twice but after that it never worked again.
Is it possible to remove the back and fix the power button without voiding the warranty (are there any stickers)?
EDIT: I have it disassembled right now, what exactly should I do to the power button? I tried clicking it a few times and blowing at it nd I put the battery in but still the same thing
EDIT 2: Umm what looks to be the litmus paper on the inside is red.. the phone has never come in contact with water so how is this possible..
EDIT 3: Every housing I've seen online (4-5) has a red square on the housing so I'm guessing it comes in red by default? Either way I'm taking it to Rogers right now, they said I could have a refurbished for 35 or I can just repair this one so I'm just going to repair it and hopefully the files will be preserved.
My only concern.. the phone running Juggernaut 5 right now LOL and the internal SD is full of rom zips and kernels so hopefully they don't look at that, or don't care. Once they repair the phone, what can they really do tho? Break it again nd send it back? haha

I would just fiddle with the power hoping for the best.
As far as your roms go, I doubt it'll be a problem. A) They're not going to get the phone to turn on anyway. They're probably just going to repair the button and reflash before they even check anything. Either way, like you said, the worst case is they find it but you already have your replacement...maybe they'll try charging you the phone, throw a hassle and offer to cancel your service and tell them to send you your "unwarranteed phone" and the button repair bill and they can have theirs back. I don't seem them getting you for it. All they might do is check the flash counter which probably hasn't been tripped if you didn't use a bad ODIN.

Flash counter is at 0, I checked when I managed to get into Download mode before it stopped working altogether. Juggernaut 5 is a rom for the Hercules (T989) and that's not the problem, I've used it before and I only flashed it after the problem started because I thought ICS was the problem, but it stayed even after flashing Juggernaut.

so what did u end up doing, fool around w/the power button or did u bring it in

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] Power button broken, need help/advice

Hello,
So last week I woke up and my power button stopped working. I looked around for similar issues and found quite a few stores selling a power flex cable (I attached a picture of it because I am a new member and cannot post the URL for the site, but it's easily found using google)
Since it was only six dollars, I ordered it without much thought. Just looking at the cable, it looks like it would fit into a connector rather than needing soldered onto a board, so I figured it would be pretty simple.I finally received it, and after looking around at a bunch of teardowns and the service manual, I do not see this cable or connection anywhere I was going to just open it up and check it out, but didn't want to risk not being able to turn the phone back on.
I am looking for advice! Specifically, if there is a way to power the phone back up without having to use the actual power button, I'd love to know.
FWIW, my phone is not rooted and factory stock
Thank you!

Bumping because I would really like to get this fixed! Not sure if this may go over better (or would be appropriate) on the i9300 forum.
Any help would be awesome!

Back up your phone in the way you see fit. Try and fix button. If you fix it yer done. If not buy a jig. The jig will get you into odin mode. Plug phone into computer. In odin make sure that auto reboot is checked. Flash something like a recovery. Once it finishes flashing it will auto reboot. Enjoy.

Use the home button to wake and a gesture gesture app to put a custom action to turn the screen off. Or put a screen off action on your home screen. Wherever you want

Busted phone for a Dev if you want it

Alright guys, I had a conversation in Ax's "Run ROMs on different Carriers" thread, but I really want to get to the bottom of my issue, whether it be a hardware issue, ROM related, OR user related.
I've been having an issue with my phone the past few days. Started out it would read "invalid sim, need to reboot" or something along that. Anyways this was after flashing a nightly and I figured, OK, it's a nightly i'll live with it. Eventually my phone just started to power off/reboot all by itself; not real consistent but it was happening more than I would like. Today, the S*&% really hit the fan. I flashed a nightly Wednesday night(i'm not going to say which one, because i'm not sure if it was from the ROM itself or if this was a hardware issue). Anyways, Friday at about noon or so, I open a game to play on my lunch break, I get distracted so I lock my phone to attend to something else. I go back to my phone and it is powered off, now totally unresponsive to anything. I pull battery and try to restart, when I place the battery back in the phone it automatically reboots(WITHOUT ANY BUTTON PRESS) I thought to myself ok this is kind of weird. I try rebooting by using power+vol up...absolutely nothing, it's just a brick. Well, I pull the battery again, hold vol up thinking it will go into recovery...nope, it will boot for a sec or two, just enough to get the blue lettering on the top left of the screen then shuts off again. OK, let's put this b*&*h into download mode and see what happens. it goes into DL mode, all the way to the point of where it says " do not turn target off" then shuts down. I did both of these multiple times, with different batteries as well, plugged in and not. It won't stay on for a computer to recognize it. Someone suggested a stuck power button, I don't think so; it feels the same as it always has.
I was fortunate enough to be able to get another S4 with a busted screen so I switched out motherboards. I have a working phone again...which is all I was worried about. I've flashed quite a few ROMs, I follow procedure to the T when flashing... What do you guys think...hardware issue...user issue...ROM issue? I'm very curious to know because I don't want this happening again, obviously. I would even send the phone out to someone to play with(mind you, the screen doesn't work and the silver bezel is crappy because I just used my original one).

I would say stay away from whatever ROM you flashed. This could also be a hardware issue. I had my old note just randomly shut off on me and was unresponsive as well. Finally got it to boot and reset it. But in your case I would stay away from that ROM and maybe find something more stable. So as this is unknown to what happened I would not blame either. Sorry to hear about your bad experience.

Alright guys, I had a conversation in Ax's "Run ROMs on different Carriers" thread, but I really want to get to the bottom of my issue, whether it be a hardware issue, ROM related, OR user related.
I've been having an issue with my phone the past few days. Started out it would read "invalid sim, need to reboot" or something along that. Anyways this was after flashing a nightly and I figured, OK, it's a nightly i'll live with it. Eventually my phone just started to power off/reboot all by itself; not real consistent but it was happening more than I would like. Today, the S*&% really hit the fan. I flashed a nightly Wednesday night(i'm not going to say which one, because i'm not sure if it was from the ROM itself or if this was a hardware issue). Anyways, Friday at about noon or so, I open a game to play on my lunch break, I get distracted so I lock my phone to attend to something else. I go back to my phone and it is powered off, now totally unresponsive to anything. I pull battery and try to restart, when I place the battery back in the phone it automatically reboots(WITHOUT ANY BUTTON PRESS) I thought to myself ok this is kind of weird. I try rebooting by using power+vol up...absolutely nothing, it's just a brick. Well, I pull the battery again, hold vol up thinking it will go into recovery...nope, it will boot for a sec or two, just enough to get the blue lettering on the top left of the screen then shuts off again. OK, let's put this b*&*h into download mode and see what happens. it goes into DL mode, all the way to the point of where it says " do not turn target off" then shuts down. I did both of these multiple times, with different batteries as well, plugged in and not. It won't stay on for a computer to recognize it. Someone suggested a stuck power button, I don't think so; it feels the same as it always has.
I was fortunate enough to be able to get another S4 with a busted screen so I switched out motherboards. I have a working phone again...which is all I was worried about. I've flashed quite a few ROMs, I follow procedure to the T when flashing... What do you guys think...hardware issue...user issue...ROM issue? I'm very curious to know because I don't want this happening again, obviously. I would even send the phone out to someone to play with(mind you, the screen doesn't work and the silver bezel is crappy because I just used my original one).

Im saying nothing for sure, but a stuck power button feels just like normal. I had this issue on two separate samsung phones (they are known for this issue). I thought it was just bs, but i decided to tear it down and check. I used a q-tip and everclear and got plenty in there, wiggled and pressed the button for around five minutes. Re assembled, put the battery in and sure enough, the problem was gone. You cant always feel the button sticking. But hey, if you are offering the remains up, ill take em! I would gladly pay $200 for a replacement screen for it to test on.

Someone beat you to it, Rebel, sorry...just took the first poster or PM that I got. I got the message overnight otherwise I would have posted in here.
I kinda played with the power button when it was tore down, however I didn't use any alcohol on it but that is a good idea.

Edit: Used some IPA on the power button this morning, soaked it pretty well, pressed the button many many times with varying pressure, with a hard pointy object etc. etc., jiggled side to side, tried every option I could to get it unstuck (if that's what it is) and still doing the exact same thing.

Mods, I'd like to politely request this thread to be closed...no use for it now. Thanks.
