Broken screen or what?

A relative of mine also owns a G2 but recently they experienced a weird issue. They just picked up the phone just to see that the screen went bad. Wasn't in the process of flashing anything. The phone ran CM7.0.2 for the longest time. It was all black with a white line running across the screen and the capacitive buttons are stilll lit. After a week or so, the white line disappeared and its just a black screen now.
There's no water damage as it went nowhere near water and the water damage indicator is still white. Could the screen be broken? A loose connector? Any help?

I don't know much about the g2 but try and enter the bootloaders. If they come up then its programming. Something like that happened to my hd2 cuz a bad flash.
If they don't then its prob the screen.

You think just ordering a new screen from Amazon or eBay and replacing it will do trick? And yeah I just thought about bootloader as I wrote the question.

if it ran a long time i would guess a hardware failure (if it doesnt even show up bootloader)
so you need to replace the display.
does the display even initialize when powering up the phone?
when switching the phone on you see its "switching" from black to dark gray (lighter black as it is when powered off)
cause if it doesnt even get power, it could be something on the phone too which doesnt give (enough?) power to the display...

Yeah. but I'd take it apart if u know how just to check

Try to connect with adb just to make sure your phone is still working before you spend money on a screen. Unless it rings when you call it or something.

Screen randomly doesn't respond

Hi fellow PLAY owners, I'm having trouble with my screen. I can turn my phone off no problem, but when it comes to waking it up, either by pressing the power button or the home button, my screen won't turn on. I can slide it open, and i hear stuff going on as if my screen were on, but I can't see anything. It'll be like that for random amounts of time, like 1 minute, or as long as 5 minutes or more. Any ideas? THANks

That's the flexible cable problem...

I had the same problem..... and now it wont work at anytime... ); so am trying to replace the screen digitizer.

Alright, how about a little Xperia PLAY anatomy class lesson then? What does the flex cable do and what does the screen digitizer do?

they do different jobs

the digitizer lets the software know where you pressed on the screen, the ribbon connects the screen and digitizer to the main board of phone

So which one would it be if even pressing the power button, which is a harware button, doesn't respond?

Can anyone help me by giving me the part number I should order? I'm checking eBay but there's at least two options for the same named part... Thanks guys!

Is your phone underclocked while the screen is off?

mine has the same problem but i think there's only a dead spot. For example, the numpad place for 4, 5 and 6. Is there any way to solve this other than taking it to a technician? Problem appears at random times also. Thanks in advance!

I think this is a different issue. My entire screen won't turn on even though the phone itself is on.
By the way, my problem has gotten worse. Now it will only turn on (by chance) after I have slid out the gamepad. Grr..

As far as I know there is no under or overclocking going on. Not unless my ROM does it without me knowing it (Gin2Ics).

Anybody know the name for the flex cable part? Or the part number? Thanks/:cyclops:

So I bought this screen digitizer thinking that it was the problem... and it took forever to get delivered! anyways, I replaced the digitizer and am having the same problem.... :/ and after I changed the digitizer I noticed that the flex cable is actually ripped!! so now I purchased it from here and I'll keep u updated.

Hey thanks so much man. Hope it gets fixed. I want to know how it works for you so maybe I might do the same. It finally died out on me and screen won't turn on at all...

That's exactly what happened to me!

soo.. it finally worked after I changed the flex cable

That's cool man. Congratulations. I, unfortunately, didn't have the same luck. My phone is out for the count. I now have the sad news of no longer being an Xperia PLAY owner. Sad face.

I'll leave this question opened though, for others who might profit from it! :highfive:

Button Problems and First Root Ever

Hi, Everyone! This is my first post on here but I have spent the better part of the last week reading all the different threads. Yesterday my Samsung Epic 4G decided to go a little insane on me. It was working eprfectly fine (especially for a 2 year old phone) when all of a sudden my power button seemed to start cyling and the power off screen kept popping up and the volume keys did the same. I turned the phone off and even tried taking the battery out and giving it a rest but the problem persisted.
Another issue was that some of the numbers no longer worked correctly. The even numbers both on the touch screen and keypad would dial
"2468" instead of the corresponding number; very weird! The phone had never been rooted or modded at all. Well I was able to get into the phone after figuring out a way to input my passcode with the faulty numbers and I performed a hard reset. The phone is back to completely stock but the power button and camera button do nothing. The volume up button works well but the volume down (besides lowring the volume) button causes google search to pop up and then a bunch of letters and numbers to be typed in both the google search bar and in the message of box of the last person I texted. I can still use the phone by opening the key pad to wake the screen up and I can text and call fine as long as I don't touch the Volume Down button. Also, battery life is ridicolously low. I am up for upgrade but don;t really feel like upgrading to the S3 just yet. Sorry for the long post. I know it is against forum policy but I wanted to get the whole story out there. So here is what I am looking to do:
I want to root the phone and install one of the roms to maybe eek out a couple more weeks out of it. Again it works ok now, just the sliding out of the keypad and lack of power button sucks. The phone boots up if I take the battery out and put it back in wihtout touching the power button.
I have read up on Odin and that looks somewhat straightforward. Just trying to see what you think is my best course of action. Again, I do not have a power button working or camera button and a faulty Volume Down Button. Maybe I can do the whole slip in the battery while holding "1" to get it into download mode? This will be my first time rooting a phone so any help is great and appreciated. Thanks and again, sorry for the really long post!

I forgot to mention that the phone is currently running on Gingerbread 2.3.6. This may or may not make it more difficult to root.

Did the phone get wet at all? Use it in the rain?

was thinking this as well

It actually got wet about 1.5 years. I threw it in rice for about a week and never had any issues. The phone has never frozen or had issues the past year and a half. Yesterday it was in the kitchen charging (with a samsung charger but not one for this phone specifically) and it started doing the whole power button/power off screen flashing. I was able to get it in download mode earlier today but i don't know about recovery mode since the power button is dead. Maybe I should root it to see if its a hardware issue?
Edit: I forgot to mention that the phone gets really really hot while charging as well in the area above the battery. Hopefully nothing short-circuited.

It could take a while before the corrosin gets bad enough to affect your phone. I dropped a phone in the toilet once, and it was over 2 years before it crapped out. Took it apart and it looked like an old Chevy wheel well inside.

That is a good point. I never thought of that. It was also in the kitchen which was humid and hot as ever yesterday. Do you think any kind of root or rom could help me squeeze a little bit of life out of my old phone.

Doubtful. If you're hardware's screwed, so are you.

So I left the phone alone for a couple days with the battery out. I go to turn it on today and it worked perfectly. Then after about 5 minutes the power button stopped working again, but everything else is ok. No random letters and numbers and the volume buttons work as well. Now, I'm kind of lost as to what to do. I do have a parts phone, same one as this. Maybe I need to replace the power button? It clicks and everything and even worked for a couple minutes but now is non-functional again.

R800x bricked, please help

It seems I bricked my Xperia Play. It was working fine one day when it shut down due to low battery and wouldn't boot back up. I'm out of warranty, so tinkering around in the hardware is doable, I just don't have the tools at the moment. Anyways, with the battery in when I hold down the power button it vibrates roughly every two and a half seconds, but the screen stays off and the notification light stays off. Yesterday I was trying to make it boot, and I believe when it was connected to a PC, Windows defects it then it disappears when I hold down the power button, as well as the notification led blinks red/orange a couple times. Unfortunately I had to cut my troubleshooting time short(Rush concert ftw), so I was unable to do much research. However, I did a little and all the things that I found said that it was infact a hardware issue that requires manufacturer fix. Seeing how that's not possible I came Here hoping that one of the geniuses at XDA could help me. Help?
For the record its not my phone anymore, I gave it to my sister and she had about a day of use before it broke, and before they I let my friend borrow it so I don't know what she did with it, but she's fairly trustable, so I don't think it was something she did.
For those wondering my current phone is a broken Galaxy Nexus. Don't worry, I'm ordering a replacement tomorrow,

[Q] Phone won't turn on, blue led light stays on

Hi everyone,
This is my first post and I hope I won't somehow piss anyone off. I'm just looking for a little advice or guidance.
Device: SPH-D710 Samsung Galaxy S2 on Sprint (CDMA). It was running the latest over the air ICS update. It was not rooted.
Background: Starting about a month ago the phone began to occasionally restart on its own. Also, my clock widget began to disappear randomly, no matter how many times I would put it back on the screen. It would also occasionally crash on resource heavy apps like chrome or facebook. I installed Go Launcher to try to fix the widget problem. This is the only thing out of the ordinary that I've done recently.
Problem: While running an app the phone crashed. I pulled the battery and restarted it. It never booted. The screen remains completely black and the blue LED light stays on. I've tested a different battery, it wasn't the problem. I've plugged it into my computer and it does not see the device. Plugging in the charger turns on the blue light (I can only turn it off by pulling the battery).
Question: I'm pretty sure this phone is bricked but would love confirmation (whether you can confirm or tell me how I can confirm). What I really care about is being able to access the data that was on the phone. Is there any way I can access the data? The sprint store said it would be 50 bucks to look at it and if they can't fix it they would get me a new phone. I really don't care about a new phone. Is there anything that they can do to recover my data that I can't?
Basically, is there anything I can do to access the internal memory files? (Secondary question is can I fix the phone).
Thank you in advance for your input and excuse me if I haven't followed all common etiquette on this forum. (I did search the topic).

Do not send it to sprint. Look up jtag. Send it to a reputable company like mobiletechvideos. They will repair it if it can be brought back. Solid blue light is bricked. Flashing blue light is a bad battery. Goodluck.

It definitely looks promising - if they can fix it, would it be fixed but wiped? My main concern is recovering internal data.

spoke to kyle at mobiletechvideos and he thinks it's an emmc failure since it wasn't during flashing - in which case my saved data is gone forever. anyone disagree or have any other insight? can i save my data?

Mine started the random reboots, and then reboot loops, then couldn't get the screen to turn on...blah blah blah... lots of issues lots of people have seen. It was all because of the power button. It eventually got to where it just didn't work at all, and i was smacking the power button corner of the phone on a table or something to even get it to power on, and having to use the volume rocker wake option to wake the screen. I'm not sure if your issue is the same, but it only cost me $40 to get my power button replaced at a cell phone repair shop locally and took the guy less than 30mins.
Just a suggestion, may not have anything to do with it, but it could save you some money it happened to work. Alternatively you could try smacking the power button corner of the phone on a hard surface a few times and if it is the problem, it might unstick long enough at least know thats what it is.
I'm no expert, and i make no guarantees or promises, just my experience with mine and my wife's phone over the last 2 years...lot's of issues solved by one of three things, power button, usb port, and battery. Good luck!

That is not the issue. This is an emmc failure for sure.
