Screen died?

Last night I was out and during the night I pulled my desire z out of my pocket to find that the screen was dead, the soft touch buttons were still lit up and working but no display. I pulled the battery and tried to reboot and no luck, you can hear it booting and even unlock/receive calls and txts etc once it has booted up just the screen stays blank the whole time so have to do everything on feel.
Essentially does this just mean my screen has a hardware fault? is it worth trying to fix? I assume the only option would be to purchase a replacement screen and dissemble and reassemble it?
(warranty is not worth it as I live in New Zealand and would have to send my phone back to the UK where I bought it from, also I have dropped it quite a few times so probably voided anyway...)
Thanks in advance for any input

Does it never display anything? So not even a flash during boot or something?
Because then it is probably a hardware problem.
Since the soft touch buttons do still work I think there might be a little crack or something in the flat cable that connects the bottom half with the top.
Maybe you could check whether you can see if the cable is broken or not?
The best thing to do then is to look for a replacement and try to fix it yourself or bring it to a shop where they can do it for you.

No it never displays anything, completely dead the whole time. The touch input is still working though as I answered a phone call this morning on it by making the usual gesture just without being able to see anything. Doesnt seem to be anything wrong with the cable itself as far as I can see. Yea might have to get someone to have a look at it.

My phone is acting the same. I dropped my phone in the pond before, but pulled battery out on time and had it in rice for a day. My phone was still working for about two weeks after that incident. I dropped it and had one little crack at the top of the screen and about a week after that it died when I had a water balloon fight with the phone in my pocket. D;
Do any of you know if the replacement lcd screen/digitizer for the Desire Z would work for the G2?

I had the same thing happening to my G2 screen, only it was intermittently working for a little while, then just completely died and wouldn't work. It was doing this crazy flickering thing then the back light wouldn't go on at all. If I held the phone at a certain angle in the sun, I could see that the pixels were indeed working on the display, but there was no backlight to make them normally visible.
So I purchased a replacement screen from ebay and carefully followed the directions on a youtube video for a G2 take apart. Its not a hard task to take apart and get down to the screen itself. It was rather easy. After putting it back together the screen still didn't work! Sounds work, i can also receive calls etc. But the screen still doesn't work!
Is there any way that this could be a software issue?

Oh and PS, I believe the LCD replacement would work for both the desire Z and the G2. They are identical phones after all right? I'd say its a safe bet. The screen I bought was only 35 bucks. Didn't think that was a bad deal.

Another dead screen or something else?
Few days ago my phone fell of the couch onto a rug - no big deal, so far it has survived much worse, but when I picked it up, the colors were all messed up - overly green and red. Tried restarting - no luck. Everything worked fine, except the colors, but then the screen turned of completely. I could hear notifications, phonecalls, but the screen was dead. After some tapping on the screen, it turned on again - with ****ed up colors. Then started flickering and was gone again. Few more times I could turn it on by tapping before it was dead for good.
Figured, after all these drops it survived, maybe the screen connector is a bit loose. I mean, I could sometime get a contact when tapping it, so I dissasambled it completely, secured all the connection, put it all back tougether and fired up - same thing: dead screen, phone working.
Has anyone had such problem before? Is it screen that is dead, or connector or... I have no clue... I would like try to fix it on my own, with some replacement parts I could get on ebay - but, what gave?

[Q] Where to get GNex's motherboard? Or in my case, do I need one? Details inside...

Hello Nexans,
Long story short:
I was applying SGP's flex to my phone yesterday. Too much water maybe, my phone started acting weird after installation, really dimmed display, touch screen not registering touch, and etc.
So I opened up the phone per ifixit's instruction, attempting to see if there's really any water in there so I can dry the components up.
At the time of opening it up, didn't notice any water at all, while the screen still remains not responding. At the end, the phone finally failed to boot (white Google screen looping). So I put everything back on, and finally leave it looping on my desk while I went out trying to have some fun in order to blow away this Saturday night sadness.
Magically, when I returned home after ~5 hrs, the phone is in the system and the touch screen works perfectly again. Also, the screen is showing images normally again. I happily went to bed with my phone.
This [sad] morning, volume button won't work. Opened it up, found that the volume switch (which was soldered onto the mobo) was ripped off (probably by careless me). Refer to this pic here. EDIT: sorry I still can't post outside link.
Here's the image: guide-images.ifixit.net/igi/2k6S4vvKPZh2IsB2.huge
Now I'm left alone: the phone is a imported GSM, seemingly not supported by anyone in the U.S. right now. Moreover, since the volume switch is soldered onto the mobo, and I am very sure I will ruin the phone if I try to re-solder the switch onto the mobo (it's some finest soldering on there), not to mention that the Cable Ribbon of the volume switch seems to be ruined as well, I think my only option is to get a totally new mobo that has volume switch soldered onto it.
To summarize:
1.Do I need a new mobo, if I find no one to help me repair the phone?
2.Where can I get a new mobo? (searched on eBay w/o results)
3.Will changing the mobo affect anything? I assume the data and system would be lost, but how about the identity of my phone?
4.If there's one agent in the U.S. that you think would take care of this uncostly (~$100?), who would you refer? Maybe Verizon, Samsung, or someone else?
5.If all of the above attempts fail at the end, I'll be considering selling it at a deep discount to someone who's got his way of restoring this phone, where would you recommend for me to go find such a talented Nexus lover? Will eBay fulfill this purpose the best?
Finally, thanks for you, the fellow members, for your help in advance. I hate myself for opening up the phone, now, thinking that the phone may have recovered for good w/o being opened up by me. Now that it has recovered with a broken volume switch in its body, making this issue much more complicated
Again, thanks...

shoulda turned off the phone right after it started acting funky and put it in a bag a rice

it sounds like you jumped the gun and opened the phone prematurely. How long did you wait to open up the phone after you installed the screen guard?
As far as your situation, I would probably cut my losses, get what I can out of it on eBay and buy another one.

Should have I also shouldve stayed with a dry apply film. Being a perfectionist, I almost knew I would ruin the phone by over spraying the application solution for a easier and better application

Actually, immediately. I didn't know the gaps around the glass screen is also the entrance for the water to get into the phone. I thought only headset speaker could let some water into it. After disassembled the phone, I realized that the water can easily get into the phone thru the gap, which leads the water right onto the mobo underneath the glass... Again, I didn't notice any water inside the phone, but i could be just moisture that's playing some nasty game here. I also did some intensive swing and tossing of the phone to get water out, until there's no water coming out.
Anyhow, I just went to Verizon store, and they said they wouldn't touch anything GSM, and said the only option for me seems to contact Samsung. Or as you said, I could sell it on eBay. Don't know how much it's worth though

I had to open up my Gnex last week because i dropped it in a puddle of water while getting out of my car...
If i remember correctly, the vol rocker is glued to the internal part that comes out with the screen and most of the electronics, so i cant imagine how you would have torn it off...
Its connectected to the main pcb via a connector though, sure you didn't just unplug the connector??
You could also try to go without the volume rocker, use some kind of widget for volume control, not ideal but cheaper than a new Gnex

Ooo, I'm sorry for both of us...
Yes, the volume switch is double-side taped, but the other end (the cable ribbon itself) is soldered onto the back of the mobo in my phone. I don't know how or what force ripped it off of the mobo. The cable ribbon is torn pretty harshly... I'll upload a pic when I make past the 10 posts and "unlock all capabilities"..

Also, did you notice any "sequela" after the incident? Does your phone function good now? There's time that on my phone the touch screen does not respond/register touch anymore suddenly. I usually just leave it standby with screen off. Usually, after 1+ hr, when I turn the screen back on, the touchscreen works fine...
Driving me crazy, this bad luck.

Guys,
Here's another issue... How do I get into fastboot mode if my volume rockers don't work..?
Tried Toolkit V4.1 and it keeps saying waiting for device..

Install the app called quickboot, it lets u go direcrly into recovery or bootloader without holding volume keys.

Thank you sir, I'll give it a try!
OOPS.. I'm not rooted...so it's a no-go

Hey cswithxda, have you found a way to fix it without replacing the mobo?
I live in Brazil, a friend of mine brought one bought at Negri electronics at US for me. It suffered an accident (part of it involves someone pushing down a window over it) and the screen cracked.
I've sent it back to Negri for RMA Repair to fix the screen and they did it, but before shipping back, found that the volume buttons weren't working. They canceled the shipment and found out that the volume cable was broken (the screen crack was near to the volume buttons, so I guess it wasn't them that broke it while fixing the screen).
Well, I've actually paid for the screen repair and ship back, but they claim that their repair facility was unable to fix the volume... any light over this?

Sorry I can't help buddy, at the time I owned the device, it was still pretty new, so I couldn't find a source that actually sells GNex motherboard. I think the only way to fix a ripped rocker button is to replace mobo if you don't find anywhere to solder it for you.
Important part is this, for whoever got the chance, buy it from Amazon! The rep was kind enough to issue me an RMA after knowing my ripped volume rocker is my own fault, and while I was actually trying to ask him about where to send it to fix. They just gave me an RMA and let me send it back and get anything else I want. Amazon customer service another miracle!

epic 4g touch Water Damaged

well guys, i kinda left my phone sitting nexto my glass of water when i was sleeping, woke up..and the phone was off, and the battery had a RED TAB on it. SO i put it in a bag of rice for 2 days, turned it on with a new battery and it worked COMPLETELY FINE, i used it all day, that night i turned it off and when i tried to turn it on the next morning something went wrong, The galaxy S2 logo shows up, closes then pops up again, then it boots up to the main screen where my lock screen is, the touch screen doesn't work at all anymore, So i boot it up into recovery mode, and i go to try a factory reset, and the power button doesn't let me select anything.but when i hit the little menu button on the bottom left, it takes the recovery to a loading screen, so the touch screen must be working right???... SOO i thought that id try a 1 click ROM, so i tried to connect it to my computer,and the computer doesn't read it AT ALL....i put it into ODIN mode, tried connecting it again, nothing, SOOO i really dont know what to do here, it was working perfectly fine... and the WERID THING is, when it turns on to the lock screen, i can receive texts,emails,phone calls, and the phone is updating games and stuf i have installed...i just cant unlock the screen, so if ANYONE could help me here it would be greatly appreciated, Thank you

Sounds like your phone had residual moisture trapped inside and that seeped into circuits or connections and caused a short that's borking your digitizer.
Whenever you have a water mishap like that you need to disassemble your phone and pack all the pieces in rice or suspend them in front of an air conditioner while letting the cold dry air blow over and around the parts overnight.
The a/c part I know first hand because my wife toilet bombed her epic last summer, and that's what I did, reassembled the next morning and its still working fine.
Of coarse when the phone hit the water it was pulled instantly and I pulled the battery and instantly disassembled the phone.
In your case I don't know if disassembling it now will help.
You may need parts to fix it.
Start Googling. There is NO software that's going to fix your phone.

From me to you on an Epic Touch running the best rom ever.

When I got my first one I went overboard off the boat I was working on. Five minutes in the water, it was toast. That was salt water though...

Liquipel, email them and ask them to officially support the Sprint GS2 as well as the AT&T & Tmobile that they already support for waterproofing, I already did and they said they'd do it, but it's not official yet cuz not enough people have been asking I think for the ET4G version.

[Q] Water damaged/Bricked??

i dropped my phone last night during heavy rain and forgot about him for about 30-45 mins when i went back out and got it the battery was out. i turned him on and he booted up to the lock screen but then i couldnt unlock it so i turned it off and put it in rice for about 12 hours and i turned it on and it got stuck at the lock screen again. Then it wouldnt boot up past the kernel splash at all nor go into recovery. i got it in download mode and odined to stock but still no go. It seems to be going very very very slow because i just randomlly found it in recovery and the volume controls were very slow and the home button wouldnt do anything. can someone help me? any advice anything to try out? its like its water damaged and bricked.
Edit: i got it to boot but it is the slowest thing ive ever seen. any suggestions?

Sounds like you have a water logged defective unit on your hands. Aside from dismantling the thing and drying out the insides, you probably have a paper weight on your hands.
Sorry man.

thanks for the reply. i guess i need to find a new phone somewhere.

So I ordered a replacment and the guy emphasized on the "as long as its not water damaged" part so does anyone know if theres like a water damage indicator inside the phone that may have changed or show that some water may have gotten in the phone?

Majority of phones have a water saturation indicator on in the inside. However, I couldn't tell you where that is located in our's. You could search a bit on the internet, I'm sure you could find a tear down video or something.

I did a little search and apparently the only indicator is on the battery so I should have no problems. The phone does turn on it just takes about an hour to get passed the Samsung screen so hopefully they wont look too deep for any water problems.

Okay, so after letting my phone sit with no battery for like 5 hours i tried to turn it on and it worked 100%. It was back on stock since i odin'd stock FC09 on it. Then I flashed cwm and restored my backup and i ended up with the same touch screen problems. So now I'm back at the point where i just odin'd stock on my phone and it still won't boot passed the samsung screen. I'm going to take out the battery and let it sit. Can anyone explain why this is happening? Could this one time working event be just a random thing or is it from leaving the phone alone for the few hours I did? Any suggestions or thoughts?

The touch screen problems sound like it's hardware related. As for it not booting passed the sammy screen idk.

water damage - black screen...

my wife dropped her z1 compact in the toilet yesterday.
she wiped it off and put it in a bag of rice, to get rid of the moist.
it was working when she put it in there, but after a few hours when we took it out to check it, the screen wouldn't light up.
it was (is) still working though, cause she got lots of messages.
i can see that there is water inside since there are tiny drops of water inside the flash and the camera looks all moist inside...
today, it's the same story, but now the problem is even bigger, since i tried all sorts of fixes i could find, which included turning the phone off/ rebooting (powerbutton+volume up).
i had hoped to hook it up to a computer and transfer all the photos, but since i can't see the screen, i can't enter the pincode and get access to her phone.
when i do connect it to a computer, it starts loading, so the connection seems fine, but since i can't "enter" the phone, the computer won't recognize it as a device.
do you know of any way to at least save the photos?
would it it be possible to use the warrany for this?

If it still connects OK, there's probably hope with adb...

I wouldn't do anything with it until all traces of water have gone. This might take a couple of days. Open all the flaps while it is drying in the rice.

Well, You could try connecting the phone via HDMI and at least get an display. And the by making assumptions of where the numbers are, You could press the passcode and connect it to pc then.

The first thing you should have done after picking it from the water was to turn off the device. Less risk of something shorting out like it probably did in your case.

Try keeping it for a week iinside rice or silicon bag.
And you can't claim warranty unless the phone is faulty!
