i tried, they wont cover accidental damage. And my warrantys been voided since someone opened it up..

I bought a second hand phone and it did turn on however there were a numbers of problems with my phone, it had a power button that didnt work, unresponsive parts on the lcd and a quiet in call speaker.
Your best bet before trying to replace the whole pcb is opening your phone using a teardown guide

Make sure you read it a couple of times and go through the pics so you know what your dealing with, find the power button, make sure its intact and adjust the ribbon cables.
Otherwise just find a cell phone repairer on a classified ad like criagslist or kijiji.

I hate to say it, but it was second hand for a reason. Ever try switching the battery? How about changing the power supply?

Yes. Start simple. First check your electron hose to make sure you are getting power to the device. Also check the battery as well as the prongs that connect with the battery tabs. If things are good there, then think about tearing into the phone.

no no, dont say that. This phone was fine for 3 months, i dropped it at a club i went to and water got inside the phone....i took it to 3 repair people and they all said the Main PCB motherboard is damanged (water) soo does anyone have any idea where i can find a motherboard?? i have no problem with costs of replacing it. As long as its not more than the phone itself.

You didn't mention water damage in the OP. You said something was loose. Water damage is completly different.
Try ebay.

Hey i found these 3 ads on ebay...do you guys think that a swap of the motherboards would be fine? heres the ads. I contacted the seller and they said the battery was used and thats it but phone seemes operational....i know its a risk, but is it worth it guys?
..need help on this one.

why swap the motherboards if the new phone is working fine. Just transfer data and you're done surely?

Reason being the other phones have minor problems, like speaker doesnt work, or some of those phones wont pick up signals and i think thats due to a bad radio flash or if i just flash a radio everything should be working fine.

can someone please clarify this? if i buy a phone with a speaker problem and transfer the main PCB board to my old phone...will there still be a speaker problem? or is the speaker a separate unit itself and not related to the pcb board?

one of the phones i am bidding for says it might not be able to guarantee a connection to mobile network (send sms,make calls) could that be a radio flash problem? would i be able to fix that??
another is one of the phones boots on and shuts off, i take it that could be a bad flash or something? its only about $20. just trying to weigh my options cause the new phones are lkike bidding for $350 lol im not that rich yet

I found out that my MOTHERBOARD is fine. There was water damage but not enough to go inside to the main board! My dad tested the battery voltage and found i wasnt getting any voltage.
i went to future shop and found a lady to let me use her battery and sure enough the battery was working and phone powered on!!! so i guess my battery was shot from dropping and popping out of phone while recording a video.

ordered these from ebay....are they any good? they look decent

Those look like the batteries I got. They were about 1/2 of the claimed mah rating. Worst case, they wiill get you running, and that charger is pretty good.

Broke my phone! Screen won't turn on [SOLVED]

Hey guys. So I went ahead and dropped my phone in the bathroom. The battery cover popped off and the battery shot out. Anyways, after putting that back in and turning the phone on the screen won't turn on. The phone does actually start up as my boot sound plays and all the capacitive buttons light up. Also the touchscreen still works as I can "feel" my way around and still call make calls using the launcherpro swipe shortcuts I set up and can answer calls and such. So really the only thing is that the screen never displays anything.
Anyways I don't have TEP (look how smart I am!) and am going to take it into the sprint store that does repairs around here tomorrow morning to see what can be done. What I'm asking is for thoughts on what happened and advice if my device is not fixable by sprint. Do you think that the LCD is busted or did I just jiggle something loose inside? I saw a teardown video of the phone but they stopped before getting to the screen so I don't know what it is like in there. Also should I odin it back to stock before taking it in?
Lastly if all that fails does anybody have thoughts on those "mail it to us and we'll fix your phone" sites? I've seen it range from $120-$190 to fix a screen for the epic which I would be willing to pay if these places are for real.
Thanks for listening to my problems!

The only thing I can say is $190 is not worth it,you can buy one on ebay (where I bought my last 3 phones) for around $150 now I'm sure,and you can still keep yours to make phone calls,and you will have all those extras for parts,battery,what ever...

I'd try to odin first, but did you try booting into cwm? If the screen works on there, then it may just be a corruption attack of sorts.

Took it into a sprint store this morning, 1 hour and $35 later had it up and running with a new lcd. Tech said that when he tested the LCD on its own it worked fine, but not when he put it back together. He just replaced it with a different one and I was on my way, no questions asked.
I had no idea about the pricing on repairs! For not already having TEP or being eligible to put TEP on my phone anymore, $35 to fix hardware problems is a ridiculous price. That's some good service!

[Q] How to fix my screen?

My screen died last night. The phone works as I can hear all the sounds and my bottom buttons still light up, etc but I have a black screen.
I called a local repair shop and they stated it wasn’t worth repairing and that they’d be guessing what parts need replacement. Based on the symptoms above is this true? Can anyone tell me if they know what part I would need to buy to try the repair myself? Is it worth trying to fix myself?

There are two parts, the screen itself and the digitizer. The digitizer is the actual glass you touch, if that's not cracked, then you are good with that. The screen is the actual lcd under the glass.
Both can be found on ebay for 20-50 bucks, and there are tutorials here and on youtube to show you how to take it apart and fix it. FYI, there are two types of lcd's, one with a small ribbon and one with a wider one. The only way to know if to take your phone apart so you order the right one.

Seems like I can get both parts from Amazon Prime for less than $50 total which makes this worth a try. Can you suggest a good tool kit for this project?
Thanks!

Not worth repairing? I'ts cheap as hell to repair your issue.
**LINK**
You can also buy the replacement parts from that website as well. However, you might browse ebay first to see if you can get the parts for cheaper.
Edit: If the guys at the repair shop can't have any kind of educated idea as to what would be the problem with your screen going out then i would suggest not letting them anywhere near any of your computers either.
1. If screen turns on when the phone initially starts and then stops working when Android attempts to load then you've obviously got a software issue.
2. If screen doesn't work at all during the phone's initial startup process then you've obviously got a hardware problem.
3. A quick Google search shows the parts involved in replacing a screen and countless videos on how to do it. Takes only a few minutes to get a complete understanding of how it's done (It's not all that dissimilar from replacing a laptop screen). And it probably take 30-45 minutes, taking it slow since it would be a new process for the tech, to actually do the replacement.
4. Any semi-decent tech should be able to diagnose your problem within 5 minutes of looking at the phone and then have your phone back to you an hour and a half after receiving the parts.

#2 describes my phone except the screen came back on today so it is intermittent or possibly in the process of dying. The phone is rooted but running stock so I don't think software is the issue.

[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!

What do repair companies look for to see if warranty is void on phones?

I have a HTC one X, got the black screen of death. I assumed it was a loose connection as the phone is sometimes dropped. I found a forum online mentioning that its the motherboard thats faulty.
I had the phone fixed by HTC after the LED screen was shattered, this cost me around 140 quid. They sent me a refurbished phone, I noticed the screen flickered under certain colours but assumed it was a driver issue. I updated the phone and found 2 updates and seemed fine after that.
Then few days back I put my phone down for couple hrs and come back to it to find the screen is black. Apparently is the video driver shorting or something.
HTC basically gave me faulty phone, thats how i see it, just wondering if I was to send it off what do they look for to see if the case has been opened. Hopefully I can seal it back and they might not notice?
I wanted to fix it myself initially, because I have data on my phone thats not backed up.
Also is the motherboard replacement under warranty or?

Hello.
If you open the phone, i would assume they can see its been opened before. This can be done in many ways. Some screws show signs of having been removed, and scratches on the top of the screws also indicates this.. Then there are the "warrenty if void" stickers across places you need to breach.
Do you plan on opening up the phone? From what you write you have not yet opened the (faulty) phone you got from them, as a replacement? If they gave you a faulty phone, they did not fix the issue with it (you still have issues), and then i believe it should be straight forward to return it. Simply telling them what you write here (got it, noticed wierd stuff, updated it and then it seemed fine, but now its dead). The phone never REALLY worked, after you got it back (refurbished = phone returned to HTC that they send out to other customers as "NEW" while its in fact "CLEANED AND AS-GOOD-AS-NEW" - right?)
My advice would be to NOT OPEN the phone, start by having them replace it. If THAT fails, you can resort to opening it yourself.
Kind Regards
TwinAdk

The problem was I was kinda impatient, and assumed it was a loose connection. Also I have data on the phone and was convinced I could fix it myself (have done other phones). I know when you send the phone off they get wiped before any work is done on them.
I have opened it, there was one screw at the top of the phone with a void print on it. I didn't scuff the screw and was put back in the exact same place.
There was no void stickers or tags to move, the only thing was the battery was stuck down to the base of the phone. It's now loose, i was hoping if i just stick that back and send it off they won't notice anything. There's no marks inside or outside of the phone, look new still.

AW: What do repair companies look for to see if warranty is void on phones?
Well I think there is no way to get a new phone, because you bought a refurbished phone. There is a warranty on refurbished phones, but I'm pretty sure that its nearly impossible to proof that it was their fault or already damaged when you got it.

I bought the phone brand new from a phone company (in store), since then I've had the phone fixed 3 times. Twice was my fault, but the other fault was the touch screen buttons on the bottom of the phone. They were no longer responsive.
I basically shattered the LED screen, sent it off to HTC, paid 140 quid for repair and sent me this crappy refurbished phone back. This one had the flickering issues and eventually fried the motherboard. Something about shorting the video driver i read in another xda thread.
