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.

Im going to take it to another place tommorow and see if they can fix it....otherwise this is the 2nd smartphone that died on me. HTC told me to go to Bell...and i bought this phone 2nd hand. Trying to send my Galaxy S in was a Pain....anyone here know of good 3rd party repair services in Ontario?

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.

Please help.

Phone was working 100% perfect, I got home flashed FreeGS3 rom considering it looked bad ass. I flash it everything goes all well. Until I boot it up flash back into recovery using "quick boot". Never had a problem with that app.
I go into recovery and I got this pink screen that just won't go away.
http://img5.imageshack.us/img5/9660/imag0013h.jpg
I can get it to show recovery mode, and I did do a full system wipe along with wiping everything else, and I'm on stock JB right now and the screen still will not work.
I got it to show odin earlier but now it just won't show it.
I don't even think it will go into download mode.
As of right now the phone is on and is charging and I'm receiving messages as we speak, but like I said the screen is just all pink.
I've had clark44 help me with this problem and he has never seen this before, any help is appreciated.

It can get into download mode trust me. Your gonna have to time it just right if you cant see the screen tho. Do you have debugging on by chance so you could use adb? If so plug it in and run
adb reboot download. Granted this looks hardware related

I have a screen. Until I press the standby button on the side then it messes up lol. How do you reccomend I go into download mode? I don't have the option through the reboot menu.
Is there an app?

are you rooted? If so download terminal emulator from the playstore. and in it type
su
reboot download
and flash this in ODIN

Did u happen to drop it or bump it on anything fairly hard? I ask cuz I've seen this on other devices after a screen/digitizer replacement and it happened from the ribbon cable not being fully seated on the board, a small drop or a hard bump might have unseated it if the latch wasn't fully closed during assembly, just a suggestion cuz that's the only time I've seen the crazy pink lines like that other than when LCD has started to die

was thinkin that myself but figure if this doesnt fix it at least itll be on stock so you can get it fixed

I just remembered seeing it when I saw the pic. Happened to a cpl ppl on the og evo and the et4g. I've also known of a few phones to ship with the latches a bit loose from the factory, I had an intercept that came with the screen dead took it to sprint and the latch was open and the cable wasn't even connected, plugged it in and worked fine.

Phone has been dropped multiple times...but it's been in a case. It honestly probably is a hardware problem.

Might have to some how unroot and bring it to sprint. Good luck man
Just hit that THANKS button for fun!

Phone is unrooted and on stock I didn't buy this phone from sprint, will they still give me a new one?

Probably not.. but if it falls under the 1 year manufacture warrenty and it is defected I would fight it to the grave!

I got it off craigslist i traded some guy.
But if Sprint doesn't trade me for a new one I'm going to be sad

If you're comfortable opening it up, crack it open and check the ribbon cables for the screen and digitizer, the shock of dropping it may have jarred one or both loose from the board. Like I said the only time I've seen the crazy pink lines in the screen was from improperly seated cables
Edit: if u take it to a sprint repair center they will probably check the.connections for you if you explain to them that it was the only thing you could find related when you were looking for an answer. It could also be the LCD starting to die

[Q] Does this motherboard look like toast to you?

I was told that the numerous shorts on this motherboard can't be removed, but I don't know how these things are supposed to look anyway. Does it look obvious to you, one way or the other? Is that gluey-looking stuff the problem?

Is that a T989 motherboard?

that is not a sticky mess, that is fried (burned).

How did that happen?

Btw, how literally do "toast" and "fried" apply here? Does this look like a temperature-related problem—somehow it got too hot and essence de mobo started leaking all over (leaving that visible gunk)? Or is it something else entirely? Assuming there's enough information in that image.
I don't know how it happened. The phone has symptoms that led me to the following thread about issues with the power button: http://forum.xda-developers.com/showthread.php?t=1783404 (repeated vibration like at the beginning of the boot cycle, plus the camera flash going off)
When I dropped it off to have the power button replaced . . . well, before they opened it up, they said they thought it was a software corruption issue to be solved by re-flashing the ROM, and that the phone had probably gotten wet. (It's never been immersed, although maybe it doesn't take much ambient moisture for a phone to count as having gotten wet.) Then they called me later and said: whoa, the motherboard, we can't fix it. So I got it back, opened it up myself, and posted this image in the hopes of learning something, because I'm still not sure what to think. Following some of the power-button-related advice from the other thread does seem to help (e.g., the boot cycle proceeds much farther immediately after I tap the phone against a semi-hard surface in a way that would loosen up the power button), and I feel like that shouldn't be the case if the motherboard were such a piece of toast.

that is a gunk? I think I can speak for everone and say, we think it looks like burned, fried, melted electronics. The real test is the sniff check, if you know what it smells like.
Try scraping it with a sharp edge. If its fried, it will crumble. If gunk, it should stick to the edge.

[Q] Unglued cable digitizer Samsung Galaxy Note 2

Hello!
I just finish to "unglued" my digitizer cable on my note 2 ,
Please, just take a look at the picture, maybe can I do something to put it back.
Look like unglued..have you any idea if that flex cable it's glued or soldered ?
Thank you very much.

Wow.. I just did the exact same thing yesterday.. same spot on the cable and everything. I did it when I was replacing the glass.. I've tried taping it back.. and now I've tried gluing it , the touch kinda works but really inconsistent and annoying. I've spent way too much time trying to fix it and think I'm just gonna sell as parts now. What did you end up doing? Any luck getting it reattached? If you were successful please let me know what you did.

For me, was no way to put back this flex cable... and I think its close to impossible to make something good with this display.
I just stored that display ....for don't throw it.
Good luck!

this is a usual ribbon cable. i teared mine replacing the screen... will try to replace it and report back.
maybe it will require light smd oven soldering and that will suck big time. maybe i can just pressure it down somehow. your cases are much better, you still have the original cable and half of it is already soldered making it much easier to solder the rest.

thats not the same part, the part u listed on ebay is for the stylus. U can easily tell its not the same part as shown in the original post. Check out this youtube video at the 20:50 minute mark, it will show u the exact parts and u can tell. Youtube: https://www.youtube.com/watch?v=bxgZeb5QytM
Unfortunatly the part the original poster pictured is part of the digitizer and is near impossible to fix once ripped. all ive been able to find online is that ribbon cable being sold with the digitizer itself. If anyone else actually finds the part shown in the original post please do post back.

Motherboard replacement

Hi everyone,
I will explain as fast as possible : I have 2 OnePlus 3. One with a freeze problem (https://forum.xda-developers.com/oneplus-3/help/strange-issue-op3-t3699715=) and the second one with damaged screen but everthing working. So what if I put the motherboard of the broken screen one in the model with the freeze problem. Do you think it can works ?
Thx for reading ! And sorry for the english.

Watch JerryRigEverything teardown videos and try it and keep us updated I'm curious of the result. It'll probably work because basically what you're going to do is changing the broken screen with a solid one. (Changing motherboard will be about the same i think.)

Yup, this has to work.

It has to work but when I tried to separate the screen Bloc with the metal case it was very very hard, I used too much power and broken the screen... That was crazy.

I watched his video too, for me it was a LOT more resistant.
And finally I bought another phone (still OP3) and I'm still using it.
I tried to open the old phone again and I managed to do it using the jack connector, I used a screwdriver and levered in the jack connector (and the jack connector is still working).
