The power button - LG Optimus 3D

My power button broke. That little flat cable teared up a bit. Can someone please help me find one? Im from Serbia and there are no spare parts like that here. I soldered a button from an old nokia phone just so i could use my phone temporarily. If i take my phone to service they'll tell me that the motherboard needs to be replaced and they'll charge me more than the phone is worth. So i need help with this from you guys. Can someone find this for me on ebay? Please...

the small cable that connected to the copper frame under the button is cut , but i think it should work when i try to connect it manually with the copper frame
is there any suggestions plzzz
plz guyss any helppppppppppppp
You cut the cable?!
No idea. Why can't you just take it back to a repair centre so someone with more experience can fix it properly for you?

I am a samsung tech and I order the screen as a whole.
Only bits you save are the mainboard,back,battery and battery cover.
everything else is replaced.
if you find anything else on ebay its a fake part and will void your warranty if anything else goes wrong.
So if you do take it to a service centre they will charge you for a £90 part and labour
why it doesnt work when i connect the cable manually ???? hell why all of samsung galaxy parts r hard to deal with !!! , hard to replace the screen , hard to fix anything
its not my problem when i want to replace the screen and its glued to everything , its idiot
Samsungs are very easy to fix if you have official parts. Phone companies are doing this to cut down the blackmarket of phone parts.

Think if that cheap fake part drawes more power then the standard and damages the mainboard why is its samsunga job to fix it?

Lock button problem.

Hello, I'm having the famous Cappy lock button problem (the one where said button doesn't work). It's not a physical problem (unless a contact has died somewhere on my motherboard) because my button feels the same as it did the day I got this phone. I've also never had any kind of problem with my power button before. I did get my phone secondhand from a friend which voided the warranty. The only way I can turn the screen on is by plugging it in or removing and replacing the battery. The only way it turns off is by timing out.
Help guys, I need some answers!
Thanks in advance.
P.S. I already tried the camera app trick and to no avail. I also can't do anything in recovery mode because the power button is also the selection button.
My button started acting up. I used a can of compressed air to spray into the edges of the button, and it's been working great ever since.

This is All very helpful, but I don't think that it is a hardware issue. I'll try all these things that you have suggested and we'll see to certain.
When you take the battery out then put it back in does it automatically turn on? If so the power button needs to be replaced....at least that's what mine and a lot of others I've seen was doing.

It's a hardware issue. What else would it be?

just disassemble it and clean the button. I had same problem on my volumn down button.

I took it apart and the motherboard was surprisingly clean. I was expecting it to be dustier, but everything looked fine. I'm now thinking it could be a micro-fracture on a solder contact. I still haven't sprayed keyboard cleaner directly on the button, so maybe I don't have to buy a whole new motherboard.

Did you replace the button yourself? I have been without my lock button for about a year now and I have kind of gotten used to it, but if the process of replacing it is fairly simple than I may just do that myself! Also where did you purchase your new lock button?

Short fall... no boot... screen flicker

Trying to fix an ATRIX 2 for a friend... he said he dropped it from about 2 feet on the a hard wood floor and it landed on its face... I've done about a good bit of searching through this ATRIX 2 community and couldn't find issue related to what is happening... phones dead for one... when I attempt to charge with moto USB/wall/ car no response when I attempt to charge from a Samsung wall charger (5.1v700mA) screen will flicker static type image then back light will remain light 5-15 sec Max.. again flicker back light then nothing.... no led response or illumination of captivate keys.... when plugged in USB into laptop (laptop on charger doesn't do it off charge) the notification led will flash white at the start of it being plugged in or after being unplugged... their is no cracks in the screen at all...should I make a factory cable and get it to boot prior to worrying about replacement of a digitizer if one was needed I know with my RAZR and d4 it would boot I just wouldn't see anything... thank you kindly for any assistance

Any thoughts...?
Sent from my DROID4 using xda app-developers app
does the laptop detect the phone ? as in installing drivers and all ? or if motocast is installed, does motocast get activated ? cause we need to know whether atleast the phones internals are responding..
No response in the least bit from the laptop... drivers are installed... I do have motocast installed for my d4... I don't even get the da-ding noise
Sent from my DROID4 using xda app-developers app
Dunno man, i guess its a motherboard problem or maybe the phone usb port problem.. you sure the battery has any power ?
Im just assuming here.. i guess your friend needs to take it to the moto repair centre..
When i get home tonight ima go ahead and make the factory cable to see if i cant get it to boot up... moto repair is not likely there is a cell repair near me but he's on the low income side and was just hoping I can get my good deed of the day out of it by a cheep or free fix... all out of my pocket... I was thinking it was something more then a digitizer as with my RAZR and d4 it would have a response from HDMI and PC would recognize them...thank you kindly for the quick reply...
Sent from my DROID4 using xda app-developers app
Factory cable had no response... so I called moto and apparently when I told him to call he didn't... moto said it was still under warranty check my email for the prepaid postage find a box and send it in... I was even gonna pay them the extended warranty fee but I got lucky there... thanks ATRIX 2 community I will return to my d4 realm

Nexus S wont turn on

I had to restart my phone. And then my screen goes blank. There is no display since. Even charger plugged on there is no indication.
There is some heat generated when the battery is charged and even after the cable is removed indicating some functioning of the phone hardware.
Tried the long power button hold and tried the power + volume up hold troubleshooting. But nothing happens.
Please help!
Do you have another battery that you can try? I had similar problems with one battery I had. I used another one and the phone was fine. Most energy problems are faulty batteries.
I don't have a spare battery and no stock of batteries here as well.
Any other suggestions?

try holding vol up + vol down...while holding, tap power
this will load download mode. If you can get it here you can reflash with odin and reinstall everything again.
try having the back cover off... plug the phone into a known working charger / cable with the battery in. let it sit for 10 secs, then quickly pull the battery out and plug the battery in (like half a second... just enough to disconnect the battery from the contacts) this should force the phone to turn on.
Its how i turn my nexus s on without a power button.

Could be the power button. This is a known issue and something similar happened to me. Turned phone off and wouldn't turn back on. Tried everything - just had to jam the power button. Had it replaced twice for that reason. I fixed my third by disassembling and cleaning and reseating power button.

Thanks for all the suggestions. Apparently the motherboard needs a change. And since I had bought it in a different region, the motherboard available here is not suitable.

Too bad! Maybe you can get one online. I found this one on ebay:
http://item.mobileweb.ebay.com/viewitem?itemId=121053149092&index=3&nav=SEARCH&nid=59354008011
If you search a little bit more and in more places I'm sure you can find something. Or you can use this as an excuse to get a new phone!

You can't buy a motherboard none is selling them, if u want to fix ur phone u need to send it for repair to samsung or an alternative repair shop, but none of those 2 will sell u a mobo...
I was searching on ebay for some time and 2 ads i found were for dead motherboards and this in 4 months of searching. I mailed a dozen repair shops and they all decline to sell me a mobo or they didn't carry them at all
Anyway to repair ur phone by replacing the mobo will cost you 100-150$ ur better of buying a new phone for around 200$ cause the nexus s is too old and doesn't justify the repair / value / performance compare to other phones on the market right now
I have had this same problem and if my cousin finds out that this phone might be broken he will be upset. But i can change the motherboard, if i do will i lose all my data like music messages apps etc. ?

How to fix a phone when you have "deleted" its ability to charge

So I just did this.
My phone was dead. A paperweight. It in its coffin, its box.
Until I received a message from one awesome person who told me I can still save my phone.
Basically, what I did was wipe out my recovery and wipe a lot of other stuff using TWRP recovery and using format data and advanced options.
My phone wouldnt even charge so I gave up hope.
Then I received an awesome message from an awesome person who explained how I could still access my bootloader and guided me through this guide as to how I can flash in a stock OS- https://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
So I told my brother to charge his phone, and then took mine apart. and then took his apart. then used his battery to turn on my phone and flash the image. I did it.
then I turned my phone on and it got stuck at the google screen. Similar to the problem the first time around.
I turned it off and tried to charge it and thankfully I could. So it wasnt as bad.
So I flashed again and this time we got to another screen. Still google but a better animation.
It was taking too long to load so I turned it off and then on again.
And voila. One of the quickest boot ups I've had with the Nexus 5.
So that's how you do it. I'm not 100% sure if this is the right place for this and I apologise for the rantish style of this post but I am so happy about this.
There was a casualty though. My brothers phones power button was broken. Meaning I could only turn it off once and I wouldnt be able to turn it on unless I fix the power button.
I have not been able to fix the power button because the inner power button is broken. I,e I think it needs to be soldered back on. So thats one phone which died in order to save another.
I could look for help with someone in my family who knows how to solder stuff on and see what we can do.
Does anyone know any way I could get away with this without soldering?
even if it means I can only use the power button once. As in like, if there's any way I could turn on my phone, even just once, but then I dont need to solder?
I can keep my phone charged all the time after that...
The power button to turn it on is a very cheap piece... Think about a 2 USD 10 pcs.. buy it on eBay and take the mobo to any place that could do the job (take the old button apart and put the new one) it's sounds like a big deal but it's not
Good luck mate

Thanks man
I opened it up and the power button seems fine. Its just been separated from the motherboard so it needs to be soldered on so idk why I would need to buy a new power button.
I have no experience with soldering stuff so yes I am going to take it to a shop and ask the guy to repair it.
Still recommend to get a new power button, you'll have to go to a shop and ask somebody to do the job, it's better to do it with a brand new button
